Bot. 16:692. 1940. [Description] Branchlets pubescent. Leaves ovoid, bases rounded, somewhat pubescent. Flowersshort pedicelate, bracts 4-5; sepals 5, ovoid, pubescent; petals pubescent, apices 3-cleft. Capsules 3-locular, sometimes 1-2-locular. The Taiwan specimen has membranous leaves. Among the Guangdong specimenssome also have membranous leaves and are very similar to C. salicifolia. These plants differ from the typical C. cordifolia which hasleathery leaves, and this may indicate somehybridization between these two species. [Distribution] Guangdong, Guangxi, Jiangxi, Taiwan, Hunan. [Synonym] Thea cordifolia Metc., Lingnan Sci.
