Micranthes odontoloma

Micranthes odontoloma is a species of flowering plant known by the common name brook saxifrage. It is native to much of western North America, where it can be found in many types of moist and rocky habitat types. It is a perennial herb growing from a caudex and rhizome system. It produces a clump of leaves with rounded, toothed, or scalloped blades on long, thin petioles. The branching inflorescence arises on a slender, erect peduncle up to half a meter tall bearing many flowers. Each flower has five teardrop-shaped white petals with threadlike bases, and stamens with flat, narrow filaments that sometimes resemble additional petals.
