i got this plant as a cutting from a well known and experienced grower. he said he received it from EP but all he can remember about it is that is N. alata. ive had it verified that it is alata by several people also, but im wanting to get the name of the specific clone on it. EP doesnt have any alata for sale so i cant go through and check. if ANYONE has a plant that looks like mine and it is alata from EP say something and post a pic if you can. its actually really been bugging me that i dont know exactly what it is. pardon the picture quality as it was taken with a phone. the full plant is the vining one behind it.   btw this is the only plant ive been able to closely compare it too. only one pic. and its Sunbelle's i101.photobucket.com/albums/m61/sunbelle451/PICT2418.jpgThanks, Alex |

Looks like it is one of the hairy alata's from Luzon... I don't think your plant falls into a named variety or known location.
It is very interesting to note the wings are reduced to ridges and they are also fairly close together, like in N. albomarginata. Also, the stem/leaf attachment is completely non-amplexical in the upper growth.
So... Does your plant have hairs on it, especially the lower growth?

The slightly wavy peristomes tell me something's not quite what it should be...

Dave: it has a lot of hair. The stem, tops of leaves, leaf margins, tendrils and pitchers are covered in a semi dense but very low lying hairs. The hairs are clear and I mean semi dense as in the hairs are all over but they don't overlap eachother.
Ayi: this is the first time the peristome has been wavey like this.

uh-oh... If it has hairs then it MIGHT be the "real" Nepenthes alata (you see, there is another entity from the Philippines which look like N. alata, and it's been called as such, but there are no hairs on the plant). What concerns me is the absence of fringed wings on your plant- this absence is characteristic of the alata look-alikes.
For more info on this matter, do check out the threads regarding N. alata in the Philippines section...

Hello Ayi,
Don't be too concerned, Nepenthes do show variation... For one thing, it appears all the fringe elements have been completely suppressed, on the glabrous alata plants the wings are half and half for the most part. Seeing completely suppressed wings on the hairy alata doesn't actually break the pattern, it just confirms that like most other species, the upper pitchers can have wings which are reduced to ridges.
Any chance this plant could be a horticultural hybrid?

Dave: the only thing I know about this plant is that it was an extra in an EP order. He said it came as N. alata and a clone number or something similar but that was lost. What do you mean by a horticulture hybrid? Man made for select attributes? Would it be encouraged to ask EP for their opinion?

Just wondering... If no recalls crossing the two kinds of N. alata, it is probably just an example of the hairy taxon. Jebb and Cheek's version of N. alata; as well as McPherson's, appears to be a mixture of two species... I've written a condensed version of the story here: www.rci.rutgers.edu/~dpevans/Nepenthes/N_alata.htm |

I've written a condensed version of the story here: www.rci.rutgers.edu/~dpevans/Nepenthes/N_alata.htmDave, The problem here is in the fact that this particular plant originally came from Kew Gardens in the UK, and was labeled in Longwood Gardens as N. burkei; however, no known population of these plants have since been found, along with the other "N. alata red form" they had which was called " N. stenophylla", which was similar, but had a vaulted lid; both seemed to grow best in highland conditions with a diurnal shift in temperature, with a much cooler night time drop in temps. Also, BOTH plants are female. - Rich |

While the same exact plants have not been found again, or at least not identified as such, the taxon has been found again: photo by Delphiguy from "The alatas" thread:  |

Hi Dave,
I have never seen a hairy alata with wings reduced to ridges. In fact, all known N. alata I have seen (whether personally or in photos) have their upper pitchers decorated with fringed wings. Or am I missing something here?
Two things: the plant before us may either be a hybrid, or a hitherto unknown variation of N. alata.
Hi glider14,
I know this might sound too complicated for you, but could you please check out the lid glands on your plant? Do take note if they are volcano-like, or just like pits, and whether they have borders or none at all, if they are distributed all throughout the lid undersurface, and if they all look the same (monomorphic).

Thanks for all the input guys. Yea I really don't understand everything. Haha. When I go home next I'll check on the glands for you. From what I remember the glands are in fact pits. But other than that my memory doesn't hold. I'll update this thread here in like two weeks.
Alex

Your plant indeed seems to be the real Nepenthes alata. What is amiss though is the degenerated wings. In 'real' alatas the wings are fringed. Then again there is the possibility of your plant being a hybrid. What is difficult to pin down is to which species.
