In this setting Drosera alba is quite spectacular and easy to detect on wet margins of rock outcrops. Virtually geophytic at this location, this sundew inhabits the interface between wet marsh seepages rich with montane orchids and xeric desert. Within 10-15 meters of these plants are the succulents Crassula spp. and Conophytum minusculum at the margins of the succulent Karoo.
Plants from this site exhibit several unusually dark clones including one rhizome of the darkest pitchers I have ever observed. Very robust plants and lots of water at this location.
The Australian Pitcher Plant was first observed by European science in 1801 and to this day remains one of many enigmatic plants of Australia. Cephalotus has no direct relation to any of the other four known genera of pitcher plants of the world. Cephalotus follicularis is one of 100+ species of carnivorous or insectivorous plants which inhabit southwestern Australia - home of the greatest concentration of carnivorous plants in the world. It is likely that there are nearly as many species of Drosera (sundews) in soutwestern Australia as there are all species of carnivorous plants worldwide.
Plants in this series are from one of five sites visited for Cephalotus on a trip with Redfern Natural History Expeditions in October 2018. On the trip, we photographed nearly 100 species of carnivorous plants and many additional orchids during 2 weeks of travel in a relatively small area of southwest Australia.

Sarracenia minor is a species of carnivorous pitcher plant native to the southeast United States. It has an overhanging hood and translucent "windows" on the back that let in light and likely confuse insects that might be looking for an exit.

This butterwort, a carnivorous plant, though rare throughout its range is commonly locally abundant at sites of occurrence. The classic habitat is moderate to slow moving sandy tannic streams and associated open floodplain areas. It commonly occurs in proximity to other species of carnivorous plants.
This is the northernmost known occurrence for this species and only occurrence not in the coastal plain proper.
One of the best examples of classic habitat and growth habits I have observed for this species. Pinguicula primuliflora is a riparian species. Though it may be found growing away from streams, this is usually secondary to hydrology or habitat alteration and the remaining plants are able to briefly sustain in moist regions without moving water.
In typical habitat, as illustrated in several of these photos, plants will grow on the surface of fallen logs as long as sufficient moisture is present. At this private property site are: Pinguicula primuliflora, Drosera capillaris, Drosera intermedia, Sarracenia rubra (Ancestral/Sandhill variant), Sarracenia psittacina, Utricularia juncea, Utricularia purpurea, Utricularia gibba, and Utricularia subulata.
A legendary pitcher plant, Nepenthes northiana was discovered by the Victorian artist and naturalist Marianne North in the 1870's. North's paintings made in Borneo were the first depictions of this species to modern science.
This is one of a handful of Nepenthes species which are documented to be heavily impacted by overcollection and poaching that continues to this day. This plant is restricted to the region of the Bau limestone formation in Sarawak, Borneo.
Massive glade with thousands of pitchers of both H pulchella and H pulchella x chimantensis. Very likely a few clonal populations.

The small butterwort is a locally abundant yet uncommonly observed plant in habitats where it occurs. this species prefers very well drained moist sandy soils in the southeastern United States.
Though reported as an annual species, larger multi-crowned plants such as one in this series are indicative of multiple years of growth. This plant is somewhat sensitive to deep freezes and excessive moisture, so the appearance of an "annual" growth habit is commonly observed in the field.
Pinguicula pumila favors ground disturbance. Long periods of grass and shrub growth may reduce populations substantially over time. For this reason, roadsides and ditches with adequate hydrology are a common location to find the plants.
This spectacular pitcher plant is photographed in habitat from a location near the type locality. The moss forest in which this plant resides is truly amazing and unique among many habitats that I have observed.
Nepenthes jamban derives the species name from the Bahasa Indonesian word jamban, or toilet.

