Dear Forum, I have been studying the type specimen of N. thorelii and I realized that the type with the lower pitchers appear to be nearly identical to those of Marcello's species 4A here: www.nepenthesofthailand.com/xplants.htmI do not think species 4 and 4A are the same thing, but it is rather difficult to make a final say so based on one photo... I think we need to look at this species 4A some more. In the type, the pitchers appear rather bulbous, but the uppers look more funnel-shaped--is that accurate François? I think species 4 looks more like this plant: www.rci.rutgers.edu/~dpevans/Nepenthes/N_sp_Thailand_A.htm

Hi Dave, Based on what we know at the moment - and François will give his opinion too, I hope - I really think that sp. 4 and 4A are N. kampotiana (my favourite within the group, and I've seen many in the wild), while sp. A is N. bokor...

Well my species flowered and it was not bi-flowered like Nepenthes from Bokor Hill.

Hi Dave and Marcello,
Actually, according to my study of the various N. thorelii material from Paris (including the lectotype): - N. thorelii pitchers are clearly ovate and sometimes globose; - The upper pitchers are indeed roughly infundibular; - In both cases, the peristome is bulbous and cylindrical, the lid is orbicular to elliptic with a cordate base. - The leaf attachememt is almost completely amplexicaul. The leaf clasps the stem at the 4/5.
I do not like to draw any conclusion based on a few pictures only, especially when it comes to the Indochinese species. But I feel, like Marcello, that the plants shown in Nong's website are N. kampotiana but is is just a surmise.
About the striped plant... I think it is very close to N. bokor or it is a hybrid involving N. bokor. The foliage is very similar. However, I am reluctant to identify it as N. bokor because, if my memory serves me right, the lid shape is rougly elliptic to triangular whereas all the N. bokor plants I checked (more than 200 plants) had orbicular or slightly elliptic lid shape with a cordate base. As far as I am concerned, the lid shape is diagnostic for N. bokor. N. bokor also develops regularly partial peduncles ("double pedicels") on both male and female inflorescences but it is not always the case.
What would be very interesting is new pictures of that (highland ?) plant. Could you provide them, Dave?
Francois.
Edit: Been looking at your plant's pitcher lid again, Dave. I am not sure about the lid shape. The picture perspective and the fact that the lid is folded prevent me from clearly identify the shape. The leaf structure is VERY similar to N. bokor. If the lid shape fits too, then it's N. bokor.

I think the leaf structure of my "unknown species A" is a perfect match for N. bokor. Also, the lowers on the plant are very similar to a few depicted several of the photographs you took at Bokor Hill.
Also, the leaf attachment is a very good match.
I think it would be pretty funny if I had this species already and did not know it!
I do believe Noa's plant (sp 4) is the same clone as mine (it is a female plant) and probably came from the same source, "an long time grower with clones collected in the sixties and seventies." "The true N. thorelii"--Not. It has also been called "N. thorelii with striped peristome" or "expanded peristome".
After reveiwing the type for N. thorelii, this plant has some features in common with N. thorelii, but the pitchers are too divergent. I don't think we seen have actually seen a living example of N. thorelii yet...
