THE GENUS TYPHONIUM (ARACEAE) IN TAIWAN

A taxonomic revision of the genus Typhonium (Araceae) in Taiwan is pro vided in this paper. In addition to Typhonium blumei Nicolson & Sivada san (as T. divaricatum), the only species previously reported from Tai wan, we report our discovery of a second species, T. roxburghii Schott , from southern Taiwan. The latter is easily distinguished from the fo rmer in having broader leaves and slightly decurved sterile flowers. I t was possibly unintentionally introduced and naturalized recently. A key to the species along with a description, taxonomic notes, a line d rawing, and a photograph is provided.
