Nepenthes barcelonae (Nepenthaceae), a new species from Luzon, Philippines
Martin Cheek, Danilo N. Tandang, Pieter B. Pelser

Abstract

Nepenthes barcelonae is described as a new species in sect. Insignes, where it is unique in the inset mouth and the dichromic upper pitchers (first-produced pitchers red, later-produced pitchers green) which are also dimorphic. This is a newly recorded phenomenon in the genus: the first produced (primary upper pitchers) are red, larger, stouter, and have an uncoiled long tendril, while those later produced (secondary upper pitchers) are green, smaller, more slender, and have a coiled tendril. The only population of this species that is currently known grows in an area less than 10km² on a single mountain. Individual plants are at risk from collecting for the horticultural trade. Following the IUCN criteria, N. barcelonae is assessed as Critically Endangered.
 
Interesting, especially the note about the upper pitchers. Will see if my uni has full access to the article on Monday.
 
Wish they had a picture id be interested in seeing what it looks like
 
Sounds cool! Wow, two stage upper pitchers… Who knew?!
 
Interesting description on this plant. :pics: anyone?
 
Write to one of the authors and perhaps they will send you a copy of the article. Or subscribe to Phytotaxa (at $2600 a year) and download a copy.
 
Here's a link to a fairly comprehensive overview (plus pictures!) of N. barcelonae from François Mey's blog. Before the pictures came out, I was wondering whether or not N. barcelonae was conspecific with a Nepenthes species from Mt. Mingan (that's been creatively called "N. sp. Mingan"), but there was a listing on Leonardo Co's website listed the two as separate species. Now, the list has been edited (the taxon from Mingan being removed)... I can't confirm it, but if they are the same species, N. barcelonae is already in cultivation.

Another one for the N. ventricosa complex...

Thanks for the link and information.

According to François Mey, N. barcelonae is in fact the Insignes Nepenthes from Mt. Mingan.

These are quite a ways away from the "dimorphic" uppers mentioned in the paper, but here is a picture of a couple of my seedlings.

Awesome Dex, it's interesting how the edges of the leaves are rather hairy, vent and sib leaves and smooth and hairless on the edges.

I think that's actually an N. attenboroughii seedling.

There are already images available and also some disagreement about its initial description, in terms of the color of the upper versus lower pitchers -- whether they even exist in terms of differences; whether those green leaves will eventually change to red . . .

"The point on the dichromy of upper pichers is debatable. The primary pitchers being red and the secondary being green is not on agreement with their own observations. The green pitchers actually turn red. While Cheek, Tandang & Pelser's paper insist that N. barcelonae doesn't produce lower pichers, as it seems to be the case with other members of the Insignes section, Robinson and his colleagues find out that lower pitchers are produced but in very young plants and they do exhibit wings albeit dimished ones. Actually, what Cheek et al. see as primary upper pitchers would be better off seen as rosette pitchers lacking wings with unusual pitcher insertion (this is not new in the genus) . . ."

Man I hope it's an N. attenboroughii seedling. None of my N. attenboroughii have grown anywhere as quickly as these seedlings have. I am 99% sure this is N. barcelonae

Some other examples of seedlings:
