Note on Two New Additional Plants to Taiwan－Gnaphalium polycaulon Pers. (Asteraceae) and Ipomoea eriocarpa R. Br.

The occurrence of Gnaphalum indicum L. in Taiwan has been questioned. In this paper we confirm the absence of this species and report the presence of G. polycaulon Pers., which had been previously misidentified as G. indicum. In addition, we report a newly naturalized plant, Ipomoea eriocarpa R. Br., in Taiwan. For each species, the taxonomic description, illustration, ecology and habitat information, and distribution map are provided
