Ribes triste

Swamp Red Currant

Leaf Bottom

Good Spirit Lake Provincial Park

Note the petiole is flattened and winged at the base.

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.  Budd's Flora refers to this species as R. rubrum.

bulletplants green; NOT [plants white, pink or reddish brown]
bulletplants unarmed; NOT [plants armed with prickles, spines or thorns]