These few photos provide a rare opportunity to observe newly emerged and late summer pitchers of Sarracenia flava hybrids simultaneously. usually by late summer the mature summer pitchers have faded or dried due to dry habitat conditions. This year (2013) most southeastern bogs have experienced record rainfall (compared to last decade) allowing for a late summer flush of new pitchers.
This photograph of a magnificent stand of Sarracenia flava represents only 1/2 of the plants at this site in 2007. This heritage preserve is home to many species of rare and endangered plants and represents a far inland population of this species in the fall line sandhills. S flava is more typically a resident of the coastal plain of the south Atlantic and gulf coasts.
Unfortunately, after 2008, the pond and surrounding area was hit by a tornado or other high level winds and the majority of the Sarracenia flava seen here no longer exist. Studies to determine a potential cause for decline of the plants have produced no definitive answers, though it would appear that natural weather forces may have been to blame for blowing or washing many of the plants away.
addendum: After revisiting this site and recalling a similar situation in the Florida panhandle, it is possible that recent beaver activity in the lake is partially (or fully) responsible for the massive plant decline. In Florida I have observed semi-aquatic S leucophylla plants uprooted by beavers and integrated into the dam structure.
The bogs depicted in these photos are examples of well managed southeastern coastal plain habitats that have nearly disappeared in Georgia. This private property holds the best managed and largest bogs in the state.
Sustainability of these habitats requires 1) marked reduction of tree density; 2) Routine but not excessive application of fire, particularly non-growing season so that plants are not repeatedly weakened; and 3) eliminate alteration of hydrology by not puncturing hardpan commonly a result of deep bedding or furrowing by inappropriate forestry practices.
The three enemies of a healthy bog are excessive trees which draw out tremendous water daily; excessive shade; and diversion of water. Secondarily, increased nutrient flow into the bog from adjacent agricultural influences can increase grass growth resulting in reduction of species diversity. Excessive use of fire is also a problem for bogs in that this selects for more grass and burning recharges nutrients into the bog repeatedly. Winter burns are ecologically preferred as nutrients charged into the bog may leach out during the non-growing winter months resulting in much more nutrient depletion for the growing season. The majority of orchids, carnivorous plants, and other rare herbaceous plants are adapted to and prefer these nutrient poor conditions.
The Nepenthes gymnamphora/pectinata group is quite widespread and ambiguous and may contain multiple species or multiple similar species may fall under this nomenclature.
This large and likely ancient plant is one of many Sarracenia rubra in this bog complex that achieves tremendous size. Many of the Sarracenia in this area grow with roots directly in water 365 days/year.
Late summer pitchers (July 2013) following record setting rainfall in region. A rare sight to see persistent pitchers into late July.
The spines of several of Darwin's books: Insectivorous Plants, Climbing Plants, The Movements of Plants, Effects of Cross and Self Fertilisation, Forms of Flowers, and Vegetable Mould and Earth-Worms. I've read the last one – it has a memorable passage in which Darwin describes the experiments he performed on sensory perception of earthworms, including yelling at a pot of soil with worms in it, and playing a bassoon at the worms.
Drosera x 'California Sunset' is a carnivorous sundew that catches insects on its dewy leaves to compensate for the nutrient poor soils where it grows. It is a hybrid of Drosera filiformis and the similarly filiform Drosera tracyi made by Joseph A. Mazrimas in 1980.

One of the few documentations of this very rare variant in habitat. The result of many hours of walking through habitat and getting very lucky.
The all green variant is a result of a genetically derived absence of anthocyanin, one of the organic compounds that imparts a red or purple pigmentation to plants. The terminology of "Anthocyanin-Free" or "AF" is commonly used horticulturally to describe these variants. A very small percentage of most species of Sarracenia spp. pitcher plants have this expression. rarely are these plants observed in native habitat as they are highly valued in the horticultural trade.

The larger variant of Sarracenia psittacina is commonly observed in flodded habitats in the few areas where it occurs naturally. These primary localities are Okefenokee Swamp, west central Georgia along the fall line sandhills, and the Florida panhandle - most notably on Eglin Air Force Base.
In almost all natural occurences with habitat unaltered by man, the plants are found floating or associated with deep water in which the plants are not attached to any terra firma. It is unknown if the larger size is an adaptation to this habitat or if this large size has been selected by the habitat. Rarely is the much smaller S psittacina var. psittacina ever observed co-occurring with this larger variant in aquatic habitats.
One of the most fascinating Sarracenia sites I have ever seen: a true hybrid swarm. Virtually every manifestation of this hybrid imaginable was observed.
This rare to uncommon natural hybrid is from the region of the type locality in North Carolina. Sarracenia xswaniana has been documented historically from one additional site in Georgia but disappeared from the location within the last 20 years before a voucher specimen could be deposited.
Sarracenia minor is at the extreme northern extent of its range in this region. Because there are very few known co-occurrences of S minor and S purpurea remaining in all native populations of the southeastern US, observing this hybrid in the wild is quite rare.
Fortunately these few remaining plants are located on private well-managed land under routine surveillance and their survival is relatively assured.
These photos represent a population of yellow-flowered Sarracenia psittacina with normal ly colored pitchers. these plants are not Anthocyanin-free. This is one of several very small populations of this variant that I have observed in several states within the plant's range.
There has been much speculation about flower color variance in the Sarraceniaceae (when it occurs) as to whether this variation represents mutation or the influence of historic hybridization. I tend to believe that distant hybridization is the likely source for flower color variation in these populations.
This critically endangered pitcher plant is one of the most charismatic and intriguing species of the genus. The morphology is shared by one other species, Nepenthes klossii, from New Guinea.
Of interest in these photos is that the plants with the very bright light background were perched on the edge of a cliff with a 1km drop immediately behind the plants. Likely the most dangerous place I have ever photographed.
Even with the recent discovery of several giant Nepenthes species in recent years, seeing this plant in its native habitat will likely be the highlight of observing tropical pitcher plants in the wild.
