Stems densely villous-hirsute (hairs retrorse). Leaves: basal blades ovate, 1.5-6 cm wide, lengths to 2 times widths, bases rounded to attenuate, margins mostly coarsely crenate, faces hairy; cauline sessile distally, elliptic to lanceolate (distalmost ovate), not notably smaller distally, bases ± auriculate (clasping), margins sharply serrate (teeth remote), faces densely villous-hirsute. Phyllaries reflexed, 1-2 × 0.2-0.6 cm, densely hairy. Receptacles 11-17 mm diam.; palea margins ciliate, faces mostly glabrous. Ray florets 12-20; laminae 15-25 mm.

Flowering late summer-fall. Stream banks, woodland ridges; 100-300 m; Ill., Ind., Ohio.

A single colony of this species was found in 1914 and in the same place in 1916 on the moist slopes of the north bank of Wildcat Creek in section 1 in Carroll County, about 150 feet east of where the creek is crossed by the Delphi and Frankfort pike, about 9 miles southeast of Delphi. The type locality was visited in later years and the species had disappeared. I have searched up and down the creek from this place and I have never been able to find additional specimens. In September, 1932, I found a large colony of it in a roadside ditch about a mile and a half southwest of Williamsport in Warren County.
