Species

Nearly 100.

Tabebuia is a neotropical genus of about 100 species in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina and central Venezuela, including the Caribbean islands of Hispaniola (Dominican Republic and Haiti) and Cuba. Well-known common names include Ipê, Poui, trumpet trees and pau d'arco.

They are large shrubs and trees growing to 5 to 50 m (16 to 160 ft.) tall depending on the species; many species are dry-season deciduous but some are evergreen. The leaves are opposite pairs, complex or palmately compound with 3–7 leaflets.

Tabebuia is a notable flowering tree. The flowers are 3 to 11 cm (1 to 4 in.) wide and are produced in dense clusters. They present a cupular calyx campanulate to tubular, truncate, bilabiate or 5-lobed. Corolla colors vary between species ranging from white, light pink, yellow, lavender, magenta, or red. The outside texture of the flower tube is either glabrous or pubescentThe fruit is a dehiscent pod, 10 to 50 cm (4 to 20 in.) long, containing numerous—in some species winged—seeds. These pods often remain on the tree through dry season until the beginning of the rainy.

Species in this genus are important as timber trees. The wood is used for furniture, decking, and other outdoor uses. It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipê wood had become readily available on the market, although certificates are occasionally forged.

Tabebuia is widely used as ornamental tree in the tropics in landscaping gardens, public squares, and boulevards due to its impressive and colorful flowering. Many flowers appear on still leafless stems at the end of the dry season, making the floral display more conspicuous. They are useful as honey plants for bees, and are popular with certain hummingbirds. Naturalist Madhaviah Krishnan on the other hand once famously took offense at ipé grown in India, where it is not native.

Lapacho teaThe bark of several species has medical properties. The bark is dried, shredded, and then boiled making a bitter or sour-tasting brownish-colored tea. Tea from the inner bark of Pink Ipê (T. impetiginosa) is known as Lapacho or Taheebo. Its main active principles are lapachol, quercetin, and other flavonoids. It is also available in pill form. The herbal remedy is typically used during flu and cold season and for easing smoker's cough. It apparently works as expectorant, by promoting the lungs to cough up and free deeply embedded mucus and contaminants. However, lapachol is rather toxic and therefore a more topical use e.g. as antibiotic or pesticide may be advisable. Other species with significant folk medical use are T. alba and Yellow Lapacho (T. serratifolia)

Tabebuia heteropoda, T. incana, and other species are occasionally used as an additive to the entheogenic drink Ayahuasca.

Mycosphaerella tabebuiae, a plant pathogenic sac fungus, was first discovered on an ipê tree.

Atualizado em 10/07/2006

 

O ipê amarelo é a árvore brasileira mais conhecida, a mais cultivada e, sem dúvida nenhuma, a mais bela. É na verdade um complexo de nove ou dez espécies com características mais ou menos semelhantes, com flores brancas, amarelas ou roxas. Não há região do país onde não exista pelo menos uma espécie dele, porém a existência do ipê em habitat natural nos dias atuais é rara entre a maioria das espécies (LORENZI,2000).

A espécie Tabebuia alba, nativa do Brasil, é uma das espécies do gênero Tabebuia que possui “Ipê Amarelo” como nome popular. O nome alba provém de albus (branco em latim) e é devido ao tomento branco dos ramos e folhas novas.

As árvores desta espécie proporcionam um belo espetáculo com sua bela floração na arborização de ruas em algumas cidades brasileiras. São lindas árvores que embelezam e promovem um colorido no final do inverno. Existe uma crença popular de que quando o ipê-amarelo floresce não vão ocorrer mais geadas. Infelizmente, a espécie é considerada vulnerável quanto à ameaça de extinção.

A Tabebuia alba, natural do semi-árido alagoano está adaptada a todas as regiões fisiográficas, levando o governo, por meio do Decreto nº 6239, a transformar a espécie como a árvore símbolo do estado, estando, pois sob a sua tutela, não mais podendo ser suprimida de seus habitats naturais.

Taxonomia

Família: Bignoniaceae

Espécie: Tabebuia Alba (Chamiso) Sandwith

Sinonímia botânica: Handroanthus albus (Chamiso) Mattos; Tecoma alba Chamisso

Outros nomes vulgares: ipê-amarelo, ipê, aipê, ipê-branco, ipê-mamono, ipê-mandioca, ipê-ouro, ipê-pardo, ipê-vacariano, ipê-tabaco, ipê-do-cerrado, ipê-dourado, ipê-da-serra, ipezeiro, pau-d’arco-amarelo, taipoca.

Aspectos Ecológicos

O ipê-amarelo é uma espécie heliófita (Planta adaptada ao crescimento em ambiente aberto ou exposto à luz direta) e decídua (que perde as folhas em determinada época do ano). Pertence ao grupo das espécies secundárias iniciais (DURIGAN & NOGUEIRA, 1990).

Abrange a Floresta Pluvial da Mata Atlântica e da Floresta Latifoliada Semidecídua, ocorrendo principalmente no interior da Floresta Primária Densa. É característica de sub-bosques dos pinhais, onde há regeneração regular.

Informações Botânicas

Morfologia

As árvores de Tabebuia alba possuem cerca de 30 metros de altura. O tronco é reto ou levemente tortuoso, com fuste de 5 a 8 m de altura. A casca externa é grisáceo-grossa, possuindo fissuras longitudinais esparas e profundas. A coloração desta é cinza-rosa intenso, com camadas fibrosas, muito resistentes e finas, porém bem distintas.

Com ramos grossos, tortuosos e compridos, o ipê-amarelo possui copa alongada e alargada na base. As raízes de sustentação e absorção são vigorosas e profundas.

As folhas, deciduais, são opostas, digitadas e compostas. A face superior destas folhas é verde-escura, e, a face inferior, acinzentada, sendo ambas as faces tomentosas. Os pecíolos das folhas medem de 2,5 a 10 cm de comprimento. Os folíolos, geralmente, apresentam-se em número de 5 a 7, possuindo de 7 a 18 cm de comprimento por 2 a 6 cm de largura. Quando jovem estes folíolos são densamente pilosos em ambas as faces. O ápice destes é pontiagudo, com base arredondada e margem serreada.

As flores, grandes e lanceoladas, são de coloração amarelo-ouro. Possuem em média 8X15 cm.

Quanto aos frutos, estes possuem forma de cápsula bivalvar e são secos e deiscentes. Do tipo síliqua, lembram uma vagem. Medem de 15 a 30 cm de comprimento por 1,5 a 2,5 cm de largura. As valvas são finamente tomentosas com pêlos ramificados. Possuem grande quantidade de sementes.

As sementes são membranáceas brilhantes e esbranquiçadas, de coloração marrom. Possuem de 2 a 3 cm de comprimento por 7 a 9 mm de largura e são aladas.

Reprodução

A espécie é caducifólia e a queda das folhas coincide com o período de floração. A floração inicia-se no final de agosto, podendo ocorrer alguma variação devido a fenômenos climáticos. Como a espécie floresce no final do inverno é influenciada pela intensidade do mesmo. Quanto mais frio e seco for o inverno, maior será a intensidade da florada do ipê amarelo.

As flores por sua exuberância, atraem abelhas e pássaros, principalmente beija-flores que são importantes agentes polinizadores. Segundo CARVALHO (2003), a espécie possui como vetor de polinização a abelha mamangava (Bombus morio).

As sementes são dispersas pelo vento.

A planta é hermafrodita, e frutifica nos meses de setembro, outubro, novembro, dezembro, janeiro e fevereiro, dependendo da sua localização. Em cultivo, a espécie inicia o processo reprodutivo após o terceiro ano.

Ocorrência Natural

Ocorre naturalmente na Floresta Estaciobal Semidecicual, Floresta de Araucária e no Cerrado.

Segundo o IBGE, a Tabebuia alba (Cham.) Sandw. é uma árvore do Cerrado, Cerradão e Mata Seca. Apresentando-se nos campos secos (savana gramíneo-lenhosa), próximo às escarpas.

Clima

Segundo a classificação de Köppen, o ipê-amarelo abrange locais de clima tropical (Aw), subtropical úmido (Cfa), sutropical de altitude (Cwa e Cwb) e temperado.

A T.alba pode tolerar até 81 geadas em um ano. Ocorre em locais onde a temperatura média anual varia de 14,4ºC como mínimo e 22,4ºC como máximo.

Solo

A espécie prefere solos úmidos, com drenagem lenta e geralmente não muito ondulados (LONGHI, 1995).

Aparece em terras de boa à média fertilidade, em solos profundos ou rasos, nas matas e raramente cerradões (NOGUEIRA, 1977).

Pragas e Doenças

De acordo com CARVALHO (2003), possui como praga a espécie de coleópteros Cydianerus bohemani da família Curculionoideae e um outro coleóptero da família Chrysomellidae. Apesar da constatação de elevados índices populacionais do primeiro, os danos ocasionados até o momento são leves. Nas praças e ruas de Curitiba - PR, 31% das árvores foram atacadas pela Cochonilha Ceroplastes grandis.

ZIDKO (2002), ao estudar no município de Piracicaba a associação de coleópteros em espécies arbóreas, verificou a presença de insetos adultos da espécie Sitophilus linearis da família de coleópteros, Curculionidae, em estruturas reprodutivas. Os insetos adultos da espécie emergiram das vagens do ipê, danificando as sementes desta espécie nativa.

ANDRADE (1928) assinalou diversas espécies de Cerambycidae atacando essências florestais vivas, como ingazeiro, cinamomo, cangerana, cedro, caixeta, jacarandá, araribá, jatobá, entre outras como o ipê amarelo.

A Madeira

A Tabebuia alba produz madeira de grande durabilidade e resistência ao apodrecimento (LONGHI,1995).

MANIERI (1970) caracteriza o cerne desta espécie como de cor pardo-havana-claro, pardo-havan-escuro, ou pardo-acastanhado, com reflexos esverdeados. A superfície da madeira é irregularmente lustrosa, lisa ao tato, possuindo textura media e grã-direita.

Com densidade entre 0,90 e 1,15 grama por centímetro cúbico, a madeira é muito dura (LORENZI, 1992), apresentando grande dificuldade ao serrar.

A madeira possui cheiro e gosto distintos. Segundo LORENZI (1992), o cheiro característico é devido à presença da substância lapachol, ou ipeína.

Usos da Madeira

Sendo pesada, com cerne escuro, adquire grande valor comercial na marcenaria e carpintaria. Também é utilizada para fabricação de dormentes, moirões, pontes, postes, eixos de roda, varais de carroça, moendas de cana, etc.

Produtos Não-Madeireiros

A entrecasca do ipê-amarelo possui propriedades terapêuticas como adstringente, usada no tratamento de garganta e estomatites. É também usada como diurético.

O ipê-amarelo possui flores melíferas e que maduras podem ser utilizadas na alimentação humana.

Outros Usos

É comumente utilizada em paisagismo de parques e jardins pela beleza e porte. Além disso, é muito utilizada na arborização urbana.

