Since 2013, N. alata has been split into several taxa. I think that's still work in progress. Most plants spread as N. alata in the last decades had no location of origin, so they can't be identified based on that. They were often single clones, and it's hard to identify similar species on the base of one specimen only. Plus, some of the new taxa that N. alata has been split into could turn out to be synonyms, so just consider this page to be about the "N. alata group". In red, my ID attempts.


BE3001

Sex: single clone.

Origin: Mt Guiting-Guiting, Sibuyan, Philippines, 60 m.

Notes: discovered in 1996 by Cantley, this is assumed to be Nepenthes alata, but somewhat different and may be an as yet undescribed species. It was sold as a single clone since Oct 2009. It was previously sold in 6 clones as BE3001 and BE0060. Photo by Ch'ien Lee.

EPe

EPf

Sex: female.

Origin:

Notes: N. graciliflora. This is the clone nicknamed var. boschiana or "boschiana mimic". Mostly red lowers, wide mouth, bulbous base, intermediate. It seems the nickname derived from a mislabeling at Longwood, where the mother plant was labelled "N. boschiana". From there, its clones have travelled across the world, in all private and public collections. Photo by Avery.
