[Wikipedia] Range, Habitat, Etymology, Family Move: Lewisia brachycalyx is a species of flowering plant in the family Montiaceae, known by the common name short-sepal bitter-root or shortsepal lewisia.[1] It is native to the mountains of the southwestern United States and Baja California,[1] where it grows in moist habitat such as meadows. The Latin specific epithet brachycalyx means “having a short calyx”. The genus Lewisia was moved in 2009 from the purslane family (Portulacaceae) with adoption of the APG III system, which established the family Montiaceae. (link added by Mary Ann Machi)
