Nepenthes berbulu (Nepenthaceae), a pitcher plant from Peninsular Malaysia with remarkably long lid bristles

Abstract

A species of Nepenthes endemic to Peninsular Malaysia and distinctive for its extremely developed lid hairs is described and illustrated. Nepenthes berbulu is a highland species known only from a handful of peaks in the Titiwangsa Range. It is classified here within the recently defined N. macfarlanei group, for which a dichotomous key is provided. The description of this taxon brings the total number of Nepenthes species recognised from Peninsular Malaysia to eighteen.
