Hello ! This is Marcello and François! This thread will serve to host the discussion on the Indochinese species as a "group".You will regularly need, in order to have a better understanding, to check Marcello Catalano's site (yeah, the "funny punk" italian guy ;D ): "Nepenthes of Thaïland": www.nepenthesofthailand.com/Marcello's site is the best source to get informations on the species of Thaïland, Cambodia, Vietnam and Lao, what we call the "Indochinese species". Below you will find an index of the various threads we made on the Indochinese species. Recognized species:By "recognized species", I'm referring to the species which are being accepted by the whole community of Nepenthes taxonomists until further official researches are made. - N. bokorensis : www.lhnn.proboards107.com/index.cgi?board=ht&action=display&thread=1750Herbarium:www.lhnn.proboards107.com/index.cgi?board=herbarium&action=display&thread=1897Field report by François Mey (Bokor Hill, Cambodia):www.lhnn.proboards107.com/index.cgi?board=show&action=display&thread=1775- N. kampotiana (firstly considered synonym of N. anamensis, it now has been reinstated): www.lhnn.proboards107.com/index.cgi?board=ht&action=display&thread=2526Herbarium:www.lhnn.proboards107.com/index.cgi?board=herbarium&action=display&thread=1728Description:www.lhnn.proboards107.com/index.cgi?board=descriptions&action=display&thread=1835- N. smilesii: Previously considered and published as “dubious”, according to Martin Cheek this taxon is conspecific with N. anamensis but it was published first.

MARKAwrote:
"Is there a key anywhere that can distinguish between the different Neps from that region? i've accumulated several plants from there over the years and there's a couple i'm not sure about. Two in particular, one was simply named 'tiger' and another has no name but looks like a thorelii / tiger. I'm not so much interested in having them identified as in learning about how to do it myself. My wife is thai so I go there quite often. I'm aware of Marcellos website but was hoping I could find something more taxonomically based."

At the moment I would say that N. thorelii is not in cultivation. If you know the location or at least the province your plants come from I can tell you what species they are, new or old. Otherwise we can just guess. For a true key we'll have to wait, I think, a couple more years at most. Marcello

Hi Marcello,
No disrespect to your website intended, I have read (at least in part) a number of times and its very useful and interesting. I have hard time looking at photos though and comparing with my plants hence I was hoping some taxonomic descriptions were available somewhere, anyway I can wait a while.
I'm wary of basing an ID purely on location. Most of the unnamed thai plants I have seem to have quite similar growth patterns e.g. cool tolerant/wet soil/rhizomes and i could imagine they could be quite widespread, would prefer to understand the actual taxonomic differences.
Regards,
Mark
Edit: Just found the thorelli description on your site ;D

MARCELLO CATALANO wrote: Hi Mark, your words were not considered by me offensive not even for a second It's just that my "easy going" (italian) nature brings me to express myself like a funny punk more than like a serious scientist (which I'm not!); when it comes to writing in a forum, the way of talking is not always well reflected by the written words (and so often I/we write so fast!): the risk I run is to seem offended or to be offensive...but I'm just here to have fun! Coming to us: The indochinese problem is a mountain. I can't explain the whole mountain - which also seems not very comprehensible by most people - every time that a plant needs to be identified, so usually I report the latest findings and perspectives that can give an idea of the situation. So, again: these plants are more or less all identical. But each species occupies a specific area, province or territory. You will never find two of these twin species growing in the same area or province (when that RARELY happens, one species grows on the mountain, the other in the lowlands, so that in fact it can't be called "the same area"). That's why having the location means having the identity. Then we have the second problem: this identity belongs to a species that already has a name or to a new species? Nowadays I can tell you that (if I have the location), but still I can't give the name of the new species and ALL their characteristics. If we don't have a location, we just have a plant that could be any of the 6-7 twin ones. We can exclude one species or two (thanks to the indumentum, leaf shape ...and to my good eye, ah ah!!), but then we are left with another 2-3. Until we don't have these new species properly described we can just guess. And I'm quite sure that half the plants going around as "tiger" are these 1-2 new species (from Phanga and Surat), the other half is probably kampotiana (Trat). But some of these "tiger" for sale could be any of the 6-7 of this messy group. That's because Thai growers just call all their local species "tiger" or "thorelii" or various mixes with these names. You see, the location (that, I know, 98 percent of times the Thai seller won't give you, because he doesn't know or because he doesn't want) is everything! About N. thorelii: forget about the description on my website, that's food for crazy people like me and François, who spend the night reading those useless words !!! Reading that, you'll just realize that it describes another plant from the twin group. N. thorelii might be a synonym of smilesii or kampotiana (as Cheek thinks) or a plant that has been forgotten, maybe extinct, that is not in cultivation and that is quite different (as I think and as François is going to prove during his next trip, hopefully!). Of course when I say "different", that's always relative! Mark, it's the end of the year, make us happy, post some photos of pitchers and leaves of your thai plants, and describe their indumentum and possibly their location. I think we can do a lot with that. Waiting for a more serious key Marcello

