Claytonia saxosa is a species of wildflower in the purslane family known by the common name Brandegee's springbeauty. It is endemic to California, where it is known from the rocky, barren serpentine slopes of the Klamath Mountains and North Coast Ranges. This is a small, compact annual herb forming clumps a few centimeters wide in rock crevices. The leaves are small, fleshy, and generally red in color, packed densely together about the short stem. Two to ten flowers emerge from the clump, each with five light pink petals under a centimeter long.
