Stems erect and usually well-branched, 1-4 dm. high, short-hirsute with spreading or, es- 

 pecially on the upper parts, ascending hairs. Leaves narrowly linear to linear-lanceolate, hirsute- 

 hispid with rather short more or less ascending hairs, minutely pustulate; spikes m twos or 

 threes, usually crowded, 2-6 cm. long, bractless ; corolla 4-7 mm. broad ; fruiting calyx oblong- 

 ovoid, 3-5 mm. long; mature calyx-lobes lanceolate, connivent above, margins appressed silky- 

 pubescent, midrib sparsely hispid; nutlets 4, all similar, smooth and shining, rarely obscurely 

 tessellate, oblong-ovoid to lanceolate-ovoid, 2-2.5 mm. long, flattish dorsally, lateral angles 

 obtuse, groove closed above, forked below and often forming a small triangular areola; style 

 distinctly surpassing the nutlets. 



Sandy soils, Upper Sonoran Zone; eastern base of the Sierra Nevada near Bishop, Inyo County, Cali- 

 fornia, and Tehachapi Mountains south to the desert slopes of the Sierra Liebre and San Gabriel Mountains, 

 California. Type locality: "Mojave Desert." May-June.

Stems slender, solitary and usually strictly branched, 1-3 dm. high, spreading, short-hirsute. 

 Leaves narrowly linear to narrowly oblanceolate, ascending, hirsute, rarely pustulate; spikes 

 solitary or in pairs, 1-4 cm. long, rarely longer, bractless or rarely bracted below; corolla 

 about 1 mm. broad; fruiting calyx ovoid to oblong-ovoid, 2-3.5 mm. long, the lower becoming 

 distant; mature calyx-lobes lanceolate, the tips connivent, hirsute with ascending hairs, the 

 midrib also with a few spreading bristles; nutlets 4, all similar, lanceolate, 1.5-2 mm. long, 

 smooth and shiny or sometimes dull and minutely tessellate, nearly flat on the dorsal side, 

 distinctly angled on the margins, groove forked at base, closed or nearly so; style equaling 

 or a little shorter than the nutlets. 



Slopes and flats, in dry rocky or sandy soils, Arid Transition Zone; east of the Cascades from Okanogan 

 County, Washington, south through Oregon and Nevada to Inyo County, California, east to Montana and 

 Utah. Type locality: Wasatch Mountains, Utah. May-Sept.

Stems slender, simple with ascending branches above or frequently with several elongated 

 branches below, 1-2 dm. high, rather densely hirsute-hispid with rather short spreading hairs. 

 Leaves linear or narrowly oblanceolate, the lower 1.5-3 cm. long, the upper usiially much 

 reduced, pubescence similar to that on the stem but usually pustulate; spikelets solitary or in 

 pairs, 1-2 cm. long, usually dense, bractless; corolla 1 mm. or less in width; fruiting calyx 

 ovoid, divaricately spreading, 2-3 mm. long; mature calyx-lobes lanceolate, erect at apex, 

 rather densely tawny hirsute-villous, midrib with a few hirsute-hispid bristles not strongly 

 differentiated from the rest of the pubescence ; nutlets 1 or rarely 2-3 and unequally developed, 

 lanceolate, 1 . 5-2 mm. long, smooth and shiny, nearly flat on dorsal side, sides rounded at least 

 above, groove usually open to above the middle, scarcely forked below ; style about three-fourths 

 the height of the nutlet. 



Dry, usually brushy slopes. Upper Sonoran Zone; White Mountains, Inyo County and the higher ranges 

 of eastern Mojave Desert, California, east through Nevada and northern Arizona to Snake River, Idaho,
