Plants annual or perennial. Culms 10-70 cm. Sheaths open, glabrous, usually longer than the internodes; ligules membranous or hyaline, truncate to obtuse, often decurrent; blades flat to involute, abaxial surfaces glabrous, sometimes scabrous, adaxial surfaces shortly pubescent. Inflorescences terminal, panicles, exceeding the leaves; branches spreading to ascending; pedicels capillary, lax, minutely glandular just below the spikelets. Spikelets with 1 floret, slightly laterally compressed, grayish-green; disarticulation above the glumes. Glumes subequal, ovate to obtuse, faintly 1-veined, glabrous; lemmas slightly longer and firmer than the glumes, 3-veined, veins and margins densely sericeous, hairs 0.1-0.7 (1) mm, apices acute to obtuse, occasionally mucronate; paleas 2-veined, densely villous between the veins; anthers 3, purplish, x = 8.

Distribution

Utah, Ariz., Colo., N.Mex., Tex.

Discussion

Blepharoneuron is a genus of two species: a slender annual, B. shepherdii (Vasey) P.M. Peterson & Annable, which is known only from northern Mexico, and B. tricholepis, which is native to the Flora region.

"decumbent" is not a number.
