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.) |
Of conservation concern. Ribes binominatum occurs at relatively high elevations in the Coast Ranges of northern California and the Klamath Mountains of central and southern Oregon. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
