I have been fortunate to be able to recheck the private property location periodically over the past 12 years. These are the first photos I have published from this site, but fortunately the best I have been able to take.
This site has been repeatedly sprayed with herbicide (for a variety of industrial reasons) and approximately 7 years ago had been reduced to a single plant that did not regrow normally for 3 years. this is the second year that plants have flowered and set seed in the past 7 years.
Unfortunately two other very rare plants historically occurred and bloom at this site: Lilium pyrophilum and Asclepias rubra. Both species are now extirpated from the site.
Interestingly this population exhibits some growth habits similar to both classic Sarracenia rubra var. rubra and the 'Ancestral variant' that I have previously posted from west central Georgia.
Interesting red variants of the normally green/bronze Sarracenia minor at the southwestern edge of its range in Florida (though there is a population known one county south that is farther to the SW). Note the newly emerged leaves (green) compared to the more mature late summer growth leaves (red).
With regard to sundews in Western Australia it is redundant to call many species rare as there are so many locally endemic species. What is rare about these photos is capturing flowering plants of D monticola which are quite underrepresented in literature and on the net.
Droera monticola is restricted to several high elevation peaks in the Stirling Range north of Esperance in WA. For this hike all flowers were closed during the ascent, but a few began to open with enough sun during the descent of the mountain - allowing for these few photos.
Nepenthes truncata is a tropical pitcher plant native to the Philippines.

An unusually red form of this subspecies. Please compare to the "normal form" image later in this post.
It is difficult to say if this color variant is simply a variety or possibly the result of introgression with either S leucophylla or S psittacina and then generations of backcrosses. Nevertheless, an impressive variant.
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.
These six plants are among the most spectacular of the pitcher plants that I observed on this trip. there is tremendous variability in phenotype among the hybrids and probable backcrosses.
Each photo depicts a different plant or clone of which there were many more at this locality.
Seen in abundance along the lake shores at Avalanche, and a few at Lakkidi [Upper Bhavani backwaters]
Sarracenia 'Redbug' is a cultivar hybrid of Sarracenia rubra ssp. rubra and Sarracenia rubra ssp. wherryi. Although some consider Sarracenia rubra ssp. wherryi to be Sarracenia alabamensis ssp. wherryi.

Cowan's mantella is one of the most imperiled amphibian species in Madagascar. It is restricted to microhabitats heavily encroached by farming and other local agriculture. Protection of this species and its habitat relies on local community leaders who routinely monitor the habitats and facilitate outside research visits.
This specific microhabitat was comprised of low nutrient seepage slope which was populated by several species of carnivorous plants and orchids. Truly a very fragile habitat which likely cannot be recreated if damaged or destroyed.
One of the most fascinating Sarracenia sites I have ever seen: a true hybrid swarm. Virtually every manifestation of this hybrid imaginable was observed.
The carnivorous plant, Drosera cistiflora, is a South African sundew which captures and digests small insects on tentacled leaves covered in and enzyme-rich mucilaginous exudate. Many sundew species exhibit some slow leaf movement and will wrap around larger prey items. Drosera cistiflora is known for large showy flowers with a rainbow of different color variants. This white flower form is considered the "type-variant" which was originally described for the species in the 1800's. These plants are quite showy and for this trip many were in full bloom.
Another perplexing hybrid plant. This plant was barely noticed tucked away amongst tall grasses in an area of Sarracenia flava and Sarracenia psittacina. No Sarracenia purpurea var. burkii were observed within close distance of this location.
Superficially this plant is suggestive of Sarracenia xcatesbaei, the common hybrid between S. flava and S. purpurea. The plant is definitely a hybrid based on the unusual leaf structure and particularly the guard hairs peripheral to the opening of the mouth. It is also a very young plant which makes diagnosis even more difficult.
If it is in fact S flava x S psittacina, it will be the most rare naturally occurring Sarracenia hybrid i have ever seen; a hybrid that is almost never reported from naturally occurring populations. This hybrid has been observed from wild collected seed germinated and raised in a cultivated setting.
A truly outstanding and color-defying plant. I have never seen such intense color on a naturally growing Sarracenia.

I have a great deal of uncertainty about this plant. The photos do not capture the subtle differences between this plant and true S flava. Unfortunately the plant has experienced substantial damage and it is unknown if the true growth habit is reflected.
The third photo in this series compares the plant in question to known Sarracenia flava var maxima of similar size. In addition to subtle morphometric differences this plant was observed growing amongst Sarracenia rubra plants with no closeby S flava (S flava was in the region).
The most notable characteristic separating this plant from other S flava of similar size if the markedly narrower tube. This plant may require a re-examination next year during the growing season.
The plants depicted in these photos are from an increasingly rare southeastern US habitat in which both Sarracenia rubra and Sarracenia purpurea co-occur. At this site are hybrid plants mostly growing in moderate to heavy shade. As a result, the hybrid plants are typically poorly colored and spindly. Under bright light conditions this S xchelsonii hybrid is one of the most colorful natural hybrids.
This is a common insectivorous plant growing in fens and bogs. Its hollow pitcher-like leaves are filled with water. Any insects which enter the leaves are unable to escape because of the slippery surface and downward-pointing hairs. The plant then digests and absorbs the nutrients from the insects.
Photographed in the Oliphant Fen, in the Bruce Peninsula, Ontario, Canada.
This plant superficially resembles Sarracenia leucophylla, but is very likely S xmoorei backcrossed to S leucophylla one or more generations. Phenotypicaly this plant has no resemblance to any other of the hundreds of S leucophylla specimens at this locality.
The carnivorous plants depicted in these photos represent a newly discovered site for these species in Georgia. the Sarracenia psittacina of these bogs are among the largest I have ever seen. It is apparent that S psittacina in highly aquatice habitats allow for giant plant development as seen in Okefenokee swamp and on Eglin AFB.
