Claytonia rubra is a species of wildflower in the family Montiaceae known by the common names redstem springbeauty and erubescent miner's lettuce. It is native to western North America from southwestern Canada to the United States of America extending from The Black Hills and western slopes of the Rocky Mountains to the Cascade and Coast Range, Ochoco and Wallowa Mountains south to the Warner Mountains, Yolla Bolly Mountains, and Sierra Nevada and Transverse Ranges [Mt. Pinos and Mt. San Gorgonio], where it is found in coniferous forests and shrublands.[1] This is an annual herb with stems up to about 15 centimeters long. Some individuals may overwinter as biennials. The basal leaves have small rounded to diamond-shaped blades on long, tapering petioles. There are also leaves on the stem which may be rounded or squared and sometimes fuse together to create a bowl around the stem. All the leaves possess blunt (obtuse) tips according to published descriptions and taxonomic treatments. The herbage is red or pink in color at all stages of development. The inflorescence is a dense cluster of up to 30 tiny flowers, each with petals less than 4 millimeters long and white to pink-tinted in color. Together with Claytonia perfoliata and Claytonia parviflora, Claytonia rubra comprises what is almost certainly a polyploid pillar complex based on three diploid species, each occupying a definitive ecological niche.[2]
