We document the naturalization of Flaveria bidentis (L.) Kuntze (Asteraceae) in southern Taiwan. This is one of the many cases of New World plants invading Taiwan. A taxonomic treatment, line drawings, and color photographs of this species from the wild are provided to aid in identification of this alien plant. The colony of F. bidentis was first observed in Taiwan in1987. During our field survey in 2008 we witnessed that the wild populations has adapted to the coast of Chiayi County.
