1. Ii. stipacea (Stipa-like), F. v. M. Fiagm. v. 206 ; Benth. Ft. Amtr. vii. 

 627. Stems 2 or 3ffc. high, the nodes bearded, otherwise glabrous. Leaves 

 narrow, flat. Panicle secund, rather dense, 4 to 5in. long, Spikelets narrow, 

 not numerons, nearly sessile along the branches. Outer glumes about 4 lines 

 long, glabrous, tapering to a fine point and produced into a straight awn, 

 sometimes nearly half as long as the glume. Flowering glumes shortly hairy all 

 over, with a slender curved awn about Ifin. long. Palea flat, tapering to a. 

 point divided into 2 awns nearly as long as the palea itself.

 narrow, convolute. Panicle dense, H to 2in. long, the rhaohis slightly hirsute. 

 Spikelets sessile on the short branches. Outer glumes 2 to 2J lines long, more 

 or less sprinkled with spreading hairs arising from tubercles, tapering into 

 awn-like points shorter than the glume. Flowering glumes shorter, densely 

 hairy all over, with a fine awn usually about lin. long. Palea tapering into 2 

 fine awn-like points a little shorter than the glume itself.

 Stems erect, 2ft. high or more, the nodes densely bearded with long silky hairs. 

 Panicle dense, 2 to 4in. long. Spikelets sessile and crowded along the short 

 erect or slightly spreading branches. Outer glumes nearly 4 lines long, tapering 

 to a fine point, hispid with long rigid spreading hairs. Flowering glumes nearly 

 as long, narrow, hairy outside, tapering into an awn of about lin. Palea 

 tapering into a short entire point. — Aira squarrosa, Spreng. Syst. i. 272.
