Culms few–several, spreading, 1.5–5 dm, glabrous except the appressed-hairy nodes; sheaths glabrous (and sometimes viscous-spotted) on the back, villous-ciliate with hairs usually 1–2 mm, some of the sheaths shorter than the internodes; ligule typically none, but sometimes a band of hairs to 1 mm; blades cordate and papillose-ciliate at base, the largest ones 6–12 cm × 7–15 mm, the primary veins scarcely stronger than the sets of 3–5 intermediate veins; flag-lf mostly 3–9 cm, typically borne ± midway between the stem-base and the panicle-tip; primary panicle 5–10 × 4–8 cm, long-exsert at anthesis, with spreading branches; spikelets (excluding the first glume) almost spherical, minutely puberulent, 1.3–1.9 mm, the first glume a third as long, broadly ovate; autumnal phase more widely spreading or prostrate, the few branches mostly from the base and lower nodes, the lvs and panicles scarcely reduced; 2n=18. Moist or dry, preferable shady places; Mass. and Vt. to O. and Kans., s. to Fla. and Tex. (Dichanthelium s.)
Perennial; culms 20-55 cm. high, in small tufts, erect or spreading, the nodes appressed-pubescent; sheaths usually longer than the internodes, the margins ciliate, otherwise glabrous, often viscid between the nerves, especially toward the summit; ligule very short or obsolete; blades 4-10 cm. long, 5-15 mm. wide, cordate, the white cartilaginous margins papillose-ciliate toward the base; panicles 5-10 cm. long, long-exserted, loosely flowered, the axis, branches and pedicels viscid; spike-lets subspherical, 1.6-1.8 mm. long, pubescent, or sometimes nearly glabrous; fruit 1.4-1.5 mm. long. Autumnal phase sparingly branched, spreading, the blades and panicles not much reduced.
