Krameria bicolor is a perennial shrub or subshrub of the family Krameriaceae, the Rhatanies. It is commonly known as white rhatany, crimson-beak, and chacate in Spanish (cosahui in the state of Sonora). It is found in drier environments of the southwestern United States from California to Texas, and in northern Mexico. It is a low lying, densely branched shrub, commonly up to 2 feet (1 m), but exceptionally to beyond 5. 0 feet (2 m). The branches are spiny in form but not sharp nor firm at the tips. The leaves are grey-green to greenish, finely-haired, narrow and only one half to three quarters of an inch long.
