Polyspora

Description from Flora of China

Shrubs or trees, evergreen. Leaves alternate but often clustered apically on branchlets, petiolate; leaf blade leathery, pinnately veined, margin entire or serrate. Flowers axillary, solitary or in a short raceme. Pedicel short; bracteoles 2-7, caducous. Sepals 5, caducous after anthesis. Petals 5(or 6), basally ± connate. Stamens numerous; outer filament whorl adnate to petals; anthers dorsifixed. Ovary placentation axile. Capsule oblong-cylindric or cylindric, 5(or 6-8)-loculed, loculicidal; columella persistent to apex of locules. Seeds flat, apically with an oblong membranous wing; endosperm thin.

Molecular evidence has shown that Polyspora is not closely related to Gordonia J. Ellis, which is now considered to be strictly a New World genus (Prince & Parks, Amer. J. Bot. 88: 2309-2320. 2001; Yang et al., Pl. Syst. Evol. 248: 45-55. 2004).

About 40 species: E and SE Asia; six species (two endemic) in China.
