Fibrous-rooted perennial from a short rhizome, essentially glabrous by flowering time, 3-7 dm. tall.

Leaves thin, the basal ones long-petiolate, the blades sharply toothed, ovate, cordate to truncate at the base, the cauline ones few, progressively reduced upward, becoming sessile, pinnatifid or incised toward their bases.

The sub-cordate basal leaves that are sharply toothed but not otherwise divided is characteristic of this species.
