This is one of the less common Missouri species of Ribes, occurring in scattered counties in the eastern half of the state. When in flower or fruit, it is easily distinguished from the much more common R. missouriense by its spinescent ovaries and fruits. Also, the flowers do not have the long-exserted stamens which give flowers of R. missouriense their unusual appearance. The leaf petioles are also glandular.
The fruits of this species are edible and tasty, though must be sampled with care! (Thanks to Claire for her intrepid leadership in taste tests.)
