Ribes malvaceum
Ribes erythrocarpum
Ribes malvaceum occurs in the southern North Coast, South Coast, Transverse, and Peninsular ranges, and the Channel Islands. It has also been reported from the Sierra Nevada in Tuolumne County. Its thick, rugose leaves, which are white-tomentose abaxially and dark green adaxially, and glaucous, white-haired berries are striking. Plants with dark green leaves occurring below 800 meters have been recognized as var. malvaceum, those with bright green leaves occurring up to 1500 meters as var. viridifolium.

Of conservation concern.
Ribes erythrocarpum is found in the Cascade Mountains of southern and central Oregon. It was allied with R. viscosissimum and R. sanguineum by A. E. Senters and D. E. Soltis (2003), with R. acerifolium (as R. howellii) and R. cereum by W. Messinger et al. (1999), and with R. glandulosum by M. Weigend et al. (2002). Ribes erythrocarpum shares fairly shallow hypanthia and conspicuous nectary discs with R. acerifolium,R. laxiflorum, and R. glandulosum.
