Throughout India, Buema, and Ceylon to the Straits of Malacca, ascending 

 the Himalaya to 5000 ft. — Disteib. Mediterranean region and tropics generally. 



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

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

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

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

 coherent joints ; joints of upper (fern.) portion very short and curved callus bearded 

 with brown hairs. Sessile (fern.) spikelets J in. j gl. I coriaceous, glabrous or hispid, 

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

 bracing the long sleUder ovary, tip ciliate ; IT awn stout, column hirsute. PedicelUd 

 spikelets i— J in. ; pedicel very short ; gl. I lanceolate, obliquely twisted, herbaceous, 

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

 miniite, ciliate. SessUe spikelets of the homogamous pairs, like the pedicelled, more 

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

 (excluding poh/stachyus) of this widely distributed plant, founded chiefly on the 

 number and position of the tubercle-based biistles of the male spikelet. They appear 

 to me to be too inconstaut for deiiuition.

 lower 1-3 pairs of spikelets male or neuter with coherent glabrous joints, upper 

 pairs with fragile bearded joints. Ses.nle (fem. or bisexual) spikelets i-i in., callus 

 lObg bearded ; gl. I obscurely 9-nerved, not furrowed dorsally, margins smooth in-
