Abstract
Ardisia gasingoides Julius & Utteridge sp. nov. (Primulaceae-Myrsinoideae) is described and illustrated as a new species; it is endemic to the state of Johor from southern Peninsular Malaysia. The new species belongs to subgenus Stylardisia and is morphologically similar to Ardisia cockburniana, A. crassa and A. crassiuscula in having obconically flared and thickened pedicels but differs in smaller leaves with fewer veins, few flowers in shorter inflorescences and, especially, the 5-sided turbinate fruits. A preliminary conservation status and key to related taxa are provided.
