Abstract

Cleyera bokorensis Nagam. & Tagane (Pentaphylacaceae), from Bokor National Park in southern Cambodia and Binh Dinh Province, central Vietnam, is illustrated and described as new. Cleyera bokorensis is a rheophytic shrub characterized by oblong-elliptic leaves with sparsely and obtusely serrate to serrulate margin, 7–10 pairs of secondary veins, solitary flowers, a 1.6–2.7 cm long pedicel and 6.5–10.5 mm long petals. The combination of features clearly distinguish it from C. japonica and other species of Cleyera in Indochina and surrounding countries.
