Identify this Nepenthes please

[MadAboutCPs]

Hi all,

I would like to know what species or hybrid this Nepenthes is:

Regards,

[Clue]

It's Nepenthes khasiana.

If the leaves behind it (and the pitcher shape really, since no khasiana I have ever seen look like that) are anything to go by, it's not pure khasiana. I know mirabilis x khasiana exists, which would fit this perfectly.

If that's all we go off of, I HAVE seen N. khasiana that look like this! I'm certain it's N. khasiana, but if you really want to be sure you can't base it on the lamina shape alone because N. khasiana is a variable species that looks different in different conditions.

Yeah, N. mirabilis has narrow leaves, but so can N. khasiana. The narrow leaf on my plant was made under lowland conditions, the broader leaves came after I moved it into my highland collection. Yes, I'm also sure that my N. khasiana is not a mirabilis hybrid. Also, the only mirabilis example I have handy right now is making broad leaves but is also certainly just mirabilis (from West Papua, and the species there are distinctive enough that there's no recent introgression in this one judging by the mother plant of this cutting).

The way to be sure is in the leaf bases, N. khasiana has a distinctively broad attachment not seen in any mirabilis.

sorry, inexplicable double post

I know khasiana can have narrow leaves, I know mirabilis can have broad leaves; I have plants of both displaying such at the current moment. I wasn't going off the shape of the leaves alone, but the texture as well, in which the difference can be seen on the plants you posted; khasiana has very waxy/glabrous, shiny leaves, mirabilis either semi-pubescent or at least a visibly rougher, matte texture. The plant shown is somewhere in the middle. As for the pitchers themselves, while there are some exceptions nearly all khasiana uppers I have ever seen form a distinct hip before the upper portion of the pitcher turns at least noticeably if not strongly infundibular, and on those that don't (I reference some photos of wild populations, particularly from the same site as you linked), generally there isn't a strong vein presence as seen in these pitchers which is a very mirabilis-esque trait.
Perhaps there is a chance this is pure khasiana, a clone I have not yet seen anyone in cultivation have, but as it matches exactly the appearance of the hybrid that's still what I am going with.
