Abstract:

Camchaya Gagnep.，a genus of the tribe Vernonieae，Asteraceae，was newly recorded from Guangxi，southern China. We provided a taxonomic description，detailed photographs of the only one representative species C.loloana Kerr，a distribution map of the whole genus. This finding indicated the close floristic affinity between southern Yunnan，Indo China Peninsula and the tropical areas of southwestern Guangxi.
