Abstract： Centratherum Cass., a newly naturalized genus of the family Asteraceae from Southeast Asia, was recorded in northern Thailand and southwestern China. Centratherum punctatum Cass. subsp. fruticosum (S. Vidal) K. Kirkman ex Shih H. Chen, M. J. Wu & S. M. Li, the only one representative subspecies of this genus from mainland of Southeast Asia, is described and illustrated based on the specimens. C. punctatum subsp. fruticosum can be distinguished from the other taxa of this genus by its leaf blade rhombic to elliptic, leaf margins irregularly serrate, leaf apex broadly acute, and phyllaries indurate at base and not awned. Its distribution map is provided and the possible dispersal pathway is discussed.
