COLONEL MUNRO'S MONOGRAPH OF THE BAMBUSACE.E. 25 



The foliage of this plant is used at Newera Ellia as a fodder for horses (Thw.). The 

 length of the glumes at once distinguishes this from A. distans, which in some respects 

 it approaches.

 hirsuto-pubescens, (dempto acumine) superiorem fere enervosam obtusam inter carinas apice tantum 

 hirsutam vix superans. Squamulce subaequales, obovatae, obtusae, longe fimbriatae. Stylus cito bifidus 

 in stigmata 2 longa basi nuda apice pennata. Ovarium infra stylum constrictum. 



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

 inflorescence it approaches A. debilis, 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 Chttsquea.

vaginis ssepissime superne viscosis ore longe fimbriatis, paniculae terminalis com- 

 positae ramis sublongis demum refractis, spiculis lieterogencis 6-12-floris, glumis
