DESCRIPTION. 



Stems erect, rarely geniculate at base, 10 to 30, rarely 40 cm. higli, glabrous, 

 3-jointed; flheaths pmootb, longer than the iaternodes; li^ule very short; blades 

 linear^ glabrous, flat or loosely invtdute; panicle usually dense, narrow, 5 to 10 cm, 

 long, seldom longer; rays solitary, rather short, apprcssed; spikelets pale green, 4 or 

 5-flowered, to 12 nmi. long, on stalks 2 to 5 mm. long; glumes unequal, the lower 

 1-nervcd, 4 to 4.5 mm. long, the u]>pcr 3-nerved, Oto 7 mm. long; lemma lanceolate, 

 scabrous above, 7 to 8 mm. long, attenuate into an awn 10 to 13 mm. long; palea

 labeled it myuros or microstachyn. From the former it is easily distinguished by its 

 different glumes. Normal forms of F. padjica are easily distinguislie<l by the divar- 

 icately branching: panicle, but shade or diminutive forms sinmlate Aro?7?on/fs closely. 

 The best distinction in such cases is furnished by the palea. In pacifica the iiiflexed