Segundo MOREIRA & SOUZA (1987), o ipê-amarelo costuma povoar as beiras dos rios sendo, portanto, indicado para recomposição de matas ciliares. MARTINS (1986), também cita a espécie para recomposição de matas ciliares da Floresta Estacional Semidecidual, abrangendo alguns municípios das regiões Norte, Noroeste e parte do Oeste do Estado do Paraná.

Aspectos Silviculturais

Possui a tendência a crescer reto e sem bifurcações quando plantado em reflorestamento misto, pois é espécie monopodial. A desrrama se faz muito bem e a cicatrização é boa. Sendo assim, dificilmente encopa quando nova, a não ser que seja plantado em parques e jardins.

Ao ser utilizada em arborização urbana, o ipê amarelo requer podas de condução com freqüência mediana.

Espécie heliófila apresenta a pleno sol ramificação cimosa, registrando-se assim dicotomia para gema apical. Deve ser preconizada, para seu melhor aproveitamento madeireiro, podas de formação usuais (INQUE et al., 1983).

Produção de Mudas

A propagação deve realizada através de enxertia.

Os frutos devem ser coletados antes da dispersão, para evitar a perda de sementes. Após a coleta as sementes são postas em ambiente ventilado e a extração é feita manualmente. As sementes do ipê amarelo são ortodoxas, mantendo a viabilidade natural por até 3 meses em sala e por até 9 meses em vidro fechado, em câmara fria.

A condução das mudas deve ser feita a pleno sol. A muda atinge cerca de 30 cm em 9 meses, apresentando tolerância ao sol 3 semanas após a germinação.

Sementes

Os ipês, espécies do gênero Tabebuia, produzem uma grande quantidade de sementes leves, aladas com pequenas reservas, e que perdem a viabilidade em poucos dias após a sua coleta. A sua conservação vem sendo estudada em termos de determinação da condição ideal de armazenamento, e tem demonstrado a importância de se conhecer o comportamento da espécie quando armazenada com diferentes teores de umidade inicial, e a umidade de equilíbrio crítica para a espécie (KANO; MÁRQUEZ & KAGEYAMA, 1978).

As levíssimas sementes aladas da espécie não necessitam de quebra de dormência. Podem apenas ser expostas ao sol por cerca de 6 horas e semeadas diretamente nos saquinhos. A quebra natural leva cerca de 3 meses e a quebra na câmara leva 9 meses. A germinação ocorre após 30 dias e de 80%.

As sementes são ortodoxas e há aproximadamente 87000 sementes em cada quilo.

Preço da Madeira no Mercado

O preço médio do metro cúbico de pranchas de ipê no Estado do Pará cotado em Julho e Agosto de 2005 foi de R$1.200,00 o preço mínimo, R$ 1509,35 o médio e R$ 2.000,00 o preço máximo (CEPEA,2005).

This one was a bonus. Towards the end of our trip we had seen so many orchids we had lost track a bit of what we had seen. When we stopped for this one I first thought it was "just" another red Satyrium like we had seen before. Luckily I took some more photos because I liked the deep red colour because only afterwards I realized that what we had seen before was S. sceptrum and this one was Satyrium monadenum.

Pelargonium is a genus of flowering plants that includes about 280 species of perennials, succulents, and shrubs, commonly called geraniums, pelargoniums, or storksbills. Geranium is also the botanical name and common name of a separate genus of related plants, also known as cranesbills. Both genera belong to the family Geraniaceae. Carl Linnaeus originally included all the species in one genus, Geranium, and they were later separated into two genera by Charles Louis L'Héritier de Brutelle in 1789.

 

While Geranium species are mostly temperate herbaceous plants, dying down in winter, Pelargonium species are evergreen perennials indigenous to warm temperate and tropical regions of the world, with many species in southern Africa. They are drought and heat tolerant but can tolerate only minor frosts. Some species are extremely popular garden plants, grown as houseplants and bedding plants in temperate regions. They have a long flowering period, with flowers mostly in red, orange, or white, but intensive breeding has produced a huge array of cultivars with great variety in size, flower colour, leaf form and aromatic foliage.

 

Etymology

 

One of hundreds of garden and houseplant cultivars

The name Pelargonium is derived from the Greek πελαργός, pelargós (stork), because the seed head looks like a stork's beak. Dillenius originally suggested the name 'stork', because Geranium was named after a crane — "a πελαργός, ciconia, sicuti vocamus Gerania, γερανός, grus" (from pelargos, stork, as we call the Gerania, geranos, crane).

 

Description

Pelargonium occurs in a large number of growth forms, including herbaceous annuals, shrubs, subshrubs, stem succulents and geophytes. The erect stems bear five-petaled flowers in umbel-like clusters, which are occasionally branched. Because not all flowers appear simultaneously, but open from the centre outwards, this is a form of inflorescence is referred to as pseudoumbels.

 

The flower has a single symmetry plane (zygomorphic), which distinguishes it from the Geranium flower, which has radial symmetry (actinomorphic). Thus the lower three (anterior) petals are differentiated from the upper two (posterior) petals. The posterior sepal is fused with the pedicel to form a hypanthium (nectary tube). The nectary tube varies from only a few millimeters, up to several centimeters, and is an important floral characteristic in morphological classification. Stamens vary from 2 to 7, and their number, position relative to staminodes, and curvature are used to identify individual species. There are five stigmata in the style. For the considerable diversity in flower morphology, see figure 1 of Röschenbleck et al. (2014).

 

Leaves are usually alternate, and palmately lobed or pinnate, often on long stalks, and sometimes with light or dark patterns. The leaves of Pelargonium peltatum (Ivy-leaved Geranium), have a thick cuticle better adapting them for drought tolerance.

 

Taxonomy

 

Dillenius' introduction of the term 'Pelargonium' in Hortus Elthamensis 1732

 

Pelargonium inquinans, (Geranium Afric. arborescens), Hortus Elthamensis

Pelargonium is the second largest genus (after Geranium) within the family Geraniaceae, within which it is sister to the remaining genera of the family in its strict sense, Erodium, Geranium, and Monsonia including Sarcocaulon. The Geraniaceae have a number of genetic features unique amongst angiosperms, including highly rearranged plastid genomes differing in gene content, order and expansion of the inverted repeat.

 

Genus history

The name Pelargonium was first proposed by Dillenius in 1732, who described and illustrated seven species of geraniums from South Africa that are now classified as Pelargonium. Dillenius, who referred to these seven species with apparent unique characteristics as Geranium Africanum (African Geranium) suggested "Possent ergo ii, quibus novi generis cupido est, ea, quorum flores inaequales vel et irrregulares sunt, Pelargonia vocare" (Those who wish a new genus can therefore call those, whose flowers are unequal or irregular, ‘Pelargonia’). The name was then formally introduced by Johannes Burman in 1738. However Carl Linnaeus who first formally described these plants in 1753 did not recognise Pelargonium and grouped together in the same genus (Geranium) the three similar genera Erodium, Geranium, and Pelargonium. Linnaeus' reputation prevented further differentiation for forty years. The eventual distinction between them was made by Charles L’Héritier based on the number of stamens or anthers, seven in the case of Pelargonium. In 1774, P. cordatum, P. crispum, P. quercifolium and P. radula were introduced, followed by P. capitatum in 1790.

 

Circumscription

Pelargonium is distinguished from the other genera in the family Geraniaceae by the presence of a hypanthium, which consists of an adnate nectar spur with one nectary, as well as a generally zygomorphic floral symmetry.

 

Subdivision

De Candolle first proposed dividing the genus into 12 sections in 1824, based on the diversity of growth forms. Traditionally the large number of Pelargonium species have been treated as sixteen sections, based on the classification of Knuth (1912) who described 15 sections, as modified by van der Walt et al. (1977-1997) who added Chorisma, Reniformia and Subsucculentia.

 

These are as follows;

 

section Campylia (Lindley ex Sweet) de Candolle

section Chorisma (Lindley ex Sweet) de Candolle

section Ciconium (Sweet) Harvey

section Cortusina (DC.) Harvey

section Glaucophyllum Harvey

section Hoarea (Sweet) de Candolle

section Isopetalum (Sweet) de Candolle

section Jenkinsonia (Sweet) de Candolle

section Ligularia (Sweet) Harvey

section Myrrhidium de Candolle

section Otidia (Lindley ex Sweet) de Candolle

section Pelargonium (Sweet) Harvey

section Peristera de Candolle

section Polyactium de Candolle

section Reniformia (Knuth) Dreyer

section Subsucculentia J.J.A. van der Walt

Phylogenetic analyses

All subdivision classifications had depended primarily on morphological differences till the era of phylogenetic analyses (Price and Palmer 1993). However phylogenetic analysis shows only three distinct clades, labelled A, B and C. In this analysis not all sections were monophyletic, although some were strongly supported including Chorisma, Myrrhidium and Jenkinsonia, while other sections were more paraphyletic. This in turn has led to a proposal, informal at this stage, of a reformulation of the infrageneric subdivision of Pelargonium.

 

In the proposed scheme of Weng et al. there would be two subgenera, based on clades A+B, and C respectively and seven sections based on subclades. Subsequent analysis with an expanded taxa set confirmed this infrageneric subdivision into two groups which also correspond to chromosome length (<1.5 μ, 1.5-3.0μ), but also two subclades within each major clade, suggesting the presence of four subgenera, these correspond to clades A, B, C1 and C2 of the earlier analysis, A being by far the largest clade with 141 taxa. As before the internal structure of the clades supported monophyly of some sections (Myrrhidium, Chorisma, Reniformia, Pelargonium, Ligularia and Hoarea) but paraphyly in others (Jenkinsonia, Ciconium, Peristera). A distinct clade could be identified within the paraphyletic Polyactium, designated section Magnistipulacea. As a result, Polyactium has been split up to provide this new section, which in itself contains two subsections, Magnistipulacea and Schizopetala, following Knuth's original treatment of Polyactium as having four subsections.

 

Subgenus Pelargonium section Otidia: P. crithmifolium

Thus Röschenbleck et al. (2014) provide a complete revision of the subgeneric classification of Pelargonium based on four subgenera corresponding to their major clades (A, B, C1, C2);

 

subgenus Magnipetala Roeschenbl. & F. Albers Type: Pelargonium praemorsum (Andrews) F Dietrich

subgenus Parvulipetala Roeschenbl. & F. Albers Type: Pelargonium hypoleucum Turczaninow

subgenus Paucisignata Roeschenbl. & F. Albers Type: Pelargonium zonale (L.) L'Hér. in Aiton

subgenus Pelargonium L'Hér. Type: Pelargonium cucullatum (L.) Aiton

Sixteen sections were then assigned to the new subgenera as follows, although many species remained only assigned to subgenera at this stage

Species

Main article: List of Pelargonium species

Pelargonium has around 280 species. Röschenbleck et al lists 281 taxa. There is considerable confusion as to which Pelargonium are true species, and which are cultivars or hybrids. The nomenclature has changed considerably since the first plants were introduced to Europe in the 17th century.

