| Description: | Shrubby; branches, petioles, and peduncles thinly stellato-pubescent; leaves on long petioles, roundish-cordate, obtusely 3–5- angled, crenate 5–7-nerved, velvetty and sprinkled with hairs; stipules subulate; peduncles axillary, shorter than the petiole; invol. of 5, broadly-spathulate, cuspidate and bristle-pointed many-nerved leaflets, about as long as the calyx; capsule ovate-acuminate, tomentose. A shrub, with slender, sub-simple branches and sub-distant leaves, pretty constant in shape and pubescence. The invol. leaflets are remarkable in form, and in their pungent points; and serve to distinguish this species from H. ludwigii, its nearest ally. Cavanille's figure, except that it shows an infantile corolla, is very good. The mature flowers are large, yellow, with a dark-red centre. (from JSTOR Global Plants website / Flora Capensis) Shrub or perennial herb up to 3 m tall; stems tomentose or pubescent when young, later glabrescent. Leaf-lamina up to 12 × 12 cm, suborbicular in outline, obscurely or distinctly 3–5-lobed, stellate-pubescent or stellate-pilosulose above, stellate-pubescent or stellate-pilose or stellate-tomentose beneath, apex acute, margin serrate, base cordate or subcordate; petiole usually up to 9 (18) cm long, stellate-pilose; stipules up to 15 mm long, filiform or subsetaceous, somewhat expanded at the base. Flowers up to 12 cm in diam., yellow usually with a brownish or dark red centre, solitary, axillary; peduncle c. 7 (10) mm long, stellate-pubescent, usually rather inconspicuously articulated near the base. Epicalyx of 5 bracts, stellate-pubescent; bracts up to 18 mm. long, varying greatly in shape but nearly always broadest near the middle then narrowed suddenly to a caudate tip which is a prolongation of the midrib, joined for 3–4 mm at the base. Calyx up to 16 mm long, stellate-tomentellous; lobes ovate to ovate-lanceolate, usually 3-nerved, joined to nearly half-way. Petals up to 6 × 4.5 cm, obliquely obovate, pubescent outside, glabrous within. Staminal tube up to 15 mm long; free parts of filaments 1.5–3 mm long. Style-branches 4–5 mm long.
