A species, B. syzigachne(Steud.)Fern. is found from Guangxi for the first time. There are about 30 species of Tripogon in global, and majority species are distributed in Asia and Africa, including eleven species in China. A species, T. filiformis Nees ex Steud. is found from Guangxi for the first time.
