Leaves radical, usually 3 or 4, peltate, glabrous or sparsely villous when young, petiole 10-450 mm long with stipules adnate and sheathing for 20-40 mm, hollow, blade orbicular, leathery, laterally folded when young, (5-)30-150(-300) mm diam., crenulate-dentate with apical tooth largest, dull dark green adaxially with irregular pale markings along veins, margins reddish and cartilaginous with callus at apex of each serration. Flowers (1)2-18 in a pedunculate cyme, (18-)20-30 mm diam.; peduncle 2-3 x as long as leaves, (30-)100-600 mm long, 1.5-10.0 mm diam. at base, hollow, usually with apical fringe of short, obtuse hairs at base of sepals; bracts ovate-suborbicular, cucullate, finely or irregularly toothed with reddish, cartilaginous margins, rarely lowermost leaflike and amplexicaul. Sepals (4)5, reflexed, caducous, ovate to suborbicular, cucullate, 4-6 mm long, glabrous or obtusely hispidulous beneath towards base, margins irregularly toothed, yellowish or with reddish margins. Petals (11)12-15(-17), narrowly obovate-cuneate, 8-15 x 2.5-4.0 mm, varnished bright yellow adaxially but dull and paler beneath, narrowed into short fleshy claw in basal ± 1 mm, truncate to acute, veins branched, nectary lunate. Stamens ± 50 in ± 6 series, filaments ± 5 mm long, anthers ± 0.5 mm long. Carpels ±50-100, glabrous.