Are the stem/leaf attachments hyper-foliate (I think that is the word) like what is always seen in N. adnata and sometimes in N. hirsuta? The photos I have seen of the types appear to show this feature, but I cannot tell for sure one way or the other. Thanks, Crazy Dave

Dave, there's no way I can find on the web a clear idea of what hyper-foliate means, not even looking at the leaves of N. adnata, which are described as "adnate", while to me they appear just leaves! (funny thing: the definition of adnate in the dictionary is "attached to another organ, like the petal is attached to the flower or the leaf is attached to the stem", so basically "adnate" means that this particular kind of leaf is not floating in the air by itself). François, great job as always! But I think the list of recognized, pubblished, accepted and synonyms might be confusing. I would say that if we ONLY want to rely on the latest pubblications (from 10 years ago!) then we just have N. thorelii and anamensis (as you said: for anybody who knows the matter, this classification today is meaningless). All the other names are synonyms or they need to be reinstated or they still have to be described. The mess and the truth are in this second group of names (by the way, IF geoffrayi is a synonym, I think it's a synonym of kampotiana...). Marcello

Hi Marcello, Jebb and Cheek (1997) N. smilesii did not synonymise N. smilesii with any other indochinese Nepenthes. They put it in a "little known taxa" section. That's why I decided to put it in my "recognised" section. I can see your point and I even agree with you. Still, I've been asked by some growers what's official in our conclusions. I do know you might be upset by this questioning but I think it's important to know the "official work" (even if it's obsolete) and the "work in progress". Would you have a couple of moments to write a sum up of our current knowledge on these species (just copy my first message and modify it)? Speak soon mate, François.

Hi man! I sent you the document. Of course I know that people should know what is official and what is not, I agree with that and I'm not upset; on the contrary, I wanted to make more clear what is official right now, even if it's not much and it's clearly wrong...people could get confused with the terms recognized, synonym, accepted, pubblished etc, so I was just thinking about making a list of "recognized" and a list of "all the others", specifing under each taxon its status... I'm not even sure about the terms recognized, pubblished and accepted, as they all mean different things and they could include one or more of the above listed species! Maybe instead of "recognized" we should refer to the "official pubblished situation (10 years old)" and to the "unofficial unpubblished situation (present time)" !!! Marcello

Many thanks man ! I have just edited my first message. Please have a look . I think this sum up will be useful for growers who have an interest in IC species. If they want to know much further, they will have to dive in your site ;D! François.

Ah, but unlike other Nepenthes leaves in one special way... The part of the leaf which attaches to the stem goes full way around the stem, so it looks like the stem is growing through the leaf.

I see. Well, that would be huge difference, I guess taxonomists would have pointed that out, as that would make N. thorelii completely different from all its sisters! All the other narrow leaved species seem to share identical leaf attachment. Sometimes that isn't obvious because the wings at the base of the leaf change in shape during the rosette, lower and climbing stage, changing from round and short to acute and long. I gave a look at the specimens from Paris posted by François, but I think what you see is the basal wings that, being dry, curl one on the other, giving the impression that they are just one that goes all around the stem. Maybe

Yeah, I brought [Stewart] to see kampotiana, kongkandana and then another three probably new species, then he went to Phu Kradung for N. smilesii by himself He was frequently saying "what's the point in creating 10 new species when we have just two people on the planet who can see the difference!"... it might be good sense, but unfortunately taxonomy doesn't work that way Hi Cello , I bet he asked you something like: "why not merging all those plants into one variable species" such as N. mirabilis? If we were to do so, then we would have merge many other taxa as well. I'm thinking of, just among others: hispida / hirsuta of course but also boschiana / faizaliana, angasanensis / mikei, eymae / maxima... rowanae / mirabilis and many others ;D! We should rethink the whole Nepenthes taxonomy. François.

We should rethink the whole Nepenthes taxonomy. François. I don't have any trouble putting N. eymae in under the species N. maxima. I'm not familiar enough with the other species pairs to come to very solid conclusions about them... However, N. rowanae is simply too different from N. mirabilis, at this point someone should try and explain why they should be put into the same species, because I don't see any reason to do so... As time goes on, some names will get changed and that is a good thing. I don't really see much different between N. densiflora and N. diatas either; the flowers of N. diatas are just as "dense".

Thanks, Crazy Dave Hey Dave, I've been at the herbarium this week and I spent a few hours on the N. thorelii specimens.You're totally right: all the thorelii sheets show an almost completely amplexicaul leaf attachement. It is a very distinctive feature. The species has a strongly decurrent leaf attachement and the wings (1.5-2 cm) are almost touching each other. That's a feature Henri lecomte (the forgotten french man who described N. thorelii and N. kampotiana) had already described well in his latin diagnose. You do have a "great eye" too, Dave;)! François.
