"A rather slender, erect, leafy annual

 spikes 3 to 4 inches long. Culms teiete, 

 smooth, shining; nodes smooth, o*- the 

 southern part of San Diego county, Cal., 

 lower ones minutely puberulent; shea*hg 

 shorter than the internodes, the lower 

 smooth, striate; ligule membranous, 

 ones densely pubecent. the upper 

 rounded, entire, about 1 line long; leaf 

 blades rather rigid, 3 to 6 inches long, 2 

 to ?■ lines wide, stiiate, scabrous, gradual- 

 ly nar;owed to the pungently tipped apex. 

 Axis of the spike compressed, scabrous or 

 subciliate on the margins, the joints about 

 1 line long. Empty giumes setaceous, 

 rounded on the back, sulcate on the inuor 

 face below, scabrous, those of the central

 lateral spike'ets a little shorter; flowering 

 glume of the central spikelet i^/2 to 5 lines 

 long, scabrous; palea about as long as the 

 glume, scabrous on the keel above. Pro-
