''Ribes'' species are medium shrublike plants with marked diversity in strikingly diverse flowers and fruit. They have either palmately lobed or compound leaves, and some have thorns. The

there has been contradictory evidence. Although sometimes treated as two separate genera, ''Ribes'' and ''Grossularia'' (Berger 1924), the consensus has been to consider it as a single genus, divided into a number of

, the main ones of which are subgenus ''Ribes'' (currants) and subgenus ''Grossularia'' (gooseberries), further subdivided into sections. Janczewski (1907) considered six subgenera and eleven sections. Berger's twelve subgenera based on two distinct genera (see Table 1) have subsequently been demoted to sections. Weigend (2007) elevated a number of sections to produce a taxonomy of seven subgenera; ''Ribes'' (sections ''Ribes'', ''Heretiera'', ''Berisia'') ''Coreosma'', ''Calobotrya'' (sections ''Calobotrya'', ''Cerophyllum''), ''Symphocalyx'', ''Grossularioides'', ''Grossularia'', ''Parilla''.
