COLONEL MUNRO'S MOInOGRAPH OF THE BAMliUSACEvE. 25 



The foliage of tins plant is iisod at Newera Ellia as a fodder for horses {Thic). The 

 length of the glumes at once distinguishes this from A. distaus, Avhich in some respects 

 it approaches.

I have seen only the upper portions of the stem of this plant. In the style of the 

 inflorescence it approaches A. debil/s, Thw. ; but from this and all other species of the 

 genus it is readily distinguished by its extremely narrow leaves and very long points to 

 the glumes. In this latter respect it resembles several species of Chusquea.
