glabrous, glaucous perennial, 7-10% high, with linear, plane, or 
mostly involute leaves, and exserted rather densely flowered 
panicles 1.5-24" long. Culms glabrous throughout; sheaths 
glabrous, shorter than the internodes; ligule firm, truncate, 1-2™ 
long ; leaf blades rather firm, usually involute, at least when dry, 
scabrous only on the margins, those of the culm 1—2% long, 
3-4™ wide, those of the innovations often 3% in length. 
Panicle lanceolate, 1.5-3°™ in diameter, pale or purplish, rachis 
nearly glabrous, branches erect or ascending, fasciculate, rather 
densely flowered, scabrous, the lower ones 5-7 long. Spikelets 
lanceolate, 6-10™™ long, 4-6-flowered; empty glumes lanceolate, 
acuminate, 3-nerved, scabrous on the keels, the first 3.5-47™ 
long, the second somewhat longer; flowering glumes lanceolate, 
acute, about 5™™" long, faintly 5-nerved, minutely punctate 
scabrous throughout, basal hairs entirely wanting. Palea about 
equaling the glumes, ciliate scabrous on the keels. 
Type specimen collected at Steptoe, Washington, G. #. Vasey, number 
3026, June 25, 1900. Numbers 3034 and 3028, G. X. Vasey, June 1, from the 
same locality, are referred here, as well as number 2421A, W. C. Cusick, 
ibis county, Oregon, June, 1900. Number 3028 Vasey cited above is a 
glaucous form with plane leaves, but otherwise like the type. It is 
ae related to Poa nevadensis, but is distinguished by its more robust 
abit, and glabrous leaves and culms. In Poa mevadensis the culms are 
decidedly scabrous below the panicles and the leaves are very scabrous. 
From Poa ampia this species is distinguished by its more strict panicles, more 
numerously flowered spikelets, and absence of a rootstock. 
Puccinellia rubida, n. sp—A densely tufted ‘biennial, from 
numerous fibrous roots. Culms few, erect or geniculate below, 
slender, 2-3*™ long, smooth, naked from the middle, usually of 
a dark red color. Leaves very numerous from the base, 3-7 = 
long, mostly falcate, strongly involute, smooth and glaucous on 
the outside, scabrous along the edges, rigid and pungently 
pointed, cauline ones 2 or 3, very short; sheaths longer than the 
internodes, smooth, glaucous green to purplish; ligule 1™™ long, 
received a copy of Mr. T. A. Williams’ diagnosis of this species. Professor Spillman 
kindly suggested that I include it for publication in this article, with an explanation 
that it has been in manuscript for some two years and would have been published 
sooner had it not been for Mr. Williams’ death.
