Description
Generally, for the Dichanthelium genus, they have "spikelets usually in panicles, round or nearly so in cross section, 2-flowered, terminal fertile, basal sterile, neutral or staminate. First glume usually present, 2nd glume and sterile lemma similar; fertile lemma and palea indurate without hyaline margins. Taxonomically our most difficult and least understood genus of grasses, more than 100 species an varieties are ascribed to the Carolinas by some authors. Note general descriptions for species groups (e.g., 1-4, 5-8, 9-13, and 26-62)." - Radford et al 1964.
Specifically, for the D. leucothrix species, they are "perennial with distinct basal rosettes; branching, when present, from nodes above basal rosette. Leaves basal and cauline, vernal and autumnal. Culms 3-6.5 dm tall, nodes slightly bearded, internodes glabrous or pilose. Blades to 6 cm long, 2-5 cm wide, glabrous above, setose basally, puberulent beneath, margins scaberulous, basally ciliate; sheaths sparsely pilose or glabrous, margins occasionally ciliate; ligules ciliate, 2-3 mm long. Panicle 3-6 cm long, 2.5-4 cm broad; rachis appressed pilose or glabrous, branches spreading, smoothish. Spikelets ellipsoid, 1.2-1.4 mm long; pedicels smoothish. First glume glabrous or pubescent, truncate or acute, 0.2-0.5 mm long, 2nd glume and sterile lemma pubescent, obtuse, 1.2-1.4 mm long; fertile lemma and palea 1.1-1.5 mm long. Grain not seen." - Radford et al 1964.
