台灣新歸化繖形科植物-鈎毛峨參

Anthriscus caucalis M. Bieb.-A newly naturalized Apiaceae in Taiwan

摘要


鈎毛峨參(繖形科)原產歐洲,目前廣泛歸化於亞洲、北美洲、南美洲和澳洲。本種果實表面密被捲曲剛毛,在外形上類似竊衣容易混淆,但前者的複繖形花序無總苞片或僅1枚,分果片先端窄縮延長成喙狀,而後者的複繖形花序具4~8枚總苞片,分果片先端不窄縮成喙狀可以區分。本文報導鈎毛峨參歸化於台灣中部中海拔地區的道路邊緣和荒廢地,並提供其形態特性、彩色照片和生育地共同伴生之植物等資料。

並列摘要


Anthriscus caucalis M. Bieb., belonging to the carrot family, is native to Europe and naturalized in Asia, America and Australia. With fruits densely covered by hooked bristles, this species is similar to Torilis japonica (Houtt.) DC., but can be distingulished by its compound umbel without or rarely with one bract, and mericarp with an unarmed short stout beak. In a recent plant survey, a wild population of Anthriscus caucalis was found in central Taiwan. A detailed description with color photographs and habitat information are provided in this paper.
