 ceolate, subulate at tip, once and a half as long as floweret; awns of fer- 

 tile lower pale two or three times its length; lower pales of sterile spike- 

 lets 2-ranked ; awns of lower ones a little longer than pale, all lilac- 

 pui'ple orfiave&cent — Fields and roadsides; common.

 densely capitate, with short branches; fertile spikelets \-fiowered ; 

 glumes lanceolate, Ung-subulate, nearly twice as long as floweret ; awn 

 of fertile lower pale ^-10-times its length ; sterile pales not 2-ranked, but 

 somewhat spirally arranged ; lower awns 5-8 times as long as 'psAes, all

 several times bifurcated, rather long ; fertile spikelets otie- to two- 

 fioioered ; the others either all sterile, or hearing fertile flowerets at sum- 

 mit ; glumes lanceolate at base, gradually tapering into an awl-shaped 

 tip, longer than pale ;^ awn of fertile pale 3-4 times its length ; lower 

 awns 3-5 times as long as sterile pales, all straw-colored — Spring — Dry 

 places ; coast to middle mountain zones.

 stipitate, all perfect orthe uppermost tabescent. Glumes keeled, acutely, 

 1-3-nerved, as long as the flowerets or shorter. Lower pale keeled, 3-
