Heuchera alba

This species, described by Rydberg at the turn of the 20th century but only recently recognized as distinct, appears to be sister to Heuchera pubescens. It is a high-elevation Appalachian species that replaces H. pubescens northwards in West Virginia and a few adjacent states. It differs in the higher orientation of the flowers (not pendent, but about 30 or 45 degrees below horizontal) and the greenish-white color of the flowers. The third and fourth pictures were taken at a good angle to show the floral orientation properly. The petals are proportionally smaller and more incurved.
