sheaths and leaves reddish. Leaf -sheaths 1 to 1^ in. long, or the 

 lowermost shorter, the ascending or suberect blades except the 

 shorter ones at the base of the culm, 1,^ to 3^. in. long from 

 scarcely 1 to 2 lines broad. Panicle half the height of the plant, 

 more or less oblong tapering at the base ; spikelets reaching I in., 

 but generally shorter, with 8 to 9 or fewer flowers ; barren glumes 

 about n line long, or the lower sometimes perceptibly shorter^ 

 1^ line; flowering glumes membranous with 3 strong nerves, the 

 lowest 1;V to 1} line long not including the awns. 



Near T. Elliotii Eendle, but distinguished by its larger laxer 

 panicle with smaller spikelets and glumes, and pilose habit.

Apparently perennial and caBspitose, culms ascending, ultimately 

 erect, geniculate, branching at the base ; nodes dark, glabrous , 

 cauline internodes 3 to 4, glabrous, terete, except the lowest 

 exceeding the shoit loose membranous .sheaths which are sparsely 

 pilose at the mouth only ; ligule a .short row of hairs ; blades 

 rigidulous, subpatent, linear-tapering, acute, flat or incurved, 

 glabrous except for a few hairs on the upper face at the base ; 

 inflorescence of a few spikelets sessile on the main rhachis, which 

 in one case bears a lateral branch ; spikelets ovate, densely many- 

 flowered, di.stichous, compressed ; glumes coriaceous, the lower 4 

 barren, 3- to 7-nerved, ovate-lanceolate to broadly ovate, increas- 

 ing in size and strength upwards, strongly cuspidate, keels scab- 

 ridulous, margin ciliate, especially near the base ; fertile glumes 

 broadly ovate, with a strong broad-margined ventricose base, and a 

 subtruncate strongly cuspidate apex, strongly T-nei-ved, 9 -nerved 

 below the apex, margins hyaline and ciliate especially near the 

 ba.se ; pale hyaline, large, flat, narrow-lanceolate, blunt, the 

 broad edges inflexed at the well-marked ciliate keels, a little 

 shorter than the glume ; anthers long, linear ; styles long, 

 plumose, projecting from between the cusps of the glumes. 



Plants small, culms reaching 1 ft, high and f, line in diameter ; 

 leaf-sheaths |^ to barely 1 in. long, blades scarcely exceeding 2 in. 

 long by 2 lines in width at the base, jointed to and ultimately 

 separating from the sheath. Inflorescence \\ in. long by scarcely 

 f in. broad ; spikelets about | in. long by i broad, the majority 

 contorted above the middle (probably from the attack of an insect).
