march. 1907. j ENUM. PL. FORMOSANARUM. 53 



Distrib. Western Himalaya at an altitude of 2100m. 



This Agrosts is very like A. canina of the northern part of 

 Japan. But my Morrison specimen has no awn and of course 

 it must be different from A. canina. Besides, in my specimen, 

 glume I. and II. are narrow and more acuminate and gl. III. 

 is much shorter. Hooker's description of A. Clarkei quite agrees 

 with my plant.

This new species much resembles B. unioloides in the form 

 of its spikelets, but differs from it by the longer and more 

 branched panicle, and still more by the filiformed leaf.
