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 erythrocarpum is found in the Cascade Mountains of southern and central Oregon. It was allied with R. viscosissimum and R. sanguineum by A. E. Senters and D. E. Soltis (2003), with R. acerifolium (as R. howellii) and R. cereum by W. Messinger et al. (1999), and with R. glandulosum by M. Weigend et al. (2002). Ribes erythrocarpum shares fairly shallow hypanthia and conspicuous nectary discs with R. acerifolium,R. laxiflorum, and R. glandulosum.
