Abstract: The purpose of the present paper is to discuss the relationship and geographic distribution of the species of the genus Glechoma Linn. and its relationship with other genera in the Nepeteae.Moreover,it is a very typical Laurasian genus that is closely related to genera Suzukia Kudo,Phyllophyton Kudo,Meehania Britt.ex Small et Vaill.,and Nepeta Linn.;especially Suzukia Kudo and Phyllophyton Kudo,which are derived from Glechoma Linn.,but apparently Glechoma itself is probably derived from Meehania Britt.ex Small et Vaill., at the same time taxa will be supplied a good representative of the evolutionary tendencies of northern temperate flora.

Key words: Eurasian -genus -allied

摘要： 活血丹属（Glechoma Linn．）中的一些植物，是欧亚大陆民间常用的药草，为人们所熟悉，有一定的经济价值。同时，在探寻这一群植物的属间关系和起源方面，也很有意义。属的中文名称，是根据我国江南一带常见的植物——活血丹〔G．lonaituba（Nakai）Kupr.）而来，由于主要用于活血舒筋而得名，出自江西九江一带，还有马蹄草、透骨草等植物，也是本种的同物异名。
