Well, the species is a straightforward _Nepenthes_. The seeds,
however, do not have the long "tails" on either side of the embryo
that are so characteristic for the other species in the genus (Greek:
An-=non-; uro=tail; sperma=seed). This has been interpreted as an
adaptation to life on small islands (Seychelles), where long thin
seeds could possibly be blown away to the open sea.
Kind regards
