本文訂正臺灣之水冠草屬(Argostemma)植物。僅確認水冠草(A. solaniflorum Elmer)一種。臺灣水冠草(A. taiwanese Ying)處理為水冠草之異名。水冠草在臺灣僅分布於蘭嶼,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. solanifl orum. This species is reported for the first time from Taiwan proper and it possibly reached there through wind-disperdsal.
