Shrubs or treelets 1–8 m. tall, stems densely pubescent when young and minutely pubescent at maturity, the trichomes stellate or simple, rarely dendroid. Leaves simple, to 22 cm long and 19 cm wide, generally decreasing in size towards the stem apex. Stipules often early deciduous, linear, narrowly oblong or ovate, 0.3–1.5 cm long, 0.1–0.6 cm wide.Petioles 2–20 cm long, with the longer petioles on older partsof the plant. Lamina elliptic to broadly ovate (broadlyobovate in species with lobed leaves), unlobed, shallowly3-lobed or 5–7-lobed, basally cordate to lobate, rounded,cuneate, near-truncate or oblique, margins serrate-crenate toserrulate-crenulate or subentire (rarely dentate or entire), apexacute to acuminate, leaf surface stellate-pubescent, often moredensely on abaxial surface; leaves sometimes discolorous,venation brochidodromous. Flowers solitary, paired or in clus-ters of 3 flowers, axillary, on pedicels to 10 cm long. Involucelabsent. Calyces gamosepalous, 5-lobed, the lobes 1–4.5 cm,often heavily veined or keeled, the midvein prominent,minutely to densely stellate pubescent (sometimes den-droid, rarely simple), the indumentum often brown, tan orferrugineous (rarely silvery-tan or white), the lobes ovate-lanceolate, free from the tube 2/8–7/8 of the way to the acuteapex. Corolla rotate or campanulate, exceeding calyx in length, the petals obovate and often clawed at the base, 1.5–5.5 cm long, 0.5–5 cm wide; red, white, cream, yellow, purple,lavender, pink, or burgundy, usually prominently veined, the veins sometimes of another color. Staminal column usually exserted but sometimes included, 0.7–5 cm long, glabrous.Carpels 8–14(–16), 4–13-ovulate. Styles equal in number to carpels, surpassing the anther mass by up to 1 cm orincluded. Stigmas capitate. Fruits schizocarpic, to 5 cm indiameter. Mericarps unilocular, sclerotic and brown to black at maturity, 1–4.8 cm long, sparsely to densely stellate-pubescent on outer wall, minutely stellate-pubecent on innerwall, dehiscing dorsally, the dorsal margin entire, subentire,apically cuspidate, or with a lacerate, wing-like projection.Seeds to 4 mm long, stellate pubescent or pilose. Base chromo-some number: x = 8.
