台灣植物誌之觀察（27）──水冠草屬（茜草科）

Notes on the Flora of Taiwan (27)－The Genus Argostemma Wall. (Rubiaceae)

本文訂正台灣之水冠草屬（Argostemma）植物。僅確認水冠草（A. solaniflorum Elmer）一種。台灣水冠草（A. taiwanense Ying）處理為水冠草之異名。水冠草在台灣僅分布於蘭嶼，本文首次報導其亦出現於花蓮嵐山海拔約1,900公尺處，並認為可能是經由風傳播而來。

The genus Argostemma in Taiwan is revised. One species. A. solaniflorum Elmer, is recognized. A. taiwanense Ying is treated as a synonym of A. solaniflorum. This species is reported for the first time from Taiwan proper and it possibly reached there through wind-dispersal.
