The fruits of red-flowered currant are edible, but not particularly palatable - it's best to leave them for the birds. Other gooseberries and currants are better choices for those with an appetite.
The family for Ribes, the Grossulariaceae, is an “exception to a rule” of botanical nomenclature. In most instances, the name of a plant family is based off the name of a valid genus within the family, e.g., Rosaceae and Rosa or Salicaceae and Salix. However, even though the genus Grossularia is no longer recognized as a separate taxonomic entity, the Grossulariaceae as a family name has been nomenclaturally “conserved” due to (I'm assuming with these) long-standing use of the name and the anticipated disruption a change in the name would cause.
Botany resource links: The online Atlas of Canada has several ecological maps of interest to Canadian botanists, including maps of Endemic Plant Diversity and Rare Plant Diversity.
I know this is unlikely to get a response two years after the original post, however...
Daniel, if what you assume is true about the retention of the name Grossulariaceae, how does that jive with the change of Compositae to Asteraceae?
The answer to that is in section 18.5 of the International Code of Botanical Nomenclature (Vienna - 2006):
“The following names, of long usage, are treated as validly published: Compositae (Asteraceae; type, Aster L.); ”.
Grossulariaceae is retained under the rules of section 18.3.
