ERODIUM CIUTARIUM (L.) L'HERIT. (GERANIACEAE)A NEWLY NATURALIZED PLANT IN TAIWA

芹葉牻牛兒苗-台灣新歸化牻牛兒苗科植物

摘要


Erodium cicutarium (L.) L'Herit. (Geraniaceae) originating in Mediterranean Europe is here reported for the first time from Taiwan. This newly naturalized species differs from E. moschatum (L.) L'Herit, first recorded in Taiwan in 1992, by having deeply cleft leaflets and pointed sepals with an apical extension of the midrib. The taxonomic treatment of E. cicutarium and a key to species of Erodium in Taiwan are given in this study.

本篇報告描述原產於歐洲地中海地區的牻牛兒苗科植物「芹葉牻牛兒苗」首次在台灣花蓮縣關原發現。此新歸化種不同於1992年首次在台灣發現的新歸化植物麝香牻牛兒苗,主要差異是芹菜牻牛兒苗的小葉羽片深裂且萼片頂端銳尖具芒。此種之分類處理和台灣的牻牛兒苗屬(Erodium L'Herit.)簡索表亦列出,以資辨識此兩種台灣新歸化種。
