Loosely tufted annual; culms 15–70 cm. high, often weak and ascending. Leaf-blades broadly linear, 4–25 cm. long, 4–22 mm. wide. Inflorescence of 7–15 racemes, borne on an axis 6–15 cm. long; racemes 2–10 cm. long, often compound, bearing mostly paired distant spikelets spreading from the triquetrous rhachis, the inflorescence imitating a panicle; pedicels or some of them, longer than the spikelets, up to 15 mm. long. Spikelets broadly elliptic, 2.5–3.5 mm. long, glabrous to pubescent, acute, with a short stipe up to 0.5 mm. long; lower glume 1/3–1/2 the length of the spikelet; upper glume and lower lemma membranous; upper lemma rugose, subacute to acute.

B. deflexa intergrades completely with B. ramosa, and may be no more than a geographical race of the latter. This relationship discourages the transfer of B. deflexa to Panicum despite its panicle-like inflorescence.
