Abstract

Bromus commutatus Schrad., which was misapplied as Bromus secalinus L., was annotated. The occurrence of Ischaemum timorense Kunth. on the Lanyu Island, off the southeast coast of Taiwan was confirmed for the first time. Spartina alterniflora Loisel., an alien grass to the flora of Taiwan, was naturalized in central Taiwan. Descriptions, illustrations, and a distribution map of these three grasses were offered.

中文摘要

本文訂正日前歸化的禾草：歐雀麥 (Bromus secalinus L.)，應為Bromus commutatus Schrad.的鑑定錯誤；此外，確認近日於蘭嶼尋獲的禾草：帝汶鴨嘴草 (Ischaemum timorense Kunth)；以及臺灣中部新歸化的外來種禾草：互花米草 (Spartina alterniflora Loisel.)，文中提供這三種禾草的描述、線繪圖及分布圖。
