Abstract

Ardisia ledangensis Julius & Utteridge, a new species from Gunung Ledang, Johor, in the southern part of Peninsular Malaysia, is formally described and illustrated. Its placement within subgenus (§) Crispardisia is justified by diagnostic characters such as vascularised glandular nodules along the leaf margin and a terminal inflorescence borne on a lateral shoot, accompanied by a normal foliage leaf (rather than a reduced, bract-like leaf). The species is distinctive among Peninsular Malaysian members of the subgenus by its slender, descending habit, narrowly elliptic leaves densely covered with black glandular-dots, and unbranched, strictly terminal inflorescences. Ardisia ledangensis is known only from a single locality within a protected area, and its conservation status is provisionally assessed as Least Concern (LC).
