Leaves long petiolate; leaf blade ovate to suborbicular, angled, weakly lobed, or deeply palmatipartite, margin crenate or dentate, apex acute to obtuse. Flowers axillary, solitary or fascicled, often arranged into terminal racemes. Epicalyx lobes 6 or 7, basally connate. Calyx 5-lobed, ± pubescent. Petals pink, white, purple, or yellow, usually more than 3 cm wide, apex notched. Staminal column glabrous with anthers clustered at apex; anthers yellow and compact. Ovary 15- or more loculed; ovules 1 per locule, erect; styles as many as locules; stigmas decurrent, filiform. Fruit a schizocarp, disk-shaped, fruit axis as long as or shorter than carpels; mericarps more than 15, laterally compressed and circular with a prominent ventral notch, glabrous or pubescent, 2-celled, proximal cell 1-seeded, distal cell sterile. Seed glabrous or pustulose.
