A densely tufted grass, 1-3 ft. high, with fibrous roots; 

 stems slender, quite smooth; 1. 4-10 in., very narrow, acumi- 

 nate, glabrous, slightly scaberulous, sheaths smooth, ligule 

 erect, oblong, scarious, variable in length ; panicle 4-6 in. long, 

 erect, effuse, ovate, lax-fid., rhachis and capillary spreading 

 branches smooth or faintly scaberulous, lower branches 

 whorled, upper opposite, pedicels longer or shorter than the 

 spikelets, capillary; spikelets -— m - l° n g; glumes I and II, 

 subequal, ovate, acute, keeled, glabrous, midrib strong, veins o, 

 III \ shorter than II, tip truncate, erose, ciliate with long 

 hairs, veins 4 and a very short median terminating in a geni- 

 culate awn a little above the base, callus hairs short, awn about 

 twice as long as the spikelet, palea half as long as its glume, 

 oblong. 



Central Province, alt. 6000-8000 ft. Spikelets green or purplish. 



Himalaya and Nilgiri Hills. 



In Fl. B. Ind. I have selected pilosula as the earliest name which 

 I could confidently accept for this plant. The Agrostis Royleana of 

 Trinius (C. Royleana, Steud) was founded on a plant with a 5 bearded 

 continuation of the rhachilla,' which would place it in Deyeuxia; and 

 Cal. Hookeriana, Steud., is described as having the palea as long as its 

 glume, which I have not found to be the case in any specimen of the 

 Ceylon plant, or in any Indian species of the genus.

awnless, fig. glumes all bisexual or the uppermost male or