 

Distribution

Pelargonium is a large genus within the family Geraniaceae, which has a worldwide distribution in temperate to subtropical zones with some 800 mostly herbaceous species. Pelargonium itself is native to southern Africa (including Namibia) and Australia. Southern Africa contains 90% of the genus, with only about 30 species found elsewhere, predominantly the East African rift valley (about 20 species) and southern Australia, including Tasmania. The remaining few species are found in southern Madagascar, Yemen, Iraq, Asia Minor, the north of New Zealand and isolated islands in the south Atlantic Ocean (Saint Helena and Tristan da Cunha) and Socotra in the Indian Ocean. The centre of diversity is in southwestern South Africa where rainfall is confined to the winter, unlike the rest of the country where rainfall is predominantly in the summer months. Most of the Pelargonium plants cultivated in Europe and North America have their origins in South Africa.

 

Ecology

Pelargonium species are eaten by the caterpillars of some Lepidoptera species, including the noctuid moth angle shades, Phlogophora meticulosa. The diurnal butterflies Cacyreus marshalli and C. tespis (Lycaenidae), native to southern Africa, also feed on Geranium and Pelargonium. C. marshallii has been introduced to Europe and can develop into a pest on cultivated Pelargoniums. It has naturalised along the Mediterranean, but does not survive the winter in Westen Europe.

 

The Japanese beetle, an important agricultural insect pest, becomes rapidly paralyzed after consuming flower petals of the garden hybrids known as "zonal geraniums" (P. × hortorum). The phenomenon was first described in 1920, and subsequently confirmed. Research conducted by Dr. Christopher Ranger with the USDA Agricultural Research Service and other collaborating scientists have demonstrated the excitatory amino acid called quisqualic acid present within the flower petals is responsible for causing paralysis of the Japanese beetle. Quisqualic acid is thought to mimic L-glutamic acid, which is a neurotransmitter in the insect neuromuscular junction and mammalian central nervous system.

 

A study by the Laboratory of Apiculture & Social Insects group at the University of Sussex on the attractiveness of common garden plants to pollinators found that a cultivar of Pelargonium × hortorum was unattractive to pollinators in comparison to other selected garden plants such as Lavandula (lavender) and Origanum.

 

Pests and diseases

Main articles: List of geranium diseases, Pelargonium flower break virus, and Pelargonium line pattern virus

The geranium bronze butterfly is a pest of Pelargonium species. The larvae of the geranium bronze bore into the stem of the host plant, causing the stem to typically turn black and die soon after. Geranium bronze are currently listed as an A2 quarantine pest by the European and Mediterranean Plant Protection Organization and can cause significant damage to Pelargonium species.

 

Cultivation

 

Pelargonium triste, the first species of its genus to be cultivated, here shown in its native habitat in Cape Town

Various types of Pelargonium are regular participants in flower shows and competitive events, with numerous societies devoted exclusively to their cultivation. They are easy to propagate vegetatively from cuttings. It is recommended that cuttings should have at least two nodes. Zonal geraniums grow in U.S. Department of Agriculture hardiness zones 9 through 12. Zonal geraniums are basically tropical perennials. Although they are often grown as annuals, they may overwinter in zones as cool as zone 7.

 

Cultivation history

The first species of Pelargonium known to be cultivated was P. triste, a native of South Africa. It was probably brought to the Botanical Garden in Leiden before 1600 on ships which had stopped at the Cape of Good Hope. In 1631, the English gardener John Tradescant the elder bought seeds from Rene Morin in Paris and introduced the plant to England. By 1724, P. inquinans, P. odoratissimum, P. peltatum, P. vitifolium, and P. zonale had been introduced to Europe.

 

Cultivars

 

Zonal pelargonium

There was little attempt at any rational grouping of Pelargonium cultivars, the growing of which was revived in the mid-twentieth century, and the origins of many if not most were lost in obscurity. In 1916 the American botanist Liberty Hyde Bailey (1858–1954) introduced two new terms for zonal and regal pelargoniums. Those pelargoniums which were largely derived from P. zonale he referred to as P. × hortorum (i.e. from the garden), while those from P. cucullatum he named P. × domesticum (i.e. from the home) In the late 1950s a list (the Spalding List) was produced in the United States, based on nursery listings and the 1897 list of Henri Dauthenay. It described seven groups, listing each cultivar with the list of its originator, and in most cases a date. These were Species, Zonals, Variegated-Leaved, Domesticum (Regals), Ivy-Leaved, Scented-Leaved and Old. In the 1970s the British Pelargonium and Geranium Society produced a checklist and the Australian Geranium Society started to produce a register but it was not completed till its author, Jean Llewellyn's death in 1999. None of these were published. The most complete list in its time was the 2001 compilation by The Geraniaceae Group, which included all cultivars up to 1959.

 

Registration of cultivars is the responsibility of the Pelargonium & Geranium Society (PAGS: formed in 2009 from the British Pelargonium and Geranium Society and the British and European Geranium Society) which administers the International Register of Pelargonium Cultivars. PAGS is the International Cultivar Registration Authority (ICRA) of the International Society for Horticultural Science for pelargoniums.

  

Contrasting leaves: Ivy-leaved Group (Left) Zonal Group (Right)

Cultivated pelargoniums are commonly divided into six groups in addition to species pelargoniums and primary hybrids. The following list is ordered by position in the PAGS classification. Abbreviations indicate Royal Horticultural Society usage.

 

A. Zonal (Z)

B. Ivy-leaved (I)

C. Regal (R)

D. Angel (A)

E. Unique (U)

F. Scented-leaved (Sc)

G. Species

H. Primary hybrids

Of these, A, U and Sc groups are sometimes lumped together as Species Derived (Sppd). This term implies that they are closely related to a species from which they were derived, and do not fit into the R, I or Z groups.

 

In addition to the primary groups, additional descriptors are used. The Royal Horticultural Society has created description codes. These include;

 

Cactus (Ca)

Coloured foliage (C)

Decorative (Dec)

Double (d)

Dwarf (Dw)

Dwarf Ivy-leaved (Dwl)

Frutetorum (Fr)

Miniature (Min)

Miniature Ivy-leaved (MinI)

Stellar (St)

Tulip (T)

Variegated (v)

These may then be combined to form the code, e.g. Pelargonium 'Chelsea Gem' (Z/d/v), indicating Zonal Double with variegated foliage. Crosses between groups are indicated with an ×, e.g. Pelargonium 'Hindoo' (R × U), indicating a Regal × Unique cross.

 

A. Zonal pelargoniums (Pelargonium × hortorum Bailey)

 

Pelargonium × hortorum (Zonal)

These are known as zonal geraniums because many have zones or patterns in the center of the leaves,[36] this is the contribution of the Pelargonium zonale parent. Common names include storksbill, fish or horseshoe geraniums.[50] They are also referred to as Pelargonium × hortorum Bailey. Zonal pelargoniums are tetraploid, mostly derived from P. inquinans and P. zonale, together with P. scandens and P. frutetorum.

 

Zonal pelargoniums are mostly bush-type plants with succulent stems grown for the beauty of their flowers, traditionally red, salmon, violet, white or pink. The scarlet colouring is attributed to the contribution of P. inquinans. Flowers may be double or single. They are the pelargoniums most often confused with genus Geranium, particularly in summer bedding arrangements. This incorrect nomenclature is widely used in horticulture, particularly in North America.

 

Zonals include a variety of plant types along with genetic hybrids such as hybrid ivy-leaved varieties that display little or no ivy leaf characteristics (the Deacons varieties), or the Stellar varieties. Hybrid zonals are crosses between zonals and either a species or species-derived pelargonium. There are hundreds of zonal cultivars available for sale, and like other cultivars are sold in series such as 'Rocky Mountain', each of which is named after its predominant colour, e.g. 'Rocky Mountain Orange', 'White', 'Dark Red', etc.

  

'Rocky Mountain Orange' (Zonal)

(i) Basic plants – Mature plants with foliage normally exceeding 180 mm (7 in) in height above the rim of the pot. For exhibition these should be grown in a pot exceeding 120 mm (4+3⁄4 in) in diameter but not normally exceeding 165 mm (6+1⁄2 in).

(ii) Dwarf plants – Smaller than basic. Mature plants with foliage more than 125 mm (5 in) above the rim of the pot, but not normally more than 180 mm (7 in). For exhibition should be grown in a pot exceeding 90 mm (3+1⁄2 in) but not exceeding 120 mm (4+3⁄4 in). They should not exceed 200 mm in height, grown in an 11 cm pot.

(iii) Miniature plants – Slowly growing pelargoniums. Mature plants with foliage normally less than 125 mm (5 in) above the rim of the pot. For exhibition should be grown in a pot not exceeding 90 mm (3+1⁄2 in). They should not exceed 125 mm in height, grown in a 9 cm pot.

(iv) Micro-miniature plants – Smaller and more slowly growing than miniature pelargoniums. Mature plants with foliage normally less than 100 mm (4 in) above the rim of the pot. They should not exceed 75 mm in height, grown in a 6 cm pot. Usually no separate classes for these in exhibition and will therefore normally be shown as Miniature Zonals.

(v) Deacon varieties –Genetic hybrid similar to a large Dwarf. For exhibition (when shown in a separate class), usually grown in a pot not exceeding 125 mm (5 in), otherwise as for Dwarf Zonals.

(vi) Stellar varieties – A relatively modern genetic hybrid originating from the work done by the Australian hybridiser Ted Both in the late 1950s and 1960s from crosses between Australian species and Zonal types. Easily identifiable by their distinctive half-star-shaped leaves and slim-petalled blooms which create an impression of being star shaped (or five fingered). Single varieties tend to have larger elongated triangular petals whereas doubles tend to have thin feathered petals that are tightly packed together. For exhibition purposes there is a separate class for 'Stellar' varieties, but being Zonals could be shown in an open class for Basic, Dwarf or Miniature Zonals (unless otherwise stated). Also known as "The Five-fingered Geraniums", "Staphysagroides", "Both’s Staphs", "Both’s Hybrid Staphs", "Fingered Flowers" and "Bodey’s Formosum Hybrids".

Fancy-leaf zonal pelargoniums – besides having green leaves with or without zoning, this group also have variable coloured foliage[50] that is sometimes used in classifying for exhibition purposes, e.g. ‘Bicolour’, ‘Tricolour’, ‘Bronze’ or ‘Gold’. Other foliage types are: ‘Black’ or ‘Butterfly’. There are an increasing number of these plants with showy blooms;

 

(a) Bicolour – includes those with white or cream veined leaves or those with two distinct colours with clearly defined edges, other than the basic zone.

(b) Tricolour – (May be Silver Tricolour (usually called a Silver Leaf) or a Gold Tricolour).

(i) Gold Tricolour – Leaves of many colours including red and gold, but usually with clearly defined edges of golden yellow and having a leaf zone, usually red or bronze, that overlays two or more of the other distinct leaf colours, so that the zone itself appears as two or more distinct colours.

(ii) Silver Tricolour or Silver Leaf – These tend to resemble a normal bi-colour leaf plant with two distinct colours usually of green and pale cream or white; the third colour is usually made up of bronze zoning. When this zoning overlays the green part of the leaf it is deemed to represent a silver colour.

