Discussion | Ribes amarum occurs in central and southern California and in the central Sierra Nevada southward. Plants from the Santa Ynez Mountains of Santa Barbara County with hairy fruits have been named var. hoffmannii. This species shares the apiculate, short-indehiscent anthers with other species in this group. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ribes mogollonicum is included here in R. wolfii because the two taxa, morphologically, seem to overlap completely. A. E. Senters and D. E. Soltis (2003) placed R. mogollonicum near R. viscosissimum and R. erythrocarpum. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
