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.
