Leaves on very short stalks, rough on the upper surface, bristly beneath, polymorphous, lower ones roundish, upper ones palmately 3–5-parted; segments oblong-lanceolate, irregularly serrate. Stipules liguliform, persistent. Peduncles solitary, axillary, often as long as the nearly sessile floral leaves. Epicalyx of 8–10 distinct, liguliform, ciliolate segments. Calyx campanulate, 5-parted, its 5 lobes oblong-lanceolate or acuminate, exceeding the epicalyx. Corolla yellow, 1 1/2–2 in. diam., twice the size of the epicalyx. Capsule oblong-ovoid, slightly pointed, its 5 valves downy and hispid along their edges. Seeds smooth.
