Stem 8-16 in., erect or with the branches geniculately ascending, smooth ; 

 lowest internodes short, laxly or closely clothed with short sheaths, the following 

 2-4 elongMte, uppermost exserted. Leaves 2-5 by -^ in., glabrous, smooth or 

 nearly so, flaccid or rather firm ; lower sheaths scarious, uppermost about 4 in. ; 

 ligule y^ 5 iu-, ovate. Panicle 2-4 in., erect or inclined ; lower branches capillary, 

 floxuous, often spreading or deflexed, naked except towards the tips smooth. Spike- 

 lets shortly or the terminal longer pedicelled, green, generally suffused with purple; 

 gl. I 5-i in., sub-obtuse or -acute, margins broadly hyaline, keel smooth or roughish ; 

 JI rather longer, ovate-oblong, sub-obtuse, 3-nerved, lateral nerves often short; flg. 

 gls. i-i in., nearly glabrous or keel and nerves at the base silky, smooth or minutely 

 rough ; palea rather shorter than the gl., dorsally most minutely puberulous between 

 the keels. Anthers yV~i ^ n - h'near. 



6\ Glumes I &f II thin, acute or acuminate, I \-nerved, or with a very 

 slender 2nd, rarely 3-nerved ; anthers very minute, rarely j~ in. long. 

 Usually perennial, sometimes flg. in the first year, or truly annual ; leaves 

 & often stem flaccid ; stems loosely tufted or on a slender rhizome & with more 

 or less elongate lower internodes, hardly stoloniferous when flowering.

Stems Ipoeely tufted, 12 ft., suberect from a rooting base, intemodes 5-6, upper 

 gradually longer, loosely or rather tightly sheathed, or the upper shortly exserted. 

 Leaves up to 4-6 by T V~To * n '> fl acc 'd, S at j smooth or margins roughish ; sheaths 

 smooth, uppermost up to 5 in., usually longer than the blade ; ligule erose. Panicle 

 4-6 in. long, lax, sometimes subsecund ; lower branches subrigid or flexuous, slender, 

 at length spreading or deflexed, unbranched except the tips or loosely branched 

 almost from the base. Spikelets ovate-oblong, pale green ; gls. firm ; I in.,

 being taller, with leaves long-attenuate, ligule very short, branches of panicle 3-5- 

 nate, in the wool, and in the keels of the palea not ciliate ; and from P. annua var. 

 nepalensis, in the 3-5-nate more flexuous branches, rather larger spikelets, narrower 

 firmer gls. with more prominent nerves, rough keels of the palea and rather longer 

 anthers.
