 Collett. DISTRIB. Afghanistan, S. Africa. 



Stems tufted, 1-3 ft., simple or branched, usually almost filiform, rarely as thick 

 as a crow-quill or stouter. Leaves 6-18 in., rarely more than in. broad, finely 

 acuminate, quite smooth above and beneath, margins minutely scaberulous ; upper 

 sheaths terete, lower more or less compressed, sometimes very much so and mem- 

 branous. Panicle 2-4 in., rarely more ; rachis flexuous ; branches in whorls of 

 3-12, rarely more, smooth or scaberulous, lowest -1 in. or more, upper shorter ; all 

 quite smooth, or in the lower part together with the rachis scaberulous, rarely 

 scaberulous throughout. Spikes very variable in size ; the green blue and purplish or 

 brown pedicelled always longer than the pale sessile. Sessile spikelets |-^ in. ; 

 callus hairs short or long, from white to rusty red ; gl. I narrow, strongly com- 

 pressed, margins membranous, tip rounded ; II broader, tip 2-fid, with a short 

 recurved awn, keel obtuse from glabrous to hirsute for a greater or less part cf its 

 length, with rigid or flexuous rufous or white bristles, margins membranous hardly 

 ciliate; III hyaline, oblong, obtuse, ciliate ; IV the long narrow hyaline 3-nerved 

 eciliate dilatation of the awn. Pedicelled spikelets -5 in., neuter or male, from 

 ovate- to linear-lanceolate, acuminate ; pedicels cuneate, margins sparsely or densely 

 villous, the upper hairs in some of the most densely villous nearly equalling the 

 spikelet from dark rusty red to white ; gl. I thin, acute acuminate or awned, the 

 awn equalling or shorter than the gl., glabrous or pubescent; nerves always 7, sub- 

 equidistant, or 2 on each side sub-carinal ; margins narrowly incurved, spinulosely 

 ciliate or smooth; II lanceolate, acuminate, ciliate; III hyaline, oblong, obtuse, 

 2-nerved or nerveless ; IV shorter, narrower, hyaline, 1-3-nerved. I am unable to 

 classify the varieties of this common and variable plant in accordance with 

 geographical areas or other considerations. This, if possible, must be effected by 

 field botanists in India. There is every gradation from the coarsely hirsute keel df 

 monticola, to the perfectly smooth of some states of Trinii ; from the awuless to 

 long awned gl. I of the pedicelled spikelets, and from the glabrous to the pubescent 

 of the same organ ; the colour of which affords no character ; nor does its length, 

 or that of the cilia on its keels.
