Anthaenantia villosa

ANTHAENANTIA Beauv. Silkyscale
Plants caespitose or rhizomatous, perennial. Culms erect (stiff), glabrous; internodes solid, terete. Leaves not differentiated into two kinds (basal rosette absent), basal and cauline, not distinctly distichous; sheaths terete; ligules a ciliate membrane; blades flat. Panicles narrow or loosely contracted; primary branches ascending (secondary branches spreading), terminating in a spikelet; bristles absent below spikelets. Spikelets solitary; not embedded in branch, laterally compressed or dorsiventrally compressed; disarticulation below spikelets; florets 2; lower sterile and staminate or without stamen (villous); upper fertile, more than eight tenths lower floret length; first glumes absent, not fused with callus; second glumes present (villous); 0.9-1 times spikelet length, not saccate, 5-veined; lemmas of upper florets indurate or cartilaginous, smooth, dark brown, glabrous, margin involute, not differentiated at apex, awnless; palea of upper florets present. Stamens 3; anthers light brown. Base chromosome number x=10.

A North American genus of two species. Anthaenantia has a spikelet morphology that is similar to Digitaria. One species is common in pine barrens of the southeastern United States and the other in wet or boggy habitats of the same area. These species are occasional in East Texas.