(c) Bronze Leaved – Leaves of Green or Golden/Green with a heavy bronze or chestnut coloured centre zone which is known as a medallion. For exhibition purposes, when exhibited in specific ‘Bronze’ Leaf class – Must have over 50% of leaf surface bronze coloured. The dwarf plant ‘Overchurch’ which has a heavy bronze medallion.

(d) Gold Leaved – Leaves coloured golden/yellow or green/yellow but not showing a tendency to green. For exhibition purposes, when exhibited in specific ‘Gold’ Leaf class – Must have over 50% of leaf surface gold coloured.

(e) Black Leaved – Leaves coloured black, purple-black or with distinct large dark zones or centre markings on green.

(f) Butterfly Leaved – Leaves with a butterfly marking of distinct tone or hue in centre of leaf. This can be encompassed in many of the coloured leaf varieties.

Zonal pelargoniums have many flower types, as follows:

 

(a) Single flowered (S) – each flower pip normally having no more than five petals. This is the standard flower set for all Pelargoniums.

(b) Semi-double flowered (SD) – each flower pip normally having between six and nine petals.

(c) Double flowered (D)– each flower pip composed of more than nine petals (i.e. double the standard flower set) but not ‘hearted’ like the bud of a rose, e.g. the dwarf ‘Dovepoint’ which has full double blooms.

(d) Rosebud (or noisette) flowered – each bloom fully double and ‘hearted’. The middle petals are so numerous that they remain unopened like the bud of a rose.

(e) Tulip flowered – having semi-double blooms that never fully open. The large cup shaped petals open just sufficiently to resemble a miniature tulip.

(f) Bird's-egg group – having blooms with petals that have spots in a darker shade than the base colour, like many birds eggs.

(g) Speckled flowered group – having petals that are marked with splashes and flecks of another colour, e.g. ‘Vectis Embers’.

(h) Quilled (or cactus-flowered group, or poinsettia in USA) – having petals twisted and furled like a quill.

“Zonquil” pelargoniums result from a cross between Zonal pelargonium cultivars and P. quinquelobatum.

 

B. Ivy-leaved pelargoniums (derived from Pelargonium peltatum)

 

Pelargonium peltatum (Ivy-leaved)

Also known as "ivy geraniums". Usually of lax growth (trailing), mainly due to the long thin stems, with thick, waxy ivy-shaped stiff fleshy evergreen leaves developed by the species P. peltatum to retain moisture during periods of drought. Much used for hanging pots, tubs and basket cultivation. In the UK the bulbous double-headed types are preferred whilst on the European continent the balcon single types for large-scale hanging floral displays are favoured. Ivy-leaved pelargoniums embrace all such growth size types including small-leaved varieties and genetic hybrid crosses, which display little or no zonal characteristics. May have bicolour leaves and may have flowers that are single, double or rosette. Ivy pelargoniums are often sold as series such as 'Great Balls of Fire', in a variety of colours such as 'Great Balls of Fire Burgundy'.

 

Additional descriptive terms include;

 

Hybrid Ivy — the result of ivy × zonal crosses, but still more closely resemble ivy-leaved pelargoniums.

Fancy leaf — leaves with marked color variation, together with or other than green.

Miniature — miniature leaves and flowers, stems with short nodes, and compact growth. e.g. 'Sugar Baby' listed as Dwarf Ivy (DwI) by RHS.

C. Regal pelargoniums (Pelargonium × domesticum Bailey)

 

'Karl Offenstein' (Regal)

These are large bush-type floriferous evergreen pelargoniums. In addition to "Regals" they are also known as “Show Pelargoniums”. In the United States they are often known as the "Martha Washington" or ‘"Lady Washington" pelargoniums. They are grown primarily for the beauty and richness of their flower heads, which are large. Most of those cultivars grown currently are the result of hybridization over the last 50 years. They are very short-jointed and compact, which results in their requiring very little work in order to create a floriforous and well-rounded plant. Flowers are single, rarely double, in mauve, pink, purple or white. They have rounded, sometimes lobed or partially toothed (serrated) leaves, unlike the Zonal groups, without any type of zoning.

 

Additional descriptive terms include;

Decorative pelargoniums (Decoratives) – Descendants of older, less compact, smaller-flowered varieties that are more suited to outdoor conditions. These have smaller flowers than Regal, but are otherwise similar. e.g. ‘Royal Ascot’

Miniature – Flowers and leaves similar to Regal, but miniature in form, with compact growth. Other terms include “Pansy Geraniums” or “Pansy Pelargoniums”. e.g. ‘Lara Susan’

Oriental pelargoniums – The result of crosses between Regals and members of the Angel group (see below). Some have bicolour foliage.

D. Angel pelargoniums (derived from Pelargonium crispum)

 

'Angeleyes Randy' (Angel)

Angel pelargoniums are similar to Regal pelargoniums but more closely resemble P. crispum in leaf shape and growth habit. The majority of Angel cultivars originate from a cross between P. crispum and a Regal variety in the early part of the 20th century. Angels have grown in popularity in the last 30 years or so due mainly to an explosion of new varieties being released by specialist nurseries resulting from the work done by dedicated amateur hybridisers. These hybrisers have managed to obtain many new flower colour breaks and tighter growth habits resulting in plants suitable for all sorts of situations. Angels basically have the appearance of a small Regal with small serrated leaves and much smaller flowers and are more compact and bushy. The group extends to include similar small-leaved and -flowered types but usually with P. crispum in their parentage. They are mostly upright bush-type plants but there are some lax varieties that can be used for basket or hanging pot cultivation. Often called "pansy-faced" in the US. Some varieties have bicolour foliage. Other terms include ‘Langley-Smith Hybrids’.

 

E. Unique pelargoniums (derived from Pelargonium fulgidum)

 

Unique in sense of not fitting into any of the above categories. The parentage of Unique pelargoniums is confused and obscure. One theory being a derivation from P. fulgidum, but a derivation from an older cultivar 'Old Unique’, also known as or ‘Rollinson’s Crimson’, in the mid-19th century is also claimed. Unique pelargoniums resemble upright Scented Leaf pelargoniums in being shrubby and woody evergreens. They have distinctly scented leaves, and small flowers with blotched and feathered petals. They may have bicolour foliage. Some types, popularly known in the hobby as hybrid Uniques, have been crossed with Regal pelargoniums and, as a result of this cross, are much more floriferous.

 

Cultivar

Pelargonium graveolens (Scented leaf)

Shrubby evergreen perennials grown chiefly for their fragrance, may be species or cultivars but all must have a clear and distinct scented foliage. Scent is emitted when the leaves are touched or bruised with some scents aromatic, others pungent and in a few cases, quite unpleasant. Several of the scented leaved pelargoniums are grown for the oil geraniol, which is extracted from the leaves and is an essential oil much used commercially in perfumery. The scent of some species growing in their natural habitat, acts as a deterrent to grazing animals who appear to dislike the emitted scent. Conversely, it also attracts other insect life to visit the bloom and pollinate the plant. The scented leaves can be used for potpourri and they also have a use as flavourings in cooking. Occasionally scented types can be found in some of the other groups mentioned; for example, the Angels, having P. crispum in their genetic makeup, can often have a strong citrus scent. Leaves are lobed, toothed, incised or variegated. Growth habit is very variable, but the flowers are less prominent than other groups, and most closely resemble the species they originated from.

G. Species pelargoniums

The species are the forefathers of all the cultivar groups listed above. In general, the definition of a species is that it breeds true, and is to be found doing this in the "wild". Species pelargoniums have a large diversity of characteristics in habit, shape, size and colour, which probably accounts for them having retained their popularity for more than 300 years.

 

H. Primary hybrids

A primary hybrid is recognised as being the resultant plant from a first-time cross between two different known species. Examples are P. × ardens – from P. lobatum × P. fulgidum (1810). P. × glauciifolium – from P. gibbosum × P. lobatum (1822). Usually, but not always, primary hybrids are sterile.

Usage

Ornamental plants

Pelargoniums rank as one of the highest number of potted flowering plants sold and also in terms of wholesale value.

 

Scented leaf pelargoniums

Other than being grown for their beauty, species such as P. graveolens are important in the perfume industry and are cultivated and distilled for their scents. Although scented pelargoniums exist which have smells of citrus, mint, pine, spices or various fruits, the varieties with rose scents are most commercially important. Pelargonium distillates and absolutes, commonly known as "scented geranium oil" are sometimes used to supplement or adulterate expensive rose oils. The oils of the scented pelargoniums contain citronellol, geraniol, eugenol, alpha-pinene and many other compounds. The edible leaves and flowers are also used as a flavouring in desserts, cakes, jellies and teas. Scented-leafed pelargoniums can be used to flavor jellies, cakes, butters, ice cream, iced tea and other dishes, The rose-, lemon- and peppermint-scents are most commonly used. Also used are those with hints of peach, cinnamon and orange. Commonly used lemon-scented culinary species include P. crispum and P. citronellum. Rose-scenteds include P. graveolens and members of the P. graveolens cultivar group. Other species and cultivars with culinary use include the lime-scented P. ‘Lime’, the lemon balm-scented P. ‘Lemon Balm’, the strawberry-lemon-scented P. ‘Lady Scarborough’ and the peppermint-scented P. tomentosum.[81] Scented leaf pelargoniums have also been historically used as toilet paper by fishermen in remote places, such as the Minquiers.

 

Herbal medicine

In herbal medicine, Pelargonium has been used for intestinal problems, wounds and respiratory ailments, but Pelargonium species have also been used for fevers, kidney complaints and other conditions. Geranium (Pelargonium) oil is considered a relaxant in aromatherapy, and in recent years, respiratory/cold remedies made from P. sidoides and P. reniforme have been sold in Europe and the United States. P. sidoides along with Echinacea is used for bronchitis. P. odoratissimum is used for its astringent, tonic and antiseptic effects. It is used internally for debility, gastroenteritis, and hemorrhage and externally for skin complaints, injuries, and neuralgia and throat infections. The essential oil is used in aromatherapy.

 

Pets

According to the ASPCA, these plants are toxic to cats, dogs, and horses.

Pelargonin (pelargonidin 3,5-O-diglucoside) is a petal pigment of the scarlet pelargonium.

 

Culture

The chemist, John Dalton, realized that he was color blind in 1794 when he heard others describe the color of the flowers of the pink Pelargonium zonale as pink or red, when to him it looked either pink or blue, having no relationship to red at all.

Very variable species with the largest flowers in the genus ranging from 100-400 mm in diameter. Clump-forming succulent with fat, green, erect, deeply ribbed stems, up to 200 mm tall and 30 mm thick.

The flowers are large, star-shaped 5-petalled, pale yellow in color, with transverse crimson lines variable in color and covered with purplish or crimson hairs.

It is the most widely north-south distributed species and occurs in Zambia, Malawi, Mozambique, Botswana, Zimbabwe and South Africa.

From my collection

When you rely on the written literature you'd think that Disa ornithantha and D. erubescens are very similar. I had never seen either of them before so it was a bit of a surprise to see how recognizably different they looked in the field. The most prominent difference is that in size. D. ornithantha, though certainly not small, is less than half the size of D. erubescens. I also prefer the colour of D. ornithantha which is a much deeper red and probably was one of the most striking and stunning species we saw during our Nyika trip.

