Lithophragma affine
Lithophragma affine is a species of flowering plant in the saxifrage family known by the common name San Francisco woodland star or fringed woodland star.[1] It is native to the coast of western North America from Oregon to Baja California, where it grows in open habitat on mountain slopes, hills, and canyonsides[2] up to an altitude of 6,600 feet (2,000 m).[1] It is a rhizomatous perennial herb growing erect or leaning with a tall naked flowering stem. The leaves are located on the lower part of the stem, each divided into sharp-pointed lobes. The stem bears up to 15 widely spaced flowers, each in a cuplike calyx of red or green sepals. The five petals are bright white, up to 1.3 centimeters long, and divided into three toothlike lobes at the tips.[2] Depending on location, it blooms between late January and June.[1] References
