AbstractA taxonomic revision of Sageretia lucida, S. thea var. cordiformis and S. yunlongensis in China is presented. Sageretia lucida is revised in terms of morphological characters (habit, branchlet color, phyllotaxis and rachis length), distribution, habitat, and phenology; S. thea var. cordiformis is raised to S. cordiformis; and S. yunlongensis is excluded from the genus Sageretia and reduced to the synonym of Rhamnus nigricans. Furthermore, a new species, S. ellipsoidea, is erected based on the paratype collections of S. lucida. The new species morphologically differs from S. lucida in having reddish brown branchlets, opposite or subopposite phyllotaxis, shorter rachises, and flowering in spring or early summer. S. ellipsoidea is factually closest to S. hamosa as they share similar woody-vine habit and larger fruit size, and fruiting in winter, whereas the former can be easily recognized based on its smaller leaf blades, fewer lateral veins, shorter rachises, and ellipsoidal or elliptic-ovoid fruits.
