[Erioneuron pulchellum (Kunth) Tateoka, more]
Culms (1)4-15 cm, scabrous or puberulent; peduncles (internode
below the panicles) 3-7(11) cm. Sheaths striate, margins scarious; ligules
3-5 mm; blades (1)2-6 cm, abaxial surfaces scabrous, adaxial surfaces
scabridulous. Panicles 1-2.5 cm long, 1-1.5 cm wide, densely
white-pubescent, light green or purple-tinged. Spikelets (5)6-9(10)

Lower glumes 6-8.5 mm; upper glumes 6.5-9 mm, as long as
or longer than the florets; lemmas 3-5.5 mm, lobes (1)3-3.2 mm,
midveins extending into straight (1.5)2.5-4 mm awns; paleas 2-3.5
mm, keels long pilose proximally, ciliate distally; anthers 0.2-0.5
mm. Caryopses 1-1.5
mm, translucent. 2n = 16.
Dasyochloa pulchella grows in rocky soils of arid regions.Its range extends
from the western United States southward to central Mexico. It is the most common
grass in the Larrea-Flourensia scrub of the southwestern United
States and adjacent Mexico.
Plant: Low perennial grass, appearing annual, < 15 cm; culms numerous, wiry, consisting mainly of a single elongated internode bearing at its apex a fascicle of leaves and spikelets, the fascicles eventually bending over to the ground and rooting; blades 1-5 cm long; inflorescence of capitate clusters of sessile or short-pedicelled spikelets most 7-13 mm long, 6 to 12-flowered.