A number of Habenaria species were on the menu in Nyika, one quite literally as the budding inflorescences had all been eaten by bushbuck. Some were still in bud while others already had the flowers finished. Even when they are in their full glory is not always easy to identify the green chinese puzzles in this genus but one looked promisingly different. It is Habenaria xanthochlora a near-endemic, only found on the Nyika and in similar habitats accross the border in Southern Tanzania.

Gladiolus (from Latin, the diminutive of gladius, a sword[2]) is a genus of perennial cormous flowering plants in the iris family (Iridaceae).[3]

Gladiolus Italicus, Behbahan

Gladiolus italicus, Behbahan, Iran

It is sometimes called the 'sword lily', but is usually called by its generic name (plural gladioli).[4]

The genus occurs in Asia, Mediterranean Europe, South Africa, and tropical Africa. The center of diversity is in the Cape Floristic Region.[5] The genera Acidanthera, Anomalesia, Homoglossum, and Oenostachys, formerly considered distinct, are now included in Gladiolus.[6]

Description

Gladioli grow from round, symmetrical corms[7] (similar to crocuses) that are enveloped in several layers of brownish, fibrous tunics.[8]

Their stems are generally unbranched, producing 1 to 9 narrow, sword-shaped, longitudinal grooved leaves, enclosed in a sheath.[2] The lowest leaf is shortened to a cataphyll. The leaf blades can be plane or cruciform in cross section.

The flowers of unmodified wild species vary from very small to perhaps 40 mm across, and inflorescences bearing anything from one to several flowers. The spectacular giant flower spikes in commerce are the products of centuries of hybridisation and selection.

The flower spikes are large and one-sided, with secund, bisexual flowers, each subtended by 2 leathery, green bracts. The sepals and the petals are almost identical in appearance, and are termed tepals. They are united at their base into a tube-shaped structure. The dorsal tepal is the largest, arching over the three stamens. The outer three tepals are narrower. The perianth is funnel-shaped, with the stamens attached to its base. The style has three filiform, spoon-shaped branches, each expanding towards the apex.[9]

The ovary is 3-locular with oblong or globose capsules,[9] containing many, winged brown, longitudinally dehiscent seeds.

Wild Gladiolus, Behbahan, Iran

Gladiolus italicus, Behbahan, Iran

These flowers are variously coloured, ranging from pink to reddish or light purple with white, contrasting markings, or white to cream or orange to red.[10]

Ecology

The South African species were originally pollinated by long-tongued anthophorini bees,[11] but some changes in the pollination system have occurred, allowing pollination by sunbirds, noctuid and Hawk-moths, long-tongued flies and several others.[12] In the temperate zones of Europe many of the hybrid large flowering sorts of gladiolus can be pollinated by small well-known wasps. Actually, they are not very good pollinators because of the large flowers of the plants and the small size of the wasps. Another insect in this zone which can try some of the nectar of the gladioli is the best-known European Hawk-moth Macroglossum stellatarum which usually pollinates many popular garden flowers like Petunia, Zinnia, Dianthus and others.[13]

Gladioli are used as food plants by the larvae of some Lepidoptera species including the Large Yellow Underwing,[14] and gladiolus thrips.[15]

Horticulture

Gladioli have been extensively hybridized and a wide range of ornamental flower colours are available from the many varieties.[10] The main hybrid groups have been obtained by crossing between four or five species, followed by selection: 'Grandiflorus', 'Primulines' and 'Nanus'. They can make very good cut flowers for display.[10]

The majority of the species in this genus are diploid with 30 chromosomes (2n=30) but the Grandiflora hybrids are tetraploid and possess 60 chromosomes (2n=4x=60). This is because the main parental species of these hybrids is Gladiolus dalenii which is also tetraploid and includes a wide range of varieties (like the Grandiflora hybrids).[10]

Cultivation

In temperate zones, the corms of most species and hybrids should be lifted in autumn and stored over winter in a frost-free place, then replanted in spring. Some species from Europe and high altitudes in Africa, as well as the small 'Nanus' hybrids, are much hardier (to at least −26 °C or −15 °F) and can be left in the ground in regions with sufficiently dry winters. 'Nanus' is hardy to Zones 5–8. The large-flowered types require moisture during the growing season, and must be individually staked as soon as the sword-shaped flower heads appear. The leaves must be allowed to die down naturally before lifting and storing the corms. Plants are propagated either from small cormlets produced as offsets by the parent corms, or from seed. In either case, they take several years to get to flowering size. Clumps should be dug up and divided every few years to keep them vigorous.[15]

They are affected by thrips, (thrip simplex),[15][16] and wasps Dasyproctus bipunctatus, which burrow into the flowers causing them to collapse and die.[17]

Numerous garden cultivars have been developed, of which ‘Robinetta’ (a G. recurvus hybrid), with pink flowers, has gained the Royal Horticultural Society's Award of Garden Merit.[18][19]

In culture

Gladiolus is the birth flower of August.[20]

Gladioli are the flowers associated with a fortieth wedding anniversary.

American Ragtime composer Scott Joplin composed a rag called “Gladiolus Rag”[21]

"Gladiolus" was the word Frank Neuhauser correctly spelled to win the 1st National Spelling Bee in 1925.[22]

The Australian comedian and personality Dame Edna Everage's signature flowers were gladioli, which she referred to as "gladdies".[23]

The ancient Graeco-Roman god Pluto was said to wear a wreath of what is traditionally identified as a type of Gladiolus,[24] called phasganion or xiphion in Koine Greek.[25]

The Mancunian singer Morrissey is known to dance with gladioli hanging from his back pocket or in his hands, especially during the era of The Smiths.[26] This trait of his was made known in the music video for "This Charming Man", where he swung a bunch of yellow gladioli while singing.

From my garden

Oakland has lots of gems that nobody talks about, really.

 

After we moved here we just realize how underrated all these things in Oakland are compared to the world's famous San Francisco. This rose garden is located near Lake Merritt, and it's quite large. I guess one drawback is that it's not super well-taken care of. It's a very large rose garden with many roses, but just not maintained well. However it's also free. So we felt like they could charge just a tad bit of money and they can hire gardeners to take care of the plants and roses. It's just one way to think about.

fun facts:

The biological function of the tulip and other flowers is reproductive, therefore their purpose is mediating (pollinating) the male angiosperm with the female ovum (fertilization) for the formation and dispersal of seeds for the next generation of blossoms.

Hibiscus

 

Hibiscus L. é um gênero botânico, com cerca de 300 espécies, inserido na família das Malvaceae, com flores e folhas exuberantes. Devido à nova taxonomia pela filogenética (Angiosperm Phylogeny Group), muitas espécies que pertenciam a esse gênero estão migrando para outros gêneros. Por exemplo: Hibiscus esculentus L., a planta do quiabo, agora é Abelmoschus esculentus (L.) Moench. O cultivo dos exemplares do gênero, tanto ornamental como econômico, está disseminado nas regiões subtropicais e tropicais, cuidando para não sofrerem com geadas e temperaturas baixas constantes.

Hibiscus (/hɨˈbɪskəs/ or /haɪˈbɪskəs/) is a genus of flowering plants in the mallow family, Malvaceae. It is quite large, containing several hundred species that are native to warm-temperate, subtropical and tropical regions throughout the world. Member species are often noted for their showy flowers and are commonly known simply as hibiscus, or less widely known as rose mallow. The genus includes both annual and perennial herbaceous plants, as well as woody shrubs and small trees. The generic name is derived from the Greek word ἱβίσκος (hibískos), which was the name Pedanius Dioscorides (ca. 40–90) gave to Althaea officinalis.

 

Description:

The leaves are alternate, ovate to lanceolate, often with a toothed or lobed margin. The flowers are large, conspicuous, trumpet-shaped, with five or more petals, color from white to pink, red, orange, purple or yellow, and from 4–18 cm broad. Flower color in certain species, such as H. mutabilis and H. tiliaceus, changes with age.[5] The fruit is a dry five-lobed capsule, containing several seeds in each lobe, which are released when the capsule dehisces (splits open) at maturity. It is of red and white colours. It is an example of complete flowers.

 

Uses:

Symbolism and culture

Hibiscus species represent nations: Hibiscus syriacus is the national flower of South Korea, and Hibiscus rosa-sinensis is the national flower of Malaysia. The hibiscus is the national flower of Haiti. The red hibiscus is the flower of the Hindu goddess Kali, and appears frequently in depictions of her in the art of Bengal, India, often with the goddess and the flower merging in form. The hibiscus is used as an offering to goddess Kali and Lord Ganesha in Hindu worship.

 

In the Philippines, the gumamela (local name for hibiscus) is used by children as part of a bubble-making pastime. The flowers and leaves are crushed until the sticky juices come out. Hollow papaya stalks are then dipped into this and used as straws for blowing bubbles.

 

The hibiscus flower is traditionally worn by Tahitian and Hawaiian girls. If the flower is worn behind the left ear, the woman is married or in a relationship. If the flower is worn on the right, she is single or openly available for a relationship. The hibiscus is Hawaii's state flower.

 

Nigerian author Chimamanda Ngozi Adichie named her first novel Purple Hibiscus after the delicate flower.

 

The bark of the hibiscus contains strong bast fibres that can be obtained by letting the stripped bark set in the sea to let the organic material rot away.

 

Landscaping

Many species are grown for their showy flowers or used as landscape shrubs, and are used to attract butterflies, bees, and hummingbirds.

 

Paper

One species of Hibiscus, known as kenaf (Hibiscus cannabinus), is extensively used in paper-making.

 

Beverage

Main article: Hibiscus tea

 

The tea made of hibiscus flowers is known by many names in many countries around the world and is served both hot and cold. The beverage is well known for its color, tanginess and flavor.

 

It is known as bissap in West Africa, agua de jamaica in Mexico and Honduras (the flower being flor de jamaica) and gudhal (गुड़हल) in India. Some refer to it as roselle, a common name for the hibiscus flower. In Jamaica, Trinidad and many other islands in the Caribbean, the drink is known as sorrel (Hibiscus sabdariffa; not to be confused with Rumex acetosa, a species sharing the common name sorrel). In Ghana, the drink is known as soobolo in one of the local languages.

 

Roselle is typically boiled in an enamel-coated large stock pot as most West Indians believe the metal from aluminum, steel or copper pots will destroy the natural minerals and vitamins.[citation needed]

 

In Cambodia, a cold beverage can be prepared by first steeping the petals in hot water until the colors are leached from the petals, then adding lime juice (which turns the beverage from dark brown/red to a bright red), sweeteners (sugar/honey) and finally cold water/ice cubes.

 

In Egypt,[citation needed] Sudan and the Arab world, hibiscus tea is known as karkadé (كركديه), and is served as both a hot and a cold drink.

 

Food

Dried hibiscus is edible, and it is often a delicacy in Mexico. It can also be candied and used as a garnish.

