Habit Plants 0.2–2 m. Stems spreading or arching to erect, puberulent, sparsely to copiously stipitate-glandular; spines at nodes absent; prickles on internodes absent. Plants 0.5–1.5 m. Stems erect to spreading, crisply puberulent to villous, glandular throughout with yellow, shiny, sessile, crystalline, round glands; spines at nodes absent; prickles on internodes absent.
Leaves

petiole (0.3–) 0.6–1.2(–2.8) cm, glabrous or finely to copiously pubescent;

blade almost reniform to broadly cuneate-flabellate, 3–5(–7)-lobed, shallowly cleft, (0.5–) 1–2(–4) cm, base cordate to truncate, surfaces glabrous or copiously pubescent, sparsely stipitate-glandular to downy to conspicuously stipitate-glandular and sessile-glandular, particularly noticeable on margins, lobes rounded, margins coarsely crenate-dentate, apex obtuse.

petiole 1–7 cm, (equaling or shorter than blade), crisply puberulent to villous, with slender processes along proximal margins;

blade pentangular, 3–5-lobed, cleft nearly 1/2 to midrib, (1.5–)2–7 cm, base broadly truncate to shallowly cordate, surfaces with amber, sessile glands, thickly villous at least abaxially or along abaxial veins, lobes broadly deltate, margins usually coarsely bicrenate-serrate, apex acute to bluntly acute.

Inflorescences

pendent, solitary flowers or 2–8(–9)-flowered racemes, 1–3 cm, axis finely pubescent, ± sticky with short-stalked to subsessile glands, flowers tightly clustered at end of peduncle.

spreading to pendent, 6–15-flowered racemes, 1.5–5 cm, axis pubescent, flowers evenly spaced.

Pedicels

jointed, (0.4–)1–2.2(–3.4) mm, puberulent;

bracts flabellate or ovate to obovate, 3–7(–8.8) mm, pubescent, stipitate-glandular.

jointed, 0.1–2 mm, villous;

bracts narrowly lanceolate, to 10 mm, villous to sparsely hairy.

Flowers

hypanthium white to greenish white with pink tinge, or pinkish white, narrowly tubular, tube widest at base and near throat, 5–9(–9.4) mm, densely hairy and scattered stipitate-glandular abaxially, glabrous adaxially;

sepals not overlapping, spreading-recurved, greenish white to white or faintly to strongly pinkish tinged, deltate-ovate, 1–3.2 mm;

petals connivent, erect, white to pink, orbiculate or flabellate, not conspicuously revolute or inrolled, 1–2.1 mm;

nectary disc not prominent;

stamens shorter than petals, (inserted below petals and completely included in hypanthium tube);

filaments linear, 0.5–1.6 mm, glabrous;

anthers pale cream-yellow to yellow, oval, 0.6–1.2 mm, apex with small, cup-shaped gland;

ovary glabrous or hairy or sparsely to densely pubescent;

styles connate nearly to stigmas, 7.5–11.5 mm, proximally hairy or glabrous.

hypanthium green, broadly tubular-campanulate, 3–4.5 mm, glabrous or sparsely villosulous;

sepals not overlapping, usually reflexed, cream to greenish white, narrowly oblong-spatulate to nearly oblong, 4.5–5 mm;

petals connivent, erect, whitish, oblong to oblong-obovate, not conspicuously revolute or inrolled, 2.5–3 mm;

nectary disc not prominent;

stamens nearly as long as petals;

filaments expanded at base, 1 mm, glabrous;

anthers cream, oval, 1 mm, apex with small-holed callus;

ovary glabrous;

styles connate nearly to stigmas, 6–8 mm, glabrous.

Berries

tasteless, dull to bright red or orange-red, ovoid, 5–12 mm, sparsely glandular to glandular.

palatable when cooked, black, ovoid, 10 mm, glabrous, without resinous glands.

Discussion

Varieties 2 (2 in the flora).

Ribes cereum has a notably spicy odor. The bright green style, which becomes brown with age, is striking.

(Discussion copyrighted by Flora of North America; reprinted with permission.)

Fresh material of Ribes americanum does not have the skunklike odor of R. hudsonianum and R. nigrum. The bracts are much longer than the jointed pedicels. The leaves and bracts bear fimbriate processes on the proximal margins that may be remnants of adnate stipules.
