 ^-5 in., ovate or elliptic, acuminate, membranous, very sparingly hairy 

 or nearly glabrous, base slightly auricled, margins naked or sparsely 

 ciliate especially towards the base ; sheaths short, glabrous ; ligule 

 small, hyaline. Panicle of 3-5 slender branches ; rhachis capillary ; 

 internodes shorter than the slender spikelets, usually ciliate with long 

 erect hairs (rarely glabrous). Spikelets solitary (rarely with a pedi- 

 cellate one), ^ in. long, narrowly lanceolate ; callus nearly glabrous. 

 Glumes 4; lower invol.-giume thinly membranous, lanceolate, 2-cuspi- 

 date, 5-7-nerved above the middle, the nerves usually seabrid ; upper 

 invol.-glume as long as the lower, narrowly lanceolate, narrowing out 

 into a very fine awn-like point Ju~3V ^"- ^°"o ' ^o^^'*^^" floral glume much 

 shorter than the upper invol.-glume, lanceolate, acuminate, epaleate ; 

 upper floral glume -j^q in. long, ovate-lanceolate, subacute, hyaline, with 

 an awn about f in. long from near the base, the column of the awn

 or many, on long naked or spathaceously sheathed glabrous peduncles, 

 l)ale green or purplish. Spdvelets ^~l in. long, lanceolate or linear- 

 lanceolate ; callus naked or shortly bearded. Glumes 4; lower invol.-

A very variable species of wiiich Ilackel (Monog. Andropog. p. 3.'J4) recognizes no 

 less than 12 forms. Tlie.se, however, for the Indian speeies Sir Josepli Hooker has 

 reduced to four. Tliere is only one specimen from Bombay in Herb. Kew. , obtained 

 by Ritchie from Belgauni, and ttiis has been included by Sir J. Hooker in his group 

 Violaceas.
