Species: Sporobolus neglectus

Small Dropseed is an annual grass with tufted, wiry, ascending stems that are 10-40 cm tall. Its leaves have flat to inrolled blades that are 1-2 mm wide and sheaths that enfold the stem only at the base; the sheaths have long hairs along their margins and at the junction with the blade. There is a short membrane, or ligule, on the blade where it meets the sheath. Tiny, short-stalked, tightly erect spikelets are borne in a cylindrical inflorescence that is 1-3 cm long and enclosed in the leaf sheaths. Each egg-shaped spikelet has 1 flower that is ca. 2 mm long and consisting of two equal-length glumes enclosing a lemma and a palea of longer but ca. equal length.
