Abstract

Memecylon longipedunculatum, a new species of Melastomataceae, is described and illustrated. The species is known to occur in Khanh Hoa and Ninh Thuan provinces in South Central Coast Vietnam, where it is restricted to low dry coastal forests and scrubby vegetation. The description is based on the authors’ original gatherings as well as on the historical collections made a century ago. The new species is distinguishable from most of its congeners by small leaves (1.2–5.7 × 0.7–2.4 cm) with obtuse or sometimes emarginate apices, long peduncles (1–2.7 cm long), and crescent-shaped anther connective with distinct centrally placed gland.
