台灣新歸化唇形科植物──琴葉鼠尾草

Salvia lyrata L.—A Newly Naturalized Lyreleaf Sage in Taiwan

琴葉鼠尾草（Salvia lyrata L.）（新擬中名）原產美國的東部地區。本種基生葉為蓮座狀排列、單葉羽狀分裂，葉形類似琴形等特徵與台灣的其他種類明顯不同。近年來發現歸化於新北市瑞芳區猴峒道路邊緣荒廢地。本文描述其性狀特性、生育地環境和共同伴生之植物與分布。並報導其花粉為 6 溝花粉，表面具 2 層網狀紋飾。 Salvia lyrata L., belonging to the mint family, is a herbaceous perennial of the Lamiaceae. It is widely distributed across eastern United States. This species is characterized by basal rosette leaves with pinnately lobed or dissected margins. In a recent plant survey, we found a wild population of Salvia lyrata L. in the Houdong area, New Taipei City, northern Taiwan. A detailed description with color photographs, habitat information and distribution are provided in this paper. Additionally, pollen is reported as a 6-colpate pollen grain with a reticulate tectum.
