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 (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. |

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 reflexed, 5–18-flowered racemes, 3–7 cm, axis glabrous, finely pubescent, or densely villous, 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, 2–8 mm, glabrous or densely villous; bracts broadly deltate to obovate (similar to leaves), 4–9 mm, glabrous or densely villous. |
||||||||||||
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 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. |

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.) |
Varieties 3 (3 in the flora). Ribes aureum was introduced into cultivation in Europe early in the nineteenth century (F. V. Coville 1903). It is a major host of pinyon blister rust in Arizona, Colorado, and Utah, and of pinyon leaf rust in New Mexico (E. P. Van Arsdel and B. W. Geils 2004). Ribes aureum is a variable complex and the varieties may seem to intergrade. In California, var. aureum occurs in sagebrush scrub or coniferous forests at higher elevations (800–2600 m) than var. gracillimum; the sepals of var. aureum are longer than those of var. gracillimum (5–8 mm versus 3–4 mm), and its hypanthium is noticeably shorter relative to the sepals. Leaves of var. aureum are more highly lobed and are sparsely glandular in the Pacific Northwest and less lobed and more densely glandular in the southwest (H. D. Hammond, pers. comm.). In most of its range, var. villosum is so conspicuously villous as to be unmistakable; in the west some plants with strikingly long hypanthia are scarcely villous.
