Herbs, perennial, to 2.5 m. Stems glabrous or variously hairy, but without line of curved hairs. Leaves: stipules subulate, 1–4 mm; petiole 1/4–3/4 blade, glabrate or finely hairy; blade narrowly to broadly lanceolate to triangular-ovate or orbiculate, 3-lobed or unlobed, 8–20 × 3–13 cm, base cordate to cuneate, margins crenate to dentate or serrate, apex acute to acuminate, surfaces variously hairy, sometimes glabrous adaxially, nectary absent. Inflorescences solitary flowers in axils of distal leaves, pedicels of later-produced flowers often adnate to subtending petioles. Pedicels variously jointed sub-basally to distally, 2–15 cm, 1/2–1 1/2 as long as petiole, glabrate or finely hairy; involucellar bractlets [8–] 10–14 [or 15], linearlanceolate, 0.5–4.5 (–5) cm, margins ciliate or not, hairy. Flowers ± horizontal to slightly declinate; calyx divided 1/2–2/3 length, broadly campanulate, 1.5–4 cm, somewhat larger in fruit, lobes triangular or triangular-ovate, apices acute to subcaudate, surfaces hairy, nectaries absent; corolla funnelform to broadly so, petals pink or white, sometimes with red spot basally, narrowly to broadly, obliquely obovate, 4–12 × 3.5–6.5 cm, margins repand, sometimes undulate, minutely hairy abaxially mostly where exposed in bud; staminal column straight, white or cream, 1.2–5 cm, to 1/2 as long as petals, bearing filaments nearly throughout, free portion of filaments not secund, 2–8 mm; pollen yellow; styles white, 10–40 mm; stigmas creamy white to yellow. Capsules dark-brown, ovoid to subglobose, 1.4–3.5 cm, apex apiculate, glabrous or hairy. Seeds brown, reniform-globose, 2.5–3 mm, verrucose-papillose. 2n = 38.
