The vascular cylinder or stele in young stems consists of a ring of vascular bundles interspaced with medullary rays of parenchyma cells. Seasonal activity of the cambium replaces the isolated vascular bundles with well-defined annual rings of secondary phloem and xylem. Xylem is endarch with protoxylem found towards center of the stem and younger metaxylem towards the periphery of the stem. Protoxylem consists of annular and spiral tracheids with only tracheids found in metaxylem. True xylem vessels are lacking. Because of the greater production of xylem, the vascular cylinder is dominated by radially arranged rays of secondary xylem interspaced with medullary rays of parenchyma cells. Conspicuous resin ducts are present throughout the xylem.
Phloem is endarch but annual growth the of stem makes it difficult to distinguish between older protophloem to the periphery and younger metapholem towards center of the stem. Phloem lacks companion cells, consisting entirely of sieve tubes and phloem parenchyma. Medullary rays in the secondary phloem include protein rich albuminous cells.
A well-defined pith of parenchyma cells is occasionally interrupted by a few large resin ducts.

Pinus sabiniana, is one of five types of pine trees we see in the Sierra Nevada. It is also known as foothill pine, ghost pine, bull pine, and nut pine. The name Digger Pine supposedly came from the observation that the Paiute foraged for its seeds by digging around the base of the tree, although it is more likely that the term was first applied to the people; "Digger Indians" was in common use in California literature from the 1800s. The historically more common name Digger Pine is still in widespread use. The Jepson Manual advises avoiding the use of this name as the term "digger" is pejorative in origin. I personally like the name ghost pine because of the distinctive shape and color of these trees.
Pinus sabiniana grows at elevations between sea level and 4,000 feet (1,200 m), It grows in rocky soil under dry conditions. It commonly occurs in association with Quercus douglasii,] and "Oak/Foothill Pine vegetation" is used as a description of a type of habitat characteristic within the California chaparral and woodlands ecoregion in California, providing a sparse overstory above a canopy of the oak woodland. It is found throughout the: Sierra Nevada and Coast Ranges foothills that ring the Central, San Joaquin and interior valleys; the Transverse and Peninsular Ranges; and Mojave Desert sky islands.

The Cascade Ondae, viewed traditional-style in full profile, doesn’t have the smooth soft clouds of foliage that the usual subjects have. It is raucous, even rough, but at the same time shows its cork in a variety of colors that sets it apart from other bonsai cascades.

Bought many 2 ft seedings from Coldwater Farms. Have 6 or so along the driveway. White pines grow well in Michigan. The eastern white pine could be the tallest tree in eastern North America (230 ft). Mine are 20 ft. or so after 15 years. There are manys interesting white pine cultivars.

Le piante nella poesia.
Molti poeti hanno dedicato i loro poemi alle piante. Oggi propongo la poesia di Gabriele D’Annunzio “ La pioggia nel pineto” per illustrare le immagini che seguono.
La pineta a cui allude D’annunzio è quella di Pescara, oggi ne porta il nome, vicino a casa sua, dove queste piante erano comuni, Anche perché cerano la distilllleria dell' Aurum e la fabbrica del Parrozzo, dolce tipico dell'Abruzzo, i cui proprietari erano amici di famiglia; tanto che nel nel suo peregrinare in Italia e all'estero, "Lu Parrozzo" non gli mancava mai, tanto che gli dedicò una poesia: "..Cando mi scende pa lu gagarozzo sento li sisi dell'Abruzzu mi". Purtroppo, già dagli anni 50, queste essenze sono scomparse, come anche quasi tutta la pineta, per far posto a villette e palazzi,
a riccordo della pineta c'è oggi lo stadio dei Pini.
Ascolta. Piove
Dalle nuvole sparse.
Piove su le tamerici
Salmastre ed arse,
piove su i pini
scagliosi ed irti,
piove su i mirti
divini,
su le ginestre fulgenti
di fiori accolti,
su i ginepri folti
di coccole aulenti,………
The plants in the poem.
Many poets have dedicated their poems to the plants. Today I propose the poetry of Gabriele D'Annunzio "The rain in the pine" to illustrate the images that follow.
The pine alluded to is probably that of D'Annunzio Pescara, next to his house, where these plants were common, maybe there was a child, unfortunately, since the 50s, these species have disappeared, as well as almost all of the pine forest, to make way for houses and buildings.
Listen. It's raining
From the scattered clouds.
It rains on the tamarisk
Brackish and burned,
rain on the pines
scaly and spiky,
rain falls on the myrtles
divine,
on the broom shining
Flowers welcomed,
on the junipers thick
Fragrant pampering, .........
Las plantas en el poema.
Muchos poetas han dedicado sus poemas a las plantas. Hoy propongo la poesía de Gabriele D'Annunzio "La lluvia en el pino" para ilustrar las imágenes que siguen.
El pino que alude es, probablemente, la de Pescara, cerca su casa, donde estas plantas eran comunes, tal vez hba de niño, por desgracia, desde los años 50, estas especies han desaparecido, al igual que casi todo el bosque de pinos, para dar paso a las casas y edificios.
A whirlwind Sierra fall color weekend ended up with a surprise visit to the White Mountains to shoot the ancient Bristlecone Pines. I always wanted to spend some time up here, so it was an exciting and very pleasant side trip. I definitely want to come back and spend a few days up here.
If you have not been up here, you need to put it high on your short list of places to shoot ;-)
Several groups went just down the hill a ways to shoot a few iconic trees. Rob let on to this tree away from the crowds. We waited just a bit and were gifted with some pretty sweet light.
...looks great on black.
This is part of the truly awesome Methuselah Grove in California's White Mountains. The Bristlecone Pine trees of the Great Basin area are the longest continually living creature on the planet. The oldest has been approximately dated at 4900 years old! These are mostly far over the three thousand year old range. A mind blowing place to visit.
