This is a perennial grass. 



The stems are usually slender, densely tufted, erect, simple, or 

 branched, leafy especially at the base, varying in height from I to 

 3 feet. 



The leaf-sheaths are sparsely hairy or glabrous, the lower some- 

 what compressed and the upper terete. The ligule is a short, 

 ciliated membrane. The nodes are glabrous. 



The leaf-blade is narrow, linear, acute, rigid, fiat, glaucous, 

 smooth or scaberulous, with margins scabrid and ciliated with 

 tubercle-based hairs especially towards the base, and varying in 

 length from 2 to 15 inches. 



The inflorescence is an open panicle, ovate or oblong, varying 

 in length from 2 to 5 inches ; the rachis is slender, smooth or 

 scaberulous, the branches are capillary, whorled and spreading, 

 tip oblique, bearded and bearing a single sessile and two pedi- 

 cellate spikelets.

I. Sessile and pedicellate spikelets ; ?, 3, 4 and 5. the first, second, third and the 

 fourth glume, respectively, of the sessile spikelet ; 6. anthers, ovary and Iodicules ; A-i, 

 A.-2, A-3 and A-4. the glumes of the pedicelled spikelet ; A-5. Iodicules of the pedicelled 

 spikelet. 



The sessile spikelets are bisexual about % inch or Jess, with a 

 long callus bearded on one side with long rusty hairs. There are 

 four glumes in the spikelet. The first glume is chartaceous, linear, 

 complicate, 2-toothed at the tip and with short bristles towards the 

 apex, 4-veined. The second glume is chartaceous, ovate-lanceolate, 

 much broader than the first, ciliate with long rufous bristles on the 

 keel, shortly toothed at the apex with an awn about Vz of an inch 

 and with broadly hyaline margins. The third glume is hyaline, 

 narrow-oblong, ciliate and obtuse. The fourth glume is narrow, 

 oblong, hyaline with an awn nearly an inch long. There are
