Heuchera grossulariifolia

This species is quite common in river gorges of the Idaho Rockies and adjacent Montana. Disjunct populations in the Columbia Gorge have been treated as distinct at the varietal level. The name would appear to come from the deep leaf sinuses, resembling a typical Ribes (currant or gooseberry) leaf.

Heuchera grossulariifolia var. grossulariifolia

This variety is the more widespread of the two, mostly occurring in the river gorges of the Idaho Rockies and also in western Montana. It has creamy or white flowers and petals at least as long as the sepals. It is notable for containing diploid and tetraploid cytotypes (also known from H. micrantha and H. cylindrica, perhaps H. parvifolia and H. richardsonii), a fact that has made it the subject of several ecological studies.

Heuchera grossulariifolia var. tenuifolia

This variety may be distinguished from the typical one by the greener flowers and petals that are significantly shorter than the sepals. Sometimes the inflorescences have more flowers per cymule (cluster), but this does not seem to be stable. This plant occurs in the Columbia Gorge, mostly on the Oregon side; it is disjunct from the typical variety.
