Default Nepenthes thorelii - a resolution.

Post originally posted by Dr Alastair Robinson on CPUK forum:






Dear all,

As of today, Nepenthes thorelii has officially been relocated in Vietnam, within Tay Ninh province, its type locality. François kindly invited me to help him continue his search for the elusive species in order to make an official determination in the event that he discovered plants of interest.

I am pleased to confirm, firstly, that François is not actually insane after all, and secondly, that the specimens studied in situ at the so-called Sữa Đá (Sua Da) site fall neatly into the description made by Lecomte in 1909, and match the specimens at the Paris herbarium perfectly. This is therefore the first time that the species has been formally identified and collected (with minimal impact on the population) by qualified botanists in one hundred and two years. Given the recent elimination of potential communities of this taxon by poachers, details of the site will not be made public for the foreseeable future, a decision made in concert with the Institute of Tropical Biology in Ho Chi Minh -- with whom we conducted the expedition -- in order to protect this critically endangered taxon. Aside from any additional photos that we are able to provide at a later juncture, this is all the information that we can offer at this time.

Congratulations, François. I'm sure that the forum will look forward to seeing some of your own photographs in due course. I have included some of my own in the interim. We extend our thanks to the members of the research institute and the Vietnam Army for their assistance in this endeavour.

Best wishes,

Alastair.

Additional lower traps.

Hello,

Here are a few more pictures, including a nice yellow variant of the species with yellow lower pitchers.
I will write some field reports on my blog when our travel is over (we have now 2 weeks of field work in Cambodia). This was of course a fantastic discovery and I am happy that we (The Institute of Tropical Biology of HCM, their Vietnamese colleagues, Alastair and myself) managed to rediscover this long lost species. At last. We are now working on setting proper conservation programs with the help of the Vietnamese authorities.
We will thoroughly document this species in the near future: new taxonomic and ecological informations will be provided so that everyone can now clealry understand this species.
In short: N. thorelii is a true lowland species which develops large subglobose pitchers characterized by a large bulbous peristome and a cordate (apple shape) lid. The tendrils are very long and the leaves are narrowly obovate. Upper pitchers are often pure yellow (at least as yellow as N. flava) and are narrowly infundibular and obovate at the top, a shape reminiscent of some elongated N. aristolochioides upper pitchers. A very thin indumentum covers all the plant. The species seem to occupy a very specific habitat as it grows in the drier part of swampy habitats.
I am happy to say that all surmises that I formulated in my last paper on this species (The Elusive Nepenthes thorelii) has proved to be correct, even the botanical illustration! ;-)
