Herbs, annual, cespitose. Culms to 30 cm, bases soft. Leaves spreading to ascending, ¼–1/3 length of scapes; sheath borders tan, backs prominently ribbed, glabrous; blades filiform, 0.5 mm wide, involute, margins ciliate-scabrid, surface glabrous.

Spikelets redbrown, ovoid to lanceoloid, 3–5 mm; fertile scales ovate, 1.5–2 mm, apex acute, glabrous or distally puberulent, keel prominent, shortexcurrent. Flowers: stamens (1–) 2; anthers oblongelliptic, 0.5–0.7 mm. Achenes yellowish to pale-brown, trigonousobovoid, 1 mm, faces rugose. 2n = 84.

Discussion

A specimen of Bulbostylis capillaris collected by E. Hall (585) gives Oregon without a specific locality.

Bulbostylis capillaris is distributed over a broad range of physiographic types and occurs in many forms, the most distinctive of ours being var. crebra, which has, in addition to numerous longscaped anthelae, large numbers of spikelets at the plant base.
