台灣紫草科的新紀錄植物──野勿忘草

Myosotis arvensis (L.) Hill (Boraginaceae), a Naturalized Species in Taiwan

本文報導最近在台灣東北部發現原產於歐洲之新紀錄種──野勿忘草（Myosotis arvensis (L.) Hill）。對台灣而言，此發現是新紀錄屬亦是新紀錄種。勿忘草屬與附地草屬相似，但以其平且光滑、雙凸鏡形之小堅果，而與後者以及台灣所產紫草科其他屬皆不同。本文提供屬及種之形態描述、彩色照片及繪圖。

Myosotis arvensis (L.) Hill (Boraginaceae), a species native in the Europe, was naturalized recently in the northeast Taiwan. The introduction of M. arvensis adds a new element for both the genus and the species to the floristic composition of this island. Myosotis closely resembles Trigonotis, but can be easily distinguished from the latter and other genera of the Boraginaceae by having smooth and biconvex nutlets. This paper provides description of the genus and the species, line drawing, and color photos.
