Habit | Plants 0.2–2 m. | Plants (not strong-smelling), 0.5–1.5 m. | ||||
Stems | spreading or arching to erect, puberulent, sparsely to copiously stipitate-glandular; 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 3–6 cm, glabrous; blade suborbiculate, 5-lobed, cleft 1/3–1/2 to midrib, 2.5–4.5 cm, base truncate to cordate, surfaces not glandular, sparsely hairy on veins abaxially, glabrous adaxially, lobes broadly ovate-triangular, margins bicrenate-serrate, apex 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. |
ascending to pendent, 8–20-flowered racemes, 2–6 cm, axis glabrous, not glandular, flowers evenly spaced. |

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.) |
The leaves of Ribes rubrum are rather thick. Cultivated red currants may have originated from a cross between R. rubrum and R. spicatum E. Robson, a rare species native in northern Britain (R. Mabey 1996). Many of the state and province records of occurrence may be the result of repeated escape from cultivation rather than true naturalization.
