Description of the genus

Annuals or perennials. Leaves flat or folded, sometimes plicate. Ligule usually a ciliate rim. Inflorescence usually a panicle, either open or dense and spike-like; the spikelets subtended by 1 or more bristles which persist on the axis after the spikelets fall. Spikelets oblong to ovate, ± plano-convex, awnless; glumes unequal, the lower generally much smaller, ovate from a clasping base; lower floret male or barren, as long as the spikelet, herbaceous; upper lemma crustaceous, strongly convex on the back, often rugose.

Derivation of name: from the Latin, seta, a bristle, referring to the persistent bristles subtending the spikelets
