Dichanthelium acuminatum subsp. acuminatum
Plants grayish olive green, densely velvety-villous throughout. Cauline nodes densely villous, with a glabrous ring below; fall phase branching extensively from the midculm nodes, forming conspicuous flabellate fascicles of branches. Cauline sheaths densely soft spreading-villous, often with inconspicuous smaller hairs underneath; midculm sheaths about 1/2 as long as the internodes; blades 6-12 cm long, to 10 mm wide, ascending to often spreading and slightly incurved, softly pubescent on both surfaces, with papillose-based cilia for most of their length. Primary panicles usually well-exserted, on peduncles longer than 8 cm. Spikelets 1.6-1.9 mm, broadly ellipsoid or obovoid.
