Plants hermaphroditic, caespitose, perennial. Culms erect or geniculate, hairy; internodes solid, terete. Leaves basal and
cauline; sheaths terete, or with compressed keels, margins open; auricles absent; ligules membranous (3-lobed); blades flat or
folded, not pungent (margins thickened and whitish). Panicles contracted (exserted); primary branches appressed,
terminating in a spikelet. Spikelets paired (lower staminate and short pedicellate and sterile, upper perfect and
longer pedicellate), terete, awned, pedicellate, pedicels without glands; florets 1, callus glabrous; reduced floret
absent; disarticulation above glumes; glumes (first 2-3-veined, and 2-awned, the second 1-2-veined and 1 awned),
unequal, shorter than floret, scabrous to hairy; lemmas 3-veined, membranous to chartaceous, entire, awned, veins
glabrous; paleas 2-veined, awnless, pubescent to hairy. Stamens 3; anthers yellow or reddish purple. Caryopses terete. Base
chromosome number x=10.
A genus of about 6 species native to the New World. Duval et al. (1994) reported that Lycurus is closely
aligned with Bealia, Blepharoneuron, Chaboissaea, Muhlenbergia, and Pereilema based on restriction site
variation in the chloroplast genome.