 

The roselle (Hibiscus sabdariffa) is used as a vegetable. The species Hibiscus suratensis Linn synonymous to Hibiscus aculeatus G. Don is noted in Visayas Philippines being a souring ingredient for almost all local vegetables and menus. Known as Labog in the Visayan area, (or Labuag/Sapinit in Tagalog), the species is a very good ingredient in cooking native chicken soup. Certain species of hibiscus are also beginning to be used more widely as a natural source of food coloring (E163),[citation needed] and replacement of Red #3 / E127.

 

Hibiscus species are used as food plants by the larvae of some Lepidopteran species, including Chionodes hibiscella, Hypercompe hambletoni, the nutmeg moth, and the turnip moth.

 

Health benefits

The tea is popular as a natural diuretic; it contains vitamin C and minerals, and is used traditionally as a mild medicine.

 

A 2008 USDA study shows consuming hibiscus tea lowers blood pressure in a group of prehypertensive and mildly hypertensive adults. Three cups of tea daily resulted in an average drop of 8.1 mmHg in their systolic blood pressure, compared to a 1.3 mmHg drop in the volunteers who drank the placebo beverage. Study participants with higher blood pressure readings (129 or above) had a greater response to hibiscus tea: their systolic blood pressure went down by 13.2 mmHg. These data support the idea that drinking hibiscus tea in an amount readily incorporated into the diet may play a role in controlling blood pressure, although more research is required.

 

Studies have demonstrated the anti-hypertensive effects of H. sabdariffa in both humans and animals. It has been proposed that the antihypertensive effects of H. sabdariffa is due to its angiotensin-converting enzyme inhibiting activity. In a randomized, controlled clinical trial involving 39 patients with mild to moderate hypertension, Captopril was compared to an extract of H. sabdariffa for antihypertensive effects. Subjects taking an extract of H.sabdariffa, consumed daily before breakfast for four weeks, found reduction in blood pressure similar to Captopril. Another randomized, placebo clinical trial involving 54 study participants with moderate hypertension demonstrated a reduction in both systolic and diastolic blood pressure. However upon discontinuation of treatment, both systolic and diastolic blood pressures were subsequently elevated.

 

Hibiscus rosa-sinensis has a number of medical uses in Chinese herbology. Lokapure s.g.et al. their research indicates some potential in cosmetic skin care; for example, an extract from the flowers of Hibiscus rosa- sinensis has been shown to function as an anti-solar agent by absorbing ultraviolet radiation.

 

In the Indian traditional system of medicine, Ayurveda, hibiscus, especially white hibiscus and red hibiscus (Hibiscus rosa-sinensis), is considered to have medicinal properties. The roots are used to make various concoctions believed to cure ailments such as cough, hair loss or hair greying. As a hair treatment, the flowers are boiled in oil along with other spices to make a medicated hair oil. The leaves and flowers are ground into a fine paste with a little water, and the resulting lathery paste is used as a shampoo plus conditioner.

 

Hibiscus tea also contains bioflavonoids, which are believed to help prevent an increase in LDL cholesterol, which can increase the buildup of plaque in the arteries.

 

A previous animal study demonstrated the effects of H.sabdariffa extract on atherosclerosis in rabbits. Notably, a reduction in triglyceride, cholesterol, and low-density lipoprotein was observed in rabbits consuming a high cholesterol diet (HCD) in addition to H.sabdariffa extract compared to rabbits only fed HCD, suggesting a beneficial effect.[16] Furthermore, the H. sabdariffa seed is abundant in phytosterol and tocopherol, plant forms of cholesterol that have antioxidant and LDL cholesterol lowering effects.

 

Precautions and Contraindications:

 

Pregnancy and Lactation

While the mechanism is not well understood, previous animal studies have demonstrated both an inhibitory effect of H. sabdariffa on muscle tone and the anti-fertility effects of Hibiscus rosa-sinensis, respectively. The extract of H. sabdariffa has been shown to stimulate contraction of the rat bladder and uterus; the H.rosa-sinensis extract has exhibited contraceptive effects in the form of estrogen activity in rats. These findings have not been observed in humans. The Hibiscus rosa-sinensis is also thought to have emmenagogue effects which can stimulate menstruation and, in some women, cause an abortion. Due to the documented adverse effects in animal studies and the reported pharmacological properties, the H. sabdariffa and H.rosa-sinensis are not recommended for use during pregnancy. Additionally, they are not recommended while breastfeeding due to the lack of reliable information on its safety and use.

 

Contraindications

No contraindications have been identified.

 

Adverse Effects

Drug Interactions

It is postulated that H. sabdariffa interacts with diclofenac, chloroquine and acetaminophen by altering the pharmacokinetics. In healthy human volunteers, the H. sabdariffa extract was found to reduce the excretion of diclofenac upon co-administration. Additionally, co-administration of Karkade (H. sabdariffa), a common Sudanese beverage, was found to reduce chloroquine bioavailability. However, no statistically significant changes were observed in the pharmacokinetics of acetaminophen when administered with the Zobo (H.sabdariffa) drink. Further studies are needed to demonstrate clinical significance.

 

Species:

In temperate zones, probably the most commonly grown ornamental species is Hibiscus syriacus, the common garden hibiscus, also known in some areas as the "Rose of Althea" or "Rose of Sharon" (but not to be confused with the unrelated Hypericum calycinum, also called "Rose of Sharon"). In tropical and subtropical areas, the Chinese hibiscus (H. rosa-sinensis), with its many showy hybrids, is the most popular hibiscus.

Order: Lamiales

Family: Bignoniaceae

Tribe: Tecomeae

Genus: Tabebuia

Species

Nearly 100.

Tabebuia is a neotropical genus of about 100 species in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina and central Venezuela, including the Caribbean islands of Hispaniola (Dominican Republic and Haiti) and Cuba. Well-known common names include Ipê, Poui, trumpet trees and pau d'arco.

They are large shrubs and trees growing to 5 to 50 m (16 to 160 ft.) tall depending on the species; many species are dry-season deciduous but some are evergreen. The leaves are opposite pairs, complex or palmately compound with 3–7 leaflets.

Tabebuia is a notable flowering tree. The flowers are 3 to 11 cm (1 to 4 in.) wide and are produced in dense clusters. They present a cupular calyx campanulate to tubular, truncate, bilabiate or 5-lobed. Corolla colors vary between species ranging from white, light pink, yellow, lavender, magenta, or red. The outside texture of the flower tube is either glabrous or pubescentThe fruit is a dehiscent pod, 10 to 50 cm (4 to 20 in.) long, containing numerous—in some species winged—seeds. These pods often remain on the tree through dry season until the beginning of the rainy.

Species in this genus are important as timber trees. The wood is used for furniture, decking, and other outdoor uses. It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipê wood had become readily available on the market, although certificates are occasionally forged.

Tabebuia is widely used as ornamental tree in the tropics in landscaping gardens, public squares, and boulevards due to its impressive and colorful flowering. Many flowers appear on still leafless stems at the end of the dry season, making the floral display more conspicuous. They are useful as honey plants for bees, and are popular with certain hummingbirds. Naturalist Madhaviah Krishnan on the other hand once famously took offense at ipé grown in India, where it is not native.

Lapacho teaThe bark of several species has medical properties. The bark is dried, shredded, and then boiled making a bitter or sour-tasting brownish-colored tea. Tea from the inner bark of Pink Ipê (T. impetiginosa) is known as Lapacho or Taheebo. Its main active principles are lapachol, quercetin, and other flavonoids. It is also available in pill form. The herbal remedy is typically used during flu and cold season and for easing smoker's cough. It apparently works as expectorant, by promoting the lungs to cough up and free deeply embedded mucus and contaminants. However, lapachol is rather toxic and therefore a more topical use e.g. as antibiotic or pesticide may be advisable. Other species with significant folk medical use are T. alba and Yellow Lapacho (T. serratifolia)

Tabebuia heteropoda, T. incana, and other species are occasionally used as an additive to the entheogenic drink Ayahuasca.

Mycosphaerella tabebuiae, a plant pathogenic sac fungus, was first discovered on an ipê tree.

Tabebuia alba (Ipê-Amarelo)

Texto, em português, produzido pela Acadêmica Giovana Beatriz Theodoro Marto

Supervisão e orientação do Prof. Luiz Ernesto George Barrichelo e do Eng. Paulo Henrique Müller

Atualizado em 10/07/2006

 

O ipê amarelo é a árvore brasileira mais conhecida, a mais cultivada e, sem dúvida nenhuma, a mais bela. É na verdade um complexo de nove ou dez espécies com características mais ou menos semelhantes, com flores brancas, amarelas ou roxas. Não há região do país onde não exista pelo menos uma espécie dele, porém a existência do ipê em habitat natural nos dias atuais é rara entre a maioria das espécies (LORENZI,2000).

A espécie Tabebuia alba, nativa do Brasil, é uma das espécies do gênero Tabebuia que possui “Ipê Amarelo” como nome popular. O nome alba provém de albus (branco em latim) e é devido ao tomento branco dos ramos e folhas novas.

As árvores desta espécie proporcionam um belo espetáculo com sua bela floração na arborização de ruas em algumas cidades brasileiras. São lindas árvores que embelezam e promovem um colorido no final do inverno. Existe uma crença popular de que quando o ipê-amarelo floresce não vão ocorrer mais geadas. Infelizmente, a espécie é considerada vulnerável quanto à ameaça de extinção.

A Tabebuia alba, natural do semi-árido alagoano está adaptada a todas as regiões fisiográficas, levando o governo, por meio do Decreto nº 6239, a transformar a espécie como a árvore símbolo do estado, estando, pois sob a sua tutela, não mais podendo ser suprimida de seus habitats naturais.

Taxonomia

Família: Bignoniaceae

Espécie: Tabebuia Alba (Chamiso) Sandwith

Sinonímia botânica: Handroanthus albus (Chamiso) Mattos; Tecoma alba Chamisso

Outros nomes vulgares: ipê-amarelo, ipê, aipê, ipê-branco, ipê-mamono, ipê-mandioca, ipê-ouro, ipê-pardo, ipê-vacariano, ipê-tabaco, ipê-do-cerrado, ipê-dourado, ipê-da-serra, ipezeiro, pau-d’arco-amarelo, taipoca.

Aspectos Ecológicos

O ipê-amarelo é uma espécie heliófita (Planta adaptada ao crescimento em ambiente aberto ou exposto à luz direta) e decídua (que perde as folhas em determinada época do ano). Pertence ao grupo das espécies secundárias iniciais (DURIGAN & NOGUEIRA, 1990).

Abrange a Floresta Pluvial da Mata Atlântica e da Floresta Latifoliada Semidecídua, ocorrendo principalmente no interior da Floresta Primária Densa. É característica de sub-bosques dos pinhais, onde há regeneração regular.

Informações Botânicas

Morfologia

As árvores de Tabebuia alba possuem cerca de 30 metros de altura. O tronco é reto ou levemente tortuoso, com fuste de 5 a 8 m de altura. A casca externa é grisáceo-grossa, possuindo fissuras longitudinais esparas e profundas. A coloração desta é cinza-rosa intenso, com camadas fibrosas, muito resistentes e finas, porém bem distintas.

