Leaves are 3-13 cm long, 1.5-4 cm wide, ovare-oblong or lanceolate, narrowed at the top, sagittate at the base, naked, rarely villously pubescent. Lobes at the base of leaves are sharp, narrow, rejected outside. The plates of the leaves have a fine wavy margin on the edge. Radical and bottom stem leaves have long ridge pubescent stalks. The top leaves have short stalks, or sedentary, narrower and finer then radical ones. The inflorescence is a dense pyramidal panicle. Bracteoles are filmy, 1-3-dentate. Internal shares of perianth at fruits are wide-ovare, slightly jagged on its edges (slightly learned by rote) and narrow at the top, mesh, with a deep heart-shaped base, 3-4 mm long. Fruits are nutlets, trihedral, dark and brilliant. Blossoms in June-July, fructifies in July-August.
