Agrostis hooveri
Plants perennial; cespitose, not rhizomatous, not stoloniferous. Culms 30-80 cm, erect, usually with more than 3 nodes. Leaves mostly on the lower 1/2 of the culm; basal leaves withered by anthesis; lower leaf-sheaths finely tomentose, the tomentum extending to below-ground; upper leaf-sheaths smooth; ligules 2.5-6 mm, dorsal surfaces scabridulous, apices acute to truncate, lacerate; blades 10-16 cm long, 0.5-1 (2) mm wide, flat, becoming involute. Panicles (4) 10-17 cm long, 2-5 cm wide, broadly lanceolate, usually open, exserted from the upper sheaths at maturity, lowest node with 1-8 branches; branches scabrous, generally ascending, mostly branching at about midlength, sometimes to near the base, lower branches 1.5-5 cm; pedicels 0.4-5 mm. Spikelets lanceolate, slightly purplish. Glumes equal to subequal, 1.8-3 mm, 1-veined, scabridulous on the veins, sometimes also on the body, acute; callus hairs to 0.3 mm, abundant; lemmas 1.5-2 mm, scabridulous to warty throughout or only on the veins, translucent to opaque, 5-veined, veins prominent distally, apices truncate, minutely toothed to about 0.2 mm, awned on the lower 1/3, awns to 2.5 mm, geniculate, persistent; paleas absent or minute; anthers 3, 1-1.5 mm, usually shed at anthesis. Caryopses 1-1.5 mm; endosperm liquid. 2n = unknown.
