Ribes (family Grossulariaceae) A genus of shrubs with simple, alternate, usually palmately lobed leaves, and flowers in racemes. These are regular, with 4 or 5 sepals, petals, and stamens, and an inferior ovary of 2 carpels which forms a berry on top, of which the calyx persists. Many species are grown for their edible fruits (e.g. R. rubrum, redcurrant; R. nigrum, blackcurrant; and R. uva-crispa, gooseberry), or for their ornamental flowers. There are about 150 species, occurring in the northern temperate zone, and on the mountains of Central and S. America.