Com ramos grossos, tortuosos e compridos, o ipê-amarelo possui copa alongada e alargada na base. As raízes de sustentação e absorção são vigorosas e profundas.

As folhas, deciduais, são opostas, digitadas e compostas. A face superior destas folhas é verde-escura, e, a face inferior, acinzentada, sendo ambas as faces tomentosas. Os pecíolos das folhas medem de 2,5 a 10 cm de comprimento. Os folíolos, geralmente, apresentam-se em número de 5 a 7, possuindo de 7 a 18 cm de comprimento por 2 a 6 cm de largura. Quando jovem estes folíolos são densamente pilosos em ambas as faces. O ápice destes é pontiagudo, com base arredondada e margem serreada.

As flores, grandes e lanceoladas, são de coloração amarelo-ouro. Possuem em média 8X15 cm.

Quanto aos frutos, estes possuem forma de cápsula bivalvar e são secos e deiscentes. Do tipo síliqua, lembram uma vagem. Medem de 15 a 30 cm de comprimento por 1,5 a 2,5 cm de largura. As valvas são finamente tomentosas com pêlos ramificados. Possuem grande quantidade de sementes.

As sementes são membranáceas brilhantes e esbranquiçadas, de coloração marrom. Possuem de 2 a 3 cm de comprimento por 7 a 9 mm de largura e são aladas.

Reprodução

A espécie é caducifólia e a queda das folhas coincide com o período de floração. A floração inicia-se no final de agosto, podendo ocorrer alguma variação devido a fenômenos climáticos. Como a espécie floresce no final do inverno é influenciada pela intensidade do mesmo. Quanto mais frio e seco for o inverno, maior será a intensidade da florada do ipê amarelo.

As flores por sua exuberância, atraem abelhas e pássaros, principalmente beija-flores que são importantes agentes polinizadores. Segundo CARVALHO (2003), a espécie possui como vetor de polinização a abelha mamangava (Bombus morio).

As sementes são dispersas pelo vento.

A planta é hermafrodita, e frutifica nos meses de setembro, outubro, novembro, dezembro, janeiro e fevereiro, dependendo da sua localização. Em cultivo, a espécie inicia o processo reprodutivo após o terceiro ano.

Ocorrência Natural

Ocorre naturalmente na Floresta Estaciobal Semidecicual, Floresta de Araucária e no Cerrado.

Segundo o IBGE, a Tabebuia alba (Cham.) Sandw. é uma árvore do Cerrado, Cerradão e Mata Seca. Apresentando-se nos campos secos (savana gramíneo-lenhosa), próximo às escarpas.

Clima

Segundo a classificação de Köppen, o ipê-amarelo abrange locais de clima tropical (Aw), subtropical úmido (Cfa), sutropical de altitude (Cwa e Cwb) e temperado.

A T.alba pode tolerar até 81 geadas em um ano. Ocorre em locais onde a temperatura média anual varia de 14,4ºC como mínimo e 22,4ºC como máximo.

Solo

A espécie prefere solos úmidos, com drenagem lenta e geralmente não muito ondulados (LONGHI, 1995).

Aparece em terras de boa à média fertilidade, em solos profundos ou rasos, nas matas e raramente cerradões (NOGUEIRA, 1977).

Pragas e Doenças

De acordo com CARVALHO (2003), possui como praga a espécie de coleópteros Cydianerus bohemani da família Curculionoideae e um outro coleóptero da família Chrysomellidae. Apesar da constatação de elevados índices populacionais do primeiro, os danos ocasionados até o momento são leves. Nas praças e ruas de Curitiba - PR, 31% das árvores foram atacadas pela Cochonilha Ceroplastes grandis.

ZIDKO (2002), ao estudar no município de Piracicaba a associação de coleópteros em espécies arbóreas, verificou a presença de insetos adultos da espécie Sitophilus linearis da família de coleópteros, Curculionidae, em estruturas reprodutivas. Os insetos adultos da espécie emergiram das vagens do ipê, danificando as sementes desta espécie nativa.

ANDRADE (1928) assinalou diversas espécies de Cerambycidae atacando essências florestais vivas, como ingazeiro, cinamomo, cangerana, cedro, caixeta, jacarandá, araribá, jatobá, entre outras como o ipê amarelo.

A Madeira

A Tabebuia alba produz madeira de grande durabilidade e resistência ao apodrecimento (LONGHI,1995).

MANIERI (1970) caracteriza o cerne desta espécie como de cor pardo-havana-claro, pardo-havan-escuro, ou pardo-acastanhado, com reflexos esverdeados. A superfície da madeira é irregularmente lustrosa, lisa ao tato, possuindo textura media e grã-direita.

Com densidade entre 0,90 e 1,15 grama por centímetro cúbico, a madeira é muito dura (LORENZI, 1992), apresentando grande dificuldade ao serrar.

A madeira possui cheiro e gosto distintos. Segundo LORENZI (1992), o cheiro característico é devido à presença da substância lapachol, ou ipeína.

Usos da Madeira

Sendo pesada, com cerne escuro, adquire grande valor comercial na marcenaria e carpintaria. Também é utilizada para fabricação de dormentes, moirões, pontes, postes, eixos de roda, varais de carroça, moendas de cana, etc.

Produtos Não-Madeireiros

A entrecasca do ipê-amarelo possui propriedades terapêuticas como adstringente, usada no tratamento de garganta e estomatites. É também usada como diurético.

O ipê-amarelo possui flores melíferas e que maduras podem ser utilizadas na alimentação humana.

Outros Usos

É comumente utilizada em paisagismo de parques e jardins pela beleza e porte. Além disso, é muito utilizada na arborização urbana.

Segundo MOREIRA & SOUZA (1987), o ipê-amarelo costuma povoar as beiras dos rios sendo, portanto, indicado para recomposição de matas ciliares. MARTINS (1986), também cita a espécie para recomposição de matas ciliares da Floresta Estacional Semidecidual, abrangendo alguns municípios das regiões Norte, Noroeste e parte do Oeste do Estado do Paraná.

Aspectos Silviculturais

Possui a tendência a crescer reto e sem bifurcações quando plantado em reflorestamento misto, pois é espécie monopodial. A desrrama se faz muito bem e a cicatrização é boa. Sendo assim, dificilmente encopa quando nova, a não ser que seja plantado em parques e jardins.

Ao ser utilizada em arborização urbana, o ipê amarelo requer podas de condução com freqüência mediana.

Espécie heliófila apresenta a pleno sol ramificação cimosa, registrando-se assim dicotomia para gema apical. Deve ser preconizada, para seu melhor aproveitamento madeireiro, podas de formação usuais (INQUE et al., 1983).

Produção de Mudas

A propagação deve realizada através de enxertia.

Os frutos devem ser coletados antes da dispersão, para evitar a perda de sementes. Após a coleta as sementes são postas em ambiente ventilado e a extração é feita manualmente. As sementes do ipê amarelo são ortodoxas, mantendo a viabilidade natural por até 3 meses em sala e por até 9 meses em vidro fechado, em câmara fria.

A condução das mudas deve ser feita a pleno sol. A muda atinge cerca de 30 cm em 9 meses, apresentando tolerância ao sol 3 semanas após a germinação.

Sementes

Os ipês, espécies do gênero Tabebuia, produzem uma grande quantidade de sementes leves, aladas com pequenas reservas, e que perdem a viabilidade em poucos dias após a sua coleta. A sua conservação vem sendo estudada em termos de determinação da condição ideal de armazenamento, e tem demonstrado a importância de se conhecer o comportamento da espécie quando armazenada com diferentes teores de umidade inicial, e a umidade de equilíbrio crítica para a espécie (KANO; MÁRQUEZ & KAGEYAMA, 1978).

As levíssimas sementes aladas da espécie não necessitam de quebra de dormência. Podem apenas ser expostas ao sol por cerca de 6 horas e semeadas diretamente nos saquinhos. A quebra natural leva cerca de 3 meses e a quebra na câmara leva 9 meses. A germinação ocorre após 30 dias e de 80%.

As sementes são ortodoxas e há aproximadamente 87000 sementes em cada quilo.

Preço da Madeira no Mercado

O preço médio do metro cúbico de pranchas de ipê no Estado do Pará cotado em Julho e Agosto de 2005 foi de R$1.200,00 o preço mínimo, R$ 1509,35 o médio e R$ 2.000,00 o preço máximo (CEPEA,2005).

Species

Nearly 100.

Tabebuia is a neotropical genus of about 100 species in the tribe Tecomeae of the family Bignoniaceae. The species range from northern Mexico and the Antilles south to northern Argentina and central Venezuela, including the Caribbean islands of Hispaniola (Dominican Republic and Haiti) and Cuba. Well-known common names include Ipê, Poui, trumpet trees and pau d'arco.

They are large shrubs and trees growing to 5 to 50 m (16 to 160 ft.) tall depending on the species; many species are dry-season deciduous but some are evergreen. The leaves are opposite pairs, complex or palmately compound with 3–7 leaflets.

Tabebuia is a notable flowering tree. The flowers are 3 to 11 cm (1 to 4 in.) wide and are produced in dense clusters. They present a cupular calyx campanulate to tubular, truncate, bilabiate or 5-lobed. Corolla colors vary between species ranging from white, light pink, yellow, lavender, magenta, or red. The outside texture of the flower tube is either glabrous or pubescentThe fruit is a dehiscent pod, 10 to 50 cm (4 to 20 in.) long, containing numerous—in some species winged—seeds. These pods often remain on the tree through dry season until the beginning of the rainy.

Species in this genus are important as timber trees. The wood is used for furniture, decking, and other outdoor uses. It is increasingly popular as a decking material due to its insect resistance and durability. By 2007, FSC-certified ipê wood had become readily available on the market, although certificates are occasionally forged.

Tabebuia is widely used as ornamental tree in the tropics in landscaping gardens, public squares, and boulevards due to its impressive and colorful flowering. Many flowers appear on still leafless stems at the end of the dry season, making the floral display more conspicuous. They are useful as honey plants for bees, and are popular with certain hummingbirds. Naturalist Madhaviah Krishnan on the other hand once famously took offense at ipé grown in India, where it is not native.

Lapacho teaThe bark of several species has medical properties. The bark is dried, shredded, and then boiled making a bitter or sour-tasting brownish-colored tea. Tea from the inner bark of Pink Ipê (T. impetiginosa) is known as Lapacho or Taheebo. Its main active principles are lapachol, quercetin, and other flavonoids. It is also available in pill form. The herbal remedy is typically used during flu and cold season and for easing smoker's cough. It apparently works as expectorant, by promoting the lungs to cough up and free deeply embedded mucus and contaminants. However, lapachol is rather toxic and therefore a more topical use e.g. as antibiotic or pesticide may be advisable. Other species with significant folk medical use are T. alba and Yellow Lapacho (T. serratifolia)

Tabebuia heteropoda, T. incana, and other species are occasionally used as an additive to the entheogenic drink Ayahuasca.

Mycosphaerella tabebuiae, a plant pathogenic sac fungus, was first discovered on an ipê tree.

