Leaves all basal and spirally arranged, or sometimes 1 or 2 cauline at nodes, with a well-developed blade; blade flat to channelled above, scaberulous or glabrous on the margins; ligule absent.
Inflorescence compound, paniculiform or subracemose, with several internodes with 2–10 distant fascicles of branches; branches 1–4 at each node. Spikelets subsessile or pedicellate, in clusters of 2–24, usually 1-flowered, the rachis not elongated or flexuous. Glumes (floral bracts) 4–7, obscurely distichous; basal 2 or more glumes sterile; upper glume with a bisexual flower. Hypogynous bristles (3–)6, linear to lanceolate, margins with dense to scattered ciliate or ciliate-plumose hairs. Stamens 3; filaments glabrous. Style 3-fid, uniform or slightly swollen at the base.
Nutlet narrow-ellipsoid to obovoid, with 3 whitish ribs, slightly reticulate-rugulose at 40X magnification, papillate or shortly hispidulous at the apex, otherwise glabrous.
