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.) |
Ribes pinetorum is the most important member of the genus within its range for spread of white pine blister rust (E. P. Van Arsdel and B. W. Geils 2004). The anthers are connivent, separating in age. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
