Discussion

Ribes watsonianum occurs in the Cascade Range of Oregon, Washington, and British Columbia, and in Alberta. Analysis of combined datasets of ITS, ETS, psbA-trnH, and chloroplast restriction sites placed R. watsonianum as sister to sect. Grossularia (L. M. Schultheis and M. J. Donoghue 2004).