O ipê amarelo é a árvore brasileira mais conhecida, a mais cultivada e, sem dúvida nenhuma, a mais bela. É na verdade um complexo de nove ou dez espécies com características mais ou menos semelhantes, com flores brancas, amarelas ou roxas. Não há região do país onde não exista pelo menos uma espécie dele, porém a existência do ipê em habitat natural nos dias atuais é rara entre a maioria das espécies (LORENZI,2000).

A espécie Tabebuia alba, nativa do Brasil, é uma das espécies do gênero Tabebuia que possui “Ipê Amarelo” como nome popular. O nome alba provém de albus (branco em latim) e é devido ao tomento branco dos ramos e folhas novas.

As árvores desta espécie proporcionam um belo espetáculo com sua bela floração na arborização de ruas em algumas cidades brasileiras. São lindas árvores que embelezam e promovem um colorido no final do inverno. Existe uma crença popular de que quando o ipê-amarelo floresce não vão ocorrer mais geadas. Infelizmente, a espécie é considerada vulnerável quanto à ameaça de extinção.

A Tabebuia alba, natural do semi-árido alagoano está adaptada a todas as regiões fisiográficas, levando o governo, por meio do Decreto nº 6239, a transformar a espécie como a árvore símbolo do estado, estando, pois sob a sua tutela, não mais podendo ser suprimida de seus habitats naturais.

Taxonomia

Família: Bignoniaceae

Espécie: Tabebuia Alba (Chamiso) Sandwith

Sinonímia botânica: Handroanthus albus (Chamiso) Mattos; Tecoma alba Chamisso

Outros nomes vulgares: ipê-amarelo, ipê, aipê, ipê-branco, ipê-mamono, ipê-mandioca, ipê-ouro, ipê-pardo, ipê-vacariano, ipê-tabaco, ipê-do-cerrado, ipê-dourado, ipê-da-serra, ipezeiro, pau-d’arco-amarelo, taipoca.

Aspectos Ecológicos

O ipê-amarelo é uma espécie heliófita (Planta adaptada ao crescimento em ambiente aberto ou exposto à luz direta) e decídua (que perde as folhas em determinada época do ano). Pertence ao grupo das espécies secundárias iniciais (DURIGAN & NOGUEIRA, 1990).

Abrange a Floresta Pluvial da Mata Atlântica e da Floresta Latifoliada Semidecídua, ocorrendo principalmente no interior da Floresta Primária Densa. É característica de sub-bosques dos pinhais, onde há regeneração regular.

Informações Botânicas

Morfologia

As árvores de Tabebuia alba possuem cerca de 30 metros de altura. O tronco é reto ou levemente tortuoso, com fuste de 5 a 8 m de altura. A casca externa é grisáceo-grossa, possuindo fissuras longitudinais esparas e profundas. A coloração desta é cinza-rosa intenso, com camadas fibrosas, muito resistentes e finas, porém bem distintas.

Com ramos grossos, tortuosos e compridos, o ipê-amarelo possui copa alongada e alargada na base. As raízes de sustentação e absorção são vigorosas e profundas.

As folhas, deciduais, são opostas, digitadas e compostas. A face superior destas folhas é verde-escura, e, a face inferior, acinzentada, sendo ambas as faces tomentosas. Os pecíolos das folhas medem de 2,5 a 10 cm de comprimento. Os folíolos, geralmente, apresentam-se em número de 5 a 7, possuindo de 7 a 18 cm de comprimento por 2 a 6 cm de largura. Quando jovem estes folíolos são densamente pilosos em ambas as faces. O ápice destes é pontiagudo, com base arredondada e margem serreada.

As flores, grandes e lanceoladas, são de coloração amarelo-ouro. Possuem em média 8X15 cm.

Quanto aos frutos, estes possuem forma de cápsula bivalvar e são secos e deiscentes. Do tipo síliqua, lembram uma vagem. Medem de 15 a 30 cm de comprimento por 1,5 a 2,5 cm de largura. As valvas são finamente tomentosas com pêlos ramificados. Possuem grande quantidade de sementes.

As sementes são membranáceas brilhantes e esbranquiçadas, de coloração marrom. Possuem de 2 a 3 cm de comprimento por 7 a 9 mm de largura e são aladas.

Reprodução

A espécie é caducifólia e a queda das folhas coincide com o período de floração. A floração inicia-se no final de agosto, podendo ocorrer alguma variação devido a fenômenos climáticos. Como a espécie floresce no final do inverno é influenciada pela intensidade do mesmo. Quanto mais frio e seco for o inverno, maior será a intensidade da florada do ipê amarelo.

As flores por sua exuberância, atraem abelhas e pássaros, principalmente beija-flores que são importantes agentes polinizadores. Segundo CARVALHO (2003), a espécie possui como vetor de polinização a abelha mamangava (Bombus morio).

As sementes são dispersas pelo vento.

A planta é hermafrodita, e frutifica nos meses de setembro, outubro, novembro, dezembro, janeiro e fevereiro, dependendo da sua localização. Em cultivo, a espécie inicia o processo reprodutivo após o terceiro ano.

Ocorrência Natural

Ocorre naturalmente na Floresta Estaciobal Semidecicual, Floresta de Araucária e no Cerrado.

Segundo o IBGE, a Tabebuia alba (Cham.) Sandw. é uma árvore do Cerrado, Cerradão e Mata Seca. Apresentando-se nos campos secos (savana gramíneo-lenhosa), próximo às escarpas.

Clima

Segundo a classificação de Köppen, o ipê-amarelo abrange locais de clima tropical (Aw), subtropical úmido (Cfa), sutropical de altitude (Cwa e Cwb) e temperado.

A T.alba pode tolerar até 81 geadas em um ano. Ocorre em locais onde a temperatura média anual varia de 14,4ºC como mínimo e 22,4ºC como máximo.

Solo

A espécie prefere solos úmidos, com drenagem lenta e geralmente não muito ondulados (LONGHI, 1995).

Aparece em terras de boa à média fertilidade, em solos profundos ou rasos, nas matas e raramente cerradões (NOGUEIRA, 1977).

Pragas e Doenças

De acordo com CARVALHO (2003), possui como praga a espécie de coleópteros Cydianerus bohemani da família Curculionoideae e um outro coleóptero da família Chrysomellidae. Apesar da constatação de elevados índices populacionais do primeiro, os danos ocasionados até o momento são leves. Nas praças e ruas de Curitiba - PR, 31% das árvores foram atacadas pela Cochonilha Ceroplastes grandis.

ZIDKO (2002), ao estudar no município de Piracicaba a associação de coleópteros em espécies arbóreas, verificou a presença de insetos adultos da espécie Sitophilus linearis da família de coleópteros, Curculionidae, em estruturas reprodutivas. Os insetos adultos da espécie emergiram das vagens do ipê, danificando as sementes desta espécie nativa.

ANDRADE (1928) assinalou diversas espécies de Cerambycidae atacando essências florestais vivas, como ingazeiro, cinamomo, cangerana, cedro, caixeta, jacarandá, araribá, jatobá, entre outras como o ipê amarelo.

A Madeira

A Tabebuia alba produz madeira de grande durabilidade e resistência ao apodrecimento (LONGHI,1995).

MANIERI (1970) caracteriza o cerne desta espécie como de cor pardo-havana-claro, pardo-havan-escuro, ou pardo-acastanhado, com reflexos esverdeados. A superfície da madeira é irregularmente lustrosa, lisa ao tato, possuindo textura media e grã-direita.

Com densidade entre 0,90 e 1,15 grama por centímetro cúbico, a madeira é muito dura (LORENZI, 1992), apresentando grande dificuldade ao serrar.

A madeira possui cheiro e gosto distintos. Segundo LORENZI (1992), o cheiro característico é devido à presença da substância lapachol, ou ipeína.

Usos da Madeira

Sendo pesada, com cerne escuro, adquire grande valor comercial na marcenaria e carpintaria. Também é utilizada para fabricação de dormentes, moirões, pontes, postes, eixos de roda, varais de carroça, moendas de cana, etc.

Produtos Não-Madeireiros

A entrecasca do ipê-amarelo possui propriedades terapêuticas como adstringente, usada no tratamento de garganta e estomatites. É também usada como diurético.

O ipê-amarelo possui flores melíferas e que maduras podem ser utilizadas na alimentação humana.

Outros Usos

É comumente utilizada em paisagismo de parques e jardins pela beleza e porte. Além disso, é muito utilizada na arborização urbana.

Segundo MOREIRA & SOUZA (1987), o ipê-amarelo costuma povoar as beiras dos rios sendo, portanto, indicado para recomposição de matas ciliares. MARTINS (1986), também cita a espécie para recomposição de matas ciliares da Floresta Estacional Semidecidual, abrangendo alguns municípios das regiões Norte, Noroeste e parte do Oeste do Estado do Paraná.

Aspectos Silviculturais

Possui a tendência a crescer reto e sem bifurcações quando plantado em reflorestamento misto, pois é espécie monopodial. A desrrama se faz muito bem e a cicatrização é boa. Sendo assim, dificilmente encopa quando nova, a não ser que seja plantado em parques e jardins.

Ao ser utilizada em arborização urbana, o ipê amarelo requer podas de condução com freqüência mediana.

Espécie heliófila apresenta a pleno sol ramificação cimosa, registrando-se assim dicotomia para gema apical. Deve ser preconizada, para seu melhor aproveitamento madeireiro, podas de formação usuais (INQUE et al., 1983).

Produção de Mudas

A propagação deve realizada através de enxertia.

Os frutos devem ser coletados antes da dispersão, para evitar a perda de sementes. Após a coleta as sementes são postas em ambiente ventilado e a extração é feita manualmente. As sementes do ipê amarelo são ortodoxas, mantendo a viabilidade natural por até 3 meses em sala e por até 9 meses em vidro fechado, em câmara fria.

A condução das mudas deve ser feita a pleno sol. A muda atinge cerca de 30 cm em 9 meses, apresentando tolerância ao sol 3 semanas após a germinação.

Sementes

Os ipês, espécies do gênero Tabebuia, produzem uma grande quantidade de sementes leves, aladas com pequenas reservas, e que perdem a viabilidade em poucos dias após a sua coleta. A sua conservação vem sendo estudada em termos de determinação da condição ideal de armazenamento, e tem demonstrado a importância de se conhecer o comportamento da espécie quando armazenada com diferentes teores de umidade inicial, e a umidade de equilíbrio crítica para a espécie (KANO; MÁRQUEZ & KAGEYAMA, 1978).

As levíssimas sementes aladas da espécie não necessitam de quebra de dormência. Podem apenas ser expostas ao sol por cerca de 6 horas e semeadas diretamente nos saquinhos. A quebra natural leva cerca de 3 meses e a quebra na câmara leva 9 meses. A germinação ocorre após 30 dias e de 80%.

As sementes são ortodoxas e há aproximadamente 87000 sementes em cada quilo.

Preço da Madeira no Mercado

O preço médio do metro cúbico de pranchas de ipê no Estado do Pará cotado em Julho e Agosto de 2005 foi de R$1.200,00 o preço mínimo, R$ 1509,35 o médio e R$ 2.000,00 o preço máximo (CEPEA,2005).
