Throughout India, Burma, and Ceylon to the Straits of Malacca, ascendmg 

 the Himalaya to 5000 ft.— Disxrib. Mcditerraueau region and tropics generally. , 



Stems 1-5 ft., erect or decumbent below, densely tufted, simple or fastigmtely 

 branched, compressed towards the base. Leaves 6-18 in., narrow, glabrous or hairf 

 especially near the base, rather glaucous, rigid, margins and upper surfaces scabna ; 

 sheaths compressed, keeled. Sollies with the lower 2-6 pairs of spikelets male with 

 coherent joints ; joints of uppor (fern.) portion very short and curved callus beard^ 

 with brown hairs. Sessile (fern,) spikelets i in. ; gl. I coriaceous, glabrous or hispid^ 

 many-nerved, tip membranous; II coriaceous, 3-nerved; III oblong, hyaline, em- 

 bracing the long slender ovary, tip ciliate ; IV awn stout, column hirsute. F^'dxcelU^ 

 siiJceleU \-^ in. ; pedicel very short ; ^1. I lanceolate, obliquely twisted, herbaceous, 

 keels margined or unequally winged ; II membranous, acute, 3-nerved, ciliate; pii 

 minute, ciliate. Sessile spikelets of the homogamous pairs, like the pedicclled, vio 

 or less covered with tubercle-based hairs.— Hackel has 2 varieties and 5 subvanetie* 

 (excluding pol^stachyus) of this widely distributed plant, founded chiefly on tue 

 number and position of the tubercle-based bristles of the male spikelet. They appea 

 to me to be too inconstant for definition..
