Perennial herb from branched stem-bases with rhizomes; flowering stems 10-30 cm tall, mostly smooth below, long-hairy above.
All basal, kidney-shaped, 1.0-7.7 cm wide, 1/2 to 4/5 as long, coarsely 7- to 21-toothed, the teeth up to 1 cm long, the leaves smooth, sparsely or stiff-hairy near the base, sometimes fringed, the stalks long, 1- to 5-times blade length.
