Spartina alterniflora Loisel. (Poaceae), a Newly Naturalized and Invasive Plant in Kinmen

金門新歸化之入侵植物－－互花米草（禾本科）

We document the naturalization and invasion of Spartina alterniflora Loisel. (Poaceae) in Kinmen. A taxonomic treatment, color photographs, and distribution of this species from the wild are provided to aid the identification of this alien plant. S. alterniflora is found on muddy banks, usually of the intertidal zone, native to eastern North and South America. This plant was intentionally introduced to China in 1979 for the purposes of erosion check, soil melioration and dike protection and now rapidly naturalized to the intertidal zone of southeastern China. During our field survey in 2008 we witnessed that the wild populations has adapted to the coast of Kinmen. 互花米草（禾本科）原產北美洲與南美洲的大西洋沿岸，1979年曾被中國引種作為促淤造陸和消浪護堤的植種，但現今卻入侵其他沿海地區，嚴重危害當地生態。2008年調查時在金門沿海潮間帶被記錄野外族群，為金門禾本科一新歸化之入侵植物，本屬亦為金門新馴化屬。本報告描述其形態特徵、地理分布及生育地環境並提供彩色圖片。
