Nepenthes bokorensis

[eboat]

Hi all,
How do you ID bokorensis from kongadana and thorelii???
Do you have a keys of this species?

Thanks

Hi eboat,

If you give me your mail, I can send you the pdf of the whole description.

I didn't treat N. kongkandana in my work because it is not described yet but I have compared N. bokorensis with N. kampotiana, N. smilesii and N. thorelii.

I remind everyone that the real thorelii has not been officially re-discovered (since 1909!) and it is very unlikely that is in cultivation.
All the so-called "thorelii" are either N. smilesii, N. bokorensis, N. kampotiana or undescribed taxa such as N. kongkandana, the "tigers" or, worse case, hybrids between all those related species!


Here is an extract of the description of N. bokorensis:

2. Putative relatives. Nepenthes bokorensis is closely related to N. kampotiana, N. smilesii and N. thorelii, but differs from all of these species in that the leaf is much broader and also more oblong in shape. The occasional production of 2-flowered partial peduncles is also unusual in this group of species. It may also be distinguished from N. kampotiana as the foliage of that species is typically glabrous, whereas in N. bokorensis most parts of mature plants are usually lined with short hairs. Nepenthes bokorensis may be distinguished from N. smilesii by its pitcher morphology; the pitchers of N. smilesii are narrow, with a thin peristome, less colouration and shorter tendril than those of N. bokorensis, which are broad and have a characteristically robust peristome. Nepenthes bokorensis differs from N. thorelii by the attachment of the leaf to the stem; in N. bokorensis, the lamina is sessile to sub–petiolate and clasps the stem, only ever becoming slightly decurrent, whereas in N. thorelii the lamina is nearly completely amplexicaul and strongly decurrent. N. bokorensis may also be distinguished from N. thorelii by its pitcher morphology: the lower pitchers of N. thorelii are ovate whereas those of N. bokorensis are ovate in the lower third and cylindrical in the above. Nepenthes bokorensis is unlikely to be confused with these three species in the wild and it is not known to occur sympatrically with any of them. Therefore, no natural hybrids including N. bokorensis as a parent species are known.
