| Discussion | Varieties 2 (2 in the flora). Ribes sanguineum is widely cultivated. It begins to bloom very early in the season, providing a nectar source for pollinators when little else is available. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Ribes acerifolium K. Koch (1869), which was believed to block the use of R. acerifolium Howell, was not validly published. Consequently, the name R. howellii Greene, proposed as a substitute name, is superfluous; it appears in many floras and on many herbarium specimens.
