Plants 1–3 m. Stems erect to sprawling, glabrous or sparsely retrorse-bristly when young and with black, sessile glands; spines at nodes sometimes absent or 1(–3), 1–8(–12) mm; prickles on internodes usually absent. Leaves: petiole (0.4–)1–5.5 cm, tomentose to pilose, with few longer, slender, stipitate-glandular hairs; blade broadly ovate or pentagonal, 3–5-lobed, cleft nearly 1/2 to midrib, sometimes lateral lobes again less deeply cut into larger distal and smaller proximal segments, 1.5–8 cm, base rounded to broadly cordate, surfaces glabrous, sparsely pubescent, or pilose-villous, usually ciliate, lobes acutish or oblong-rounded, margins deeply crenate-serrate or coarsely round-toothed, apex acute or rounded. Inflorescences pendent, solitary flowers or 2–5-flowered racemes, 1.5–3.5 cm, axis glabrous, flowers evenly spaced. Pedicels not jointed, (1.5–)2.3–5.5(–8) mm, glabrous; bracts ovate, 1–3 mm, glandular-ciliolate. Flowers: hypanthium green or greenish white, narrowly tubular to tubular-campanulate, 1.5–3.5 mm, glabrous or densely pilose to arachnoid-pubescent adaxially; sepals not overlapping, spreading to curved-reflexed (extended in fruit), white or greenish to purplish or reddish margined or tinged, oblong or oblong-lanceolate to narrowly lanceolate, 2.5–5 mm; petals connivent, erect, whitish or pinkish, broadly cuneate-obovate or cuneate-flabellate to cuneate or oblong, not conspicuously revolute or inrolled, 1–2.3 mm; nectary disc not prominent; stamens nearly 2 times as long as petals; filaments linear, 1.8–3.1 mm, mostly glabrous; anthers cream, ovate, 0.6–1.1 mm, apex with cup-shaped gland; ovary glabrous; styles connate 1/3–3/4 their lengths, 4.5–7 mm, proximally pilose-villous to middle or throughout. Berries palatable, greenish or reddish purple to gray-black, nearly globose or globose, 7–11 mm, glabrous. 2n = 16.
Distribution
w North America.
Discussion
Varieties 2 (2 in the flora).
Ribes inerme has strikingly pilose-villous styles that are sometimes green proximally and reddish distally, with the stigmas sometimes dark green.
