Discussion | Varieties 3 (3 in the flora). Hybrids between Ribes divaricatum and R. niveum and R. divaricatum and R. lobbii have been propagated for the horticultural trade. (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.) |
