Inflorescence of 5–10 racemes on an axis 3–7 cm. long; racemes 1–4 cm. long, secund, bearing single or paired spikelets (sometimes short side branchlets at base of longer racemes) on a ± pubescent triquetrous rhachis. Spikelets elliptic, 2–2.7 mm. long, glabrous or pubescent, sometimes with a short transverse fringe of hairs near the tip, acute to subacute, without a stipe; lower glume 1/3–1/2 the length of the spikelet, clasping; upper glume separated from the lower by a slight internode; upper lemma granulose to rugulose, acute to mucronulate.

B. villosa intergrades with B. comata, differing mainly in the simple secund racemes. Its distribution, Old World tropics omitting East Africa, is unusual but recalls that of Phragmites karka (Retz.) Steud.
