本研究確認早期臺灣植物文獻所提菊科植物Gnaphalium indicum L. 為多莖鼠麴草(Gnaphalium polycaulon Pers.)，該種自生於臺灣潮濕耕地邊緣；同時報導新記錄旋花科歸化植物毛果薯(Ipomoea eriocarpa R. Br.)。本文描述該二種植物外，並提供形態、解剖圖幅、分佈地與生態資訊。

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 taxsonomic description, illustration, ecology and habitat information, and distribution map are provided.
