Inflorescence composed of (2)5–14 racemes, 12–20 cm. long, erect to patent, 3–5 in a whorl, the superior ones often solitary along a short common axis, sometimes in a second whorl of 2–4 racemes. Rhachis triquetrous, broadly winged, up to 0.8 mm. wide, smooth with scabrous margins. Pedicels 2-nate, 0.5–3.0 mm. long, triangular, scabrous, scarcely broadened at the apex. Spikelets 2.8–3.7 mm. long, oblong-lanceolate. Inferior glume oblong triangular, sometimes slightly bifid.
