Last in the series on the buttercup family and the last brief entry (for at least a couple weeks):
Clematis occidentalis var. grosseserrata, or western blue virginsbower, is restricted to western North America whereas a second variety, var. occidentalis is only found in eastern North America. A third variety, Clematis occidentalis var. dissecta occurs only in the Wenatchee Mountains and adjacent ranges in Washington state.
These photographs were taken the first time I encountered the species in the wild, sometime in early to mid-June.
