Discussion | Ribes niveum was thought to be extirpated in Colorado; it was rediscovered near Cañon City, Fremont County (T. W. Chumley and R. L. Hartman 2000). It is unusual in having anthers glabrate or finely pilose or arachnoid, closing and extended in fruit. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
