System
The Oregon gooseberry (Ribes divaricatum ) is a species of the genus currants (Ribes ) in the family of gooseberry plants ( Grossulariaceae ). It is assigned in the subgenus Grossularia the section Grossularia. The species was described in 1830 by David Douglas for the first time scientifically. The genus name Ribes derives from the Arabic name of a species of rhubarb. The name was adopted in the Middle Ages because of the sour taste of the berries of some species, reminiscent of the taste of rhubarb, for the currants. The specific epithet divaricatum comes from the Latin and means " bulky ".
