and axils naked, the branclilets and long capillary pedicels very scabrous ; 
spikelets less than 1" long, frequently 2-flowered, the glumes slightly une- 
qual, hispid upon the back, acute, a third shorter than the nearly equal palets ; 
lower palet submucronate, the upper obtuse. — The specimens accord very 
well with the description of the Chilian plant, and also much resemble forms 
of Eragrostris capillaris. Mono Lake, California, (6095 Bolander ;) Colorado, 
(641 Hall & Harbour, 630 Vasey ;) also 571 and blV Torrey,.from AVestern 
Nevada. On alkaline soils in Carson, Unionville and Ruby Valleys, Nevada ; 
4-6,000 feet altitude ; August-October. (1,277.) 
ViLFA EAMULOSA, HBK. Steud. Gram. 158. {Sjyoroholus, Kth.) Root 
annual, fibrous; culms very slender, branching from the base, 3-10' high; 
sheaths usually exceeding the internodes and glabrous or sHghtly hairy ; leaves 
flat or convolute, 1-2' long, J-1" wide, recurved, roughish ; panicle elon_ 
gated, often sheathed at base, very loose and spreading, with scattered branch- 
lets ; spikelets scarcely J" long, obtusish, on capillary pedicels ; glumes nearly 
equal, minutely hairy upon the margin or naked ; palets obtuse, nearly twice 
longer.— Mono Lake, California, (6096 Bolander;) Colorado, (643 Hall & 
Harbour.) Banks of the Truckee River; Nevada; 4,000 feet altitude;

YiLFA DEPAUPERATA, Torr. Hook. Fl. Bor.-Amer. 2. 257, t. 236. Root 
perennial, creeping ; culms ascending, appressed-branched, slender, often ge- 
niculate, glabrous, striate, rather rigid, J-2° long; leaves 1-3' long, narrow 
and usually convolute, spreading or recurved ; panicle very slender and con- 
tracted, 1-3' long, compound or often nearly simple ; spikelets small ; glumes 
unequal, ovate, obtuse or acutish, membranous, two-thirds the length of the 
acute lower palet, which is more or less obscurely 3-nerved. — Resembling 
F. cusinduta and scarcely differing except in the shorter obtuse glumes of the 
rather smaller flowers. Lower palet a little more than 1" long, glabrous or 
shghtly scabrous on the midnerve, the upper one obtuse or erose at the sum- 
mit, not seen bifid as described and figured by Hooker. From AVesteru 
Texas and New Mexico to Colorado and the Saskatchewan ; California. 
Ruby and Huntington Valleys, Nevada, abundant and forming a dense turf • 
also in Washoe and Carson Valleys, (563 and 566 Torrey ;) 4-6,000 feet alti- 
tude ; July, August. (1,279.)
