petiole 2–10 cm, sparsely pubescent;

blade ovate, deeply 5–7-lobed, cleft 1/2+ to midrib, (1.5–)2–10(–22) cm, base cordate, surfaces with yellow, dull, sessile glands and sparse hairs abaxially, with yellow, shiny, sessile glands and glabrous adaxially, lobes with main segments ovate-lanceolate, margins 1–2 times sharply serrate, apex acute, shallowly lobed.

petiole (0.4–)1–3(–4.8) cm, margins of young leaves often with slender extensions like multicelled hairs, surfaces finely pubescent, glabrescent;

blade broadly deltate-ovate to obovate, 3(–5)-lobed, cleft less than to slightly more than 1/2 to midrib (sometimes proximal leaves again shallowly lobed), (1–)1.6–3.6(–5.7) cm, base broadly cuneate to somewhat cordate, surfaces sometimes with colorless or yellowish, nearly sessile glands, finely pubescent or glabrous, glabrescent, lobes oblong-rounded, margins entire or with 2–5 rounded teeth, apex acute to obtuse.

ascending to erect, 20–50-flowered racemes, (10–)15–30 cm, axis sparsely pubescent, flowers evenly spaced.

ascending to reflexed, 5–18-flowered racemes, 3–7 cm, axis glabrous, finely pubescent, or densely villous, flowers evenly spaced.

jointed, 5–12 mm, pubescent and glandular;

bracts conspicuous, proximal ones ovate, lobed, distal ones narrowly oblong, unlobed, (3–)4–5 mm, sparsely glandular and pubescent.

jointed, 2–8 mm, glabrous or densely villous;

bracts broadly deltate to obovate (similar to leaves), 4–9 mm, glabrous or densely villous.

hypanthium green, saucer-shaped, widely flared, 0.5–1.5 mm, ± pubescent and sparsely glandular abaxially, glabrous adaxially;

sepals nearly to somewhat overlapping, spreading, brownish purple to greenish or sometimes nearly white, ovate-lanceolate to oblong-lanceolate, 3–5 mm;

petals widely separated, erect, white, cuneate-flabelliform, not conspicuously revolute or inrolled, 1 mm;

nectary disc wine red, thick, lobed, covering and submerging ovary;

stamens slightly longer than petals;

anthers white, transversely oblong-cordate, 0.5 mm, broader than long, apex shallowly notched;

ovary somewhat hairy and densely sessile-glandular;

styles connate 1/4–1/2 their lengths, 1 mm, glabrous or hairy.

hypanthium yellow to yellowish green, narrowly tubular, 6–20 mm, glabrous;

sepals not overlapping, spreading, usually not reflexed, golden yellow, oblong-elliptic, 3–8 mm;

petals connivent, erect, yellow to orange or deep red, oblong-obovate, not conspicuously revolute or inrolled, 2–3(–4) mm;

nectary disc not conspicuous;

stamens nearly as long as petals;

filaments slightly expanded at base, 0.9–1.5(–2.2) mm, glabrous;

anthers white, oblong, 1.1–2 mm, apex minutely apiculate;

ovary glabrous;

styles connate almost to stigmas, (8.5–)9.8–12.5 mm, glabrous.
