Leaves nearly all basal; petiole 3-12 cm; leaf blade reniform or orbicular-reniform, 1.5-3 × 2-4 cm, papery, abaxially sparsely hirtellous along veins, adaxially glabrous, base broadly cordate, margin subentire, apex obtuse; cauline ones usually rudimentary; ocrea shortly tubular, membranous, apex oblique. Inflorescence terminal, paniculate; bracts membranous, each 2-5-flowered. Pedicels slender, articulate below middle. Flowers bisexual. Perianth greenish or pinkish; outer tepals smaller, deflexed; inner ones accrescent in fruit, obovate, appressed. Filaments dilated at base. Achenes ovoid, broadly winged at margin, 4-6 mm in diam.; wings pink, membranous, denticulate. Fl. Jun-Oct, fr. Jul-Nov. 2n = 14, 42.
