120 Bulletin VII. 1. 



Spikelets six to eight lines long-, six- to ten-flowered, ovate or 

 oblong-lanceolate, somewhat flattened, downy, erect; empty 

 glumes lanceolate, acute, the first three-, the second five- to seven- 

 nerved; flowering glumes oblong, lanceolate, prominently seven- 

 nerved, with slender straight awns as long as the glumes. 

 Open waste places, not common. 



5. Bromus racemosus Linn. 



Plate XLIII. Figure 172. 



An annual one to three feet high, with a nearly erect, spar- 

 ingly-branched panicle. Branches of the panicle slightly spread- 

 ing and somewhat nodding at the tips. Spikelets ovate-oblong, six 

 to nine lines long, five- to ten- flowered; flowering glumes round on 

 the back, somewhat ventricose, shining, awned. Awns straight, 

 about as long as the glumes. 



This species is quite distinct from Bromus mollis ; the panicle is 

 more open and often nodding, the spikelets are a little larger and 

 more turgid, the nerves of the glumes less prominent, and the 

 leaves and sheaths are never soft-downy. 



A very common grass in cultivated fields and waste places, 

 often mistaken for Chess. 



6. Bromus sterilis Linn. 



Plate XLIV. Figure 178. 



An annual, with erect, rather slender, leafy stems, twelve to 

 twenty-four inches high, smooth. Sheaths striate, more or less 

 pubescent, at least the lower ones, with deflexed hairs; ligule short, 

 obtuse; leaf -blade linear, soft and downy on both sides, with a few 

 longer hairs on the margins near the base. Panicle six to ten 

 inches long, nodding, with widely spreading, nearly simple 

 branches. Spikelets pendulous, lanceolate, six- to ten-flowered; 

 empty glumes narrow-lanceolate, long acuminate-pointed; flower- 

 ing glumes lanceolate, scabrous, somewhat compressed, seven- 

 nerved; awn about an inch long, exceeding the glume; palea 

 notched at its apex, the nerves strongly fringed. 



In dry fields and waste grounds, introduced. Not common. 

 Worthless. 



7. Bromus unioloides H. B. K. {Ceratochloa australis Spr.) Rescue- 



grass. 



Plate XLIV, Figure 174. 



An erect, usually annual grass, one to three feet high, with more 

 or less pubescent, flat leaves, and usually nodding loose panicles of 

 rather large, strongly flattened spikelets. Sheaths and leaves 

 scabrous; ligule rather long, obtuse. Panicle in vigorous plants 

 large, with widely spreading branches. Spikelets oblong-lanceo- 

 late, eight to sixteen lines long, six- to ten-flowered; flowering 

 glumes about six lines long; glumes all strongly compressed from 

 the sides and keeled. 



This grass has been introduced into some sections of the State,
