摘要
Thamnobryum liesneri differs froth all other species of Thamnobryum in its ligulate to lingulate secondary stem and branch leaves that have exceptionally broad (to 160 gm wide and a third or more of the leaf base width), strongly forked and spurred, subpercurrent costae. It differs from all species of Porotrichum and Porothumnium in having leaves with very broad costae and short upper cells. A key to the three species of Thamnobryum in the Neotropics is given.
