Habit Plants 1–4 m. Stems erect, finely pubescent, 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 2–7 cm, puberulent, short stipitate-glandular;

blade broadly reniform or cordate-orbiculate to deltate-ovate, nearly equally to irregularly 5-lobed, cleft nearly 1/4 to midrib, 2–7 cm, base subtruncate to cordate, surfaces puberulent to whitish-tomentose abaxially, puberulent adaxially or puberulent and colorless, sessile-glandular on both surfaces, lobes deltate to obtuse, margins finely 2–3 times crenate and denticulate or serrate, apex broadly acute.

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 to stiffly spreading or ascending or erect, 5–40-flowered racemes, 5–15 cm, axis crisped-pubescent and stipitate-glandular, flowers evenly spaced.

nectary disc not prominent;

stamens shorter than to as long as petals;

filaments linear or slightly expanded at base, 1.2–2 mm, glabrous;

anthers cream, oblong-oval, 0.5–0.8 mm, apex shallowly notched;

ovary stipitate-glandular to strongly stipitate-glandular and crisped-puberulent;

styles connate nearly to stigmas, 4–6 mm, glabrous or with scattered, stipitate glands at base.

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;

Berries

palatable but insipid, blue-black, glaucous, ovoid or globose, 3–9(–10) mm, yellowish or greenish stipitate-glandular.

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

Discussion

Varieties 2 (2 in the flora).

Ribes sanguineum is widely cultivated. It begins to bloom very early in the season, providing a nectar source for pollinators when little else is available.

(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.
