Ardisia whitmorei Julius & Utteridge sp. nov. (Primulaceae-Myrsinoideae), a member of Ardisia subgenus Stylardisia on account of the style protruding from the closed petals prior to anthesis, is herein described and illustrated as new species. This new species is easily distinguished by the combination of the inflorescences with a slender rachis branched to two orders, the corolla lobes are abaxially glabrous with only two gland-dots near the apex, and the brochidrodromous secondary veins with double loops near the margin.
