Annual. Culms robust. Leaf blades linear, flat; ligule membranous. Inflorescence of single axillary racemes; racemes cylindrical, fragile, transversely articulated; rachis internodes stout, flattened or semi-cylindrical, deeply cupped at apex, truncate at base with a prominent central peg broadened into a flared elaiosome. Sessile spikelet sunk within rachis; lower glume ovate-oblong, leathery, shallowly convex, marginally 2-keeled, apex obtuse or acute, narrowly winged; upper glume boat-shaped; lower floret staminate, palea present; upper floret with entire awnless lemma. Pedicelled spikelet tightly erect, as long as or shorter than sessile spikelet, herbaceous; pedicel broad, of similar texture to, and partly or wholly adnate to adjacent rachis internode.
Erect annuals. Leaf-blades flat; ligule a very short membrane. Inflorescence a single raceme, either terminal or aggregated into a spathate false panicle; racemes cylindrical; internodes squatly clavate, fused to the adjacent pedicel. Sessile spikelet sunk in the internode; callus truncate, with prominent central peg; lower glume coriaceous, broadly convex, 2-keeled, smooth, narrowly winged at the apex; lower floret ♂, with hyaline lemma and well-developed palea; upper lemma entire and awnless. Caryopsis ovate in face view, crescentic in side view. Pedicelled spikelet herbaceous or scarious, a little smaller than the sessile; pedicel oblong, flattened, scarcely distinguishable from the internode.
Sessile spikelet callus truncate, with prominent central peg or ridge; inferior glume coriaceous, broadly convex on the back, 2-keeled, smooth, narrowly winged at the apex; inferior floret male, with a hyaline lemma and well developed palea; superior lemma entire and awnless.
