 mose ; awn bent and twisted, exceeding the glumes. — Arctic Coast, the Sas-

 Humboldt Mountains ; 10,000 feet altitude ; August. (1,291.) 



Eeiocoma^ cuspidata, Nutt. Perennial; culms 1-2° high, simple, 

 rather rigid and somewhat scabrous; sheaths scabrous, equaling the inter- 

 nodes, the upper ones often dilated; leaves narrow, convolute, elongated, 

 (2-18';) panicle frequently included at base, dichotomously branched, the 

 spikelets solitary upon capillary peduncles ; glumes 2^-4" long, usually more 

 or less purple, pubescent ; outer palet deep brown, 1^" long, the nearly 

 straight triquetrous awn 1^-2" long. — From New Mexico to Northern Dakota

' EEIOCOMA, Nutt. Spikelets 1-flowered, in a loose open panicle. Glumes thin, nearly equal, 

 strongly 3-nerved, subventricose at base, attenuate-rostrate above, somewhat exceeding the persistent 

 flower. Callus short, thick. Palets rigid, coriaceous, the outer oval, densely covered throughout with 

 long white silky hairs, and terminated with a short stout deciduous awn, the upper included, narrower, 

 scarcely shorter. Stamens 2-3 ; anthers ohlong-linear, bearded at the apex. Scales conspicuous, nearly 

 equaling the oblong seed. — Steudel in his description of Fendler's specimen, (under Fmdleiia,) describes a 

 neuter floret as a single very thin palet, much narrower and shorter- than the glumes. This is usually 

 only indicated by a very short and thick process at the base of the upper palet.
