Ribes oxyacanthoides

Northern Gooseberry

Early Fruit and Leaves

Good Spirit Lake Provincial Park

There are spines at the nodes, and prickles on the internodes.

The Ribes genus was previously placed within a traditional version of the Saxifragaceae family which included a great many diverse genera.  That version of the Saxifragaceae family is now considered to be polyphyletic, and the family is now much reduced.  Ribes has been moved to a new family called Grossulariaceae, within which Ribes is the only genus.  Budd's Flora (1987) still places Ribes in Saxifragaceae, while Flora of Alberta (1994) places it in Grossulariaceae.
