What appears to be nesting saxifrage as seen at left along a small vernal stream spilling over the west rim of the Klickitat River canyon, Klickitat Canyon NRCA.........May 1, 2015. I believe the leaf blades were glabrous and longer than their petioles. The photo at right shows the flowers of nesting saxifrage as seen along Rd 6000 at a moist, rocky meadow near 2780' on the southeast side of Mt. Adams.........May 14, 2005.

Basal leaf of Brittle-leaved Saxifrage, Fleshy-leaved Saxifrage, Peak Saxifrage, Swamp Saxifrage: Saxifraga nidifica var. claytoniifolia (Synonyms: Micranthes fragosa, Saxifraga claytoniifolia, Saxifraga fragosa, Saxifraga fragosa ssp. claytoniifolia, Saxifraga fragosa var. fragosa, Saxifraga integrifolia var. claytoniaefolia, Saxifraga integrifolia var. claytoniifolia)

The photo above shows the basal leaves of nesting saxifrage as seen along Rd 6000 at a moist, rocky meadow near 2780' on the southeast side of Mt. Adams........May 6, 2006. Note how the base of the leaf tapers somewhat gradually into the petiole. A leaf base that tapers much more gradually would be Micranthes integrifolia. One that tapers abruptly would be Micranthes fragosa.
