| 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 mescalerium occurs in the Sacramento and Guadalupe mountains of southeastern New Mexico and western Texas. It is distinguished from R. cereum in having thinner, larger, more deeply lobed leaves, and glands with relatively long stalks.
