T. Anderson subsp. micrantha (Nees) Ensermu, an Acanthaceae species native in Africa, India and Sri Lanka, has been recently found naturalized in the southern Taiwan. The naturalization of A. gangetica subsp. micrantha adds a new element to the flora of this island. Asystasia is easily distinguished from other genera of the Acanthaceae by corolla being zygomorphic, 4 stamens, 4-seeded and distinctly stipitate capsule. A. gangetica subsp. micrantha is characterized by ovate to oval leaves, and white flowers. This paper provides description of the genus and species, line drawing, and photographs.
