A TAXONOMIC STUDY OF GENUS GYNOSTEMMA BL. AND ITS CONFUSED SPECIES FROM SOUTH CHINA

The present paper deals with the taxonomy of species of genus Gynos-'temma Bl. and its confused species from South China. Genus Gynostemma includes four species in this area, i. e. G. simplicifolium BL, G. laxum (Wall.) Cogn., G. pentaphyl-lum (Thunb.) Makino and G. longipes Wu et Chen. However, there are eight species confusing with species of Gynostemma, i. e. Hemsleya chinensis Cogn. ex Forbes et Hemsl., H. amabilis Diels, H. sphaerocarpa Kuang et A. M. Lu, H. dipteriga Kuang et A. M. Lu, H. graciliflora (Harms) Cogn. belonging to Cucurbitaceae, and Tetrastigma hemsleyanum Diels et Gilg., Cayratia japonica (Thunb.) Gagnep. and C. japonica (Thunb.) Gagnep. var. pubifolia Merr. et Chun belonging to Vitaceae respectively. The appropriate identification of species may be of value to utilization of these Chinese medicinal plants. A key and brief accounts of the species are provided in the text.
