basal and cauline; petiole ± flattened, 10–70 mm, (± hairy); blade reniform, 5–7(–11)-lobed (lobes obtuse, sometimes acute), (5–)7.4–11.2(–20) mm, slightly fleshy, margins entire, sparsely glandular-ciliate or eciliate, apex rounded to obtuse, surfaces glabrous or sparsely short stipitate-glandular. |
Inflorescences | 3–6-flowered cymes, 2.5–12 cm, pink- to purple-tipped stipitate-glandular; bracts sessile. |
2–6(–29)-flowered, capitate thyrses, sometimes solitary flowers, (flowers subsessile), (3–)5–15(–18) cm, densely tangled, reddish brown-hairy; bracts (5–10), petiolate, (3–7-lobed, densely surrounding inflorescence). |
Flowers | sepals erect, ovate to oblong, margins sparsely ciliate, surfaces glabrous; petals white to cream, yellow-spotted proximally, red- or orange-spotted distally, these often faded in dried specimens, elliptic, 4–6 mm, much longer than sepals; ovary superior. |
