The genus Lepisanthes Blume (Sapindaceae Juss.) has 24 species distributing in tropical Africa, Madagascar, S and SE Asia from Sri Lanka to Hainan (China), Malesian area and NW Australia. According to Pierre (1895), Lecomte (1912), Gagnepain (1950), Pham Hoang Ho (2000), Tran Kim Lien & Ha Minh Tam (2003)..., in Vietnam, the genus Lepisanthes have 6 species: Lepisanthes amplifolia (Pierre) Leenh., Lepisanthes banaensis Gagnep., Lepisanthes fruticosa (Roxb.) Leenh., Lepisanthes rubiginosa (Roxb.) Leenh., Lepisanthes senegalensis (Poir.) Leenh. and Lepisanthes tetraphylla (Vahl) Radlk. During the study of the specimen Vu Dung 36 collected in Gialai province (Ankhe), we have identified that it is Lepisanthes unilocularis Leenh., a new record for the flora of Vietnam.
