Petiole 2-8 cm; leaf blade circular or transversely elliptic in outline, 2-10 X 3-13 cm, palmately deeply divided; segments (3-)5-9, elliptic or oblong, tapered at both ends, densely pubescent, apex mucronate. Inflorescences capitate, few flowered; peduncle 4-11 cm; bracts hirsute; outer involucral bracts oblong to linear-oblong, 2-2.5 cm; inner bracts smaller. Pedicel obsolete. Sepals lanceolate, slightly unequal, 1-1.4 cm, hirsute on both sides. Corolla white, funnelform, 3-4 cm, midpetaline bands sparsely pubescent. Stamens included; filaments glabrous. Pistil included; ovary 2-loculed, glabrous. Stigma 2-lobed. Capsule ovoid, ca. 7 mm, 4-valved. Seeds ellipsoid, ca. 4 mm, gray tomentellous. 2n = 28, 30.
Pink or red-purple flowers 1 in. or more long in pedunculate bracteate heads.
Corolla white, pink or purple with darker throat, funnel-shaped, 3.5–5 cm. long; midpetaline areas with a few hairs.
