Characteristics

Annuals or perennials, with erect or geniculately ascending culms. Leaf-blades fairly broad, flat or folded, obtuse, occasionally apiculate; ligule a short membranous rim, ciliolate along the upper edge. Inflorescence terminal, consisting of 1-many digitate 1-sided spikes bearing flattened imbricate spikelets. Spikelets 2-flowered, ovate in side view, strongly laterally compressed, yellowish green, the lower floret hermaphrodite, the upper floret sterile or ♂; glumes ovate-lanceolate (when flattened), subequal, keeled, boat-shaped, membranous, the upper broader than the lower and occasionally with a short subterminal awn, usually 1-nerved (more in C. orientalis), acute; fertile lemma as long as the glumes or slightly longer, broadly ovate (when flattened), coriaceous, strongly keeled, ciliate along the nerves with a conspicuous subapical awn projecting from the spikelet, or shortly mucronulate; upper floret reduced, with lanceolate lemma and palea. Caryopsis ellipsoid or oblong, flattened on the back
More
Spikelets 2-flowered, strongly laterally compressed, sessile, in 1 row on a tough axis, disarticulating above the glumes; glumes subequal, membranous, keeled, enclosing the florets, acute to acuminate at the apex, the superior deciduous, sometimes with a short awn; fertile lemma coriaceous, keeled, mucronate or with a short subapical awn; distal floret well developed but male or sterile and smaller than the fertile.
Inflorescence of 1–many digitate 1-sided racemes bearing imbricate spikelets on a flat rhachis.
