澤珍珠菜於台灣消失123年後的再發現

Rediscovery of Lysimachia candida Lindl. (Primulaceae) in Taiwan after 123 years

澤珍珠菜（Lysimachia candida Lindl., Primulaceae）廣泛分布於中國大陸、日本、緬甸及越南等地，但未曾記載於台灣植物誌等叢書。2012年澤珍珠菜獲報導為台灣之新紀錄植物，但同時也被宣告區域滅絕，因在1897年後此物種便在台灣便無任何標本紀錄。最近，我們於基隆巿一開闊的草生地上採集到本種，故於本文報導澤珍珠菜於台灣消失近123年後的再次發現，並提供本地族群之形態特徵資料。

Lysimachia candida Lindl. (Primulaceae) is widely distributed in East Asia (Mainland China,Japan, Myanmar and Vietnam) but has not been recorded in two editions of Flora of Taiwan. In 2012, thisspecies was reported as an extinct newly recorded species of Taiwan, which does not have any record since1897. During our recent field work, we rediscovered a population of L. candida on grassland in KeelungCity, and thus we report here its rediscovery in Taiwan after nearly 123 years and provided morphologicaldata based on its local population.
