Abstract
Ardisia recurvisepala Julius & Utteridge sp. nov. (Primulaceae-Myrsinoideae), a member of Ardisia subgenus Crispardisia on account of the vascularized leaf marginal glands, is herein described and illustrated as new species. The new species can be easily recognized by the elliptic-oblong calyx lobes recurving at the apex, and is also characterized by the narrowly elliptic to narrowly oblong-elliptic leaf laminas with an attenuate-decurrent base and acuminate-caudate apex. Ardisia recurvisepala is known so far from a single locality in Perak and its conservation status is assessed as Vulnerable (VU). An updated key to Ardisia subgenus Crispardisia in Peninsular Malaysia is provided.
