Abstract:

Two species of the genus Synotis (Asteraceae-Senecioneae), S. rufinervis (DC.) C. Jeffrey & Y. L. Chen and S. kunthiana (Wall. ex DC.) C. Jeffrey & Y. L. Chen, are reported from China for the first time. In China, both species are currently known only from southern Xizang (Tibet). We provide descriptions, illustrations and distributional map in China for the two species. Two important floral micromorphological characters, anther-collar configuration and anther endothecial tissue cell wall thickenings, are also given for the two species.
