The new species Polyalthia zhui X. L. Hou & S. J. Li, found from Hainan and southern Guangdong in southern China, is described and illustrated. It has previously been confused with Polyalthia nemoralis A. DC. or R littoralis (Blume) Boerlage in China, but is distinguished on the basis of its green fleshy ovate petals, outer petals spreading ca. 4 x 2.5 mm, inner petals not fully spreading, somewhat bent to the inside, ca. 5-6 x 4-4.2 mail 1. mm thick or more, its carpels pilose only in the lower half, and its non-lobed stigma.
