I've just read in Flora Malesiana (vol.15, 2001) by Jebb and Cheek that these two authors kept N. copelandii as a synonym of the variable N. alata, although they did consider to split them because of a slight difference of the flower structure, indumentum and gland distribution (in fact they wanted to wait for more researches). Does someone know of a later scientific paper (ie after 2001) which has separate N. copelandii from N. alata?
It seems that this taxon is widespread in culture and that nursery (wo)men and hobbyists treat it as a good species.
My question is not to know your opinion on the taxonomic treatment of N. copelandii (but we can discuss about this ;D) but to know if someone has validated N. copelandii as a good species after Jebb and Cheek 2001 work.

The species was named in 1908. Since then, no convincing evidence has come to light indicating it should be combined into N. alata. Infact, the direct quote is, "Nepenthes copelandii may also deserve restoration, but further study is first needed. It seems distinct from N. alata on the basis of its 2-flowered pertial peduncles, hairy stem and sparse lid glands. It appears restricted to non-ultramafic areas of Mindanao and adjoining islands."
Now, I don't really understand the part about "adjoining islands", but not growing on ultramafic soils I understand. Still they do not present any evidence supporting the idea it is part of N. alata, but mentions details indicating they are not the same. And I can personally add the upper pitchers are completely divergent, check out the photos in this thread:
I'm very interested in learning more about the three mountain locations where it grows. What other species occur in these places? I have heard it is found along with N. alata, but I have not been able to comfirm/dispute this yet.
