Cardamine constancei
Cardamine constancei is a rare, narrow-ranged species of perennial rhizomatous forb known by the common name Constance's bittercress. It is endemic to select tributaries of the Clearwater and Coeur d'Alene Rivers in Idaho.
Constance's bittercress is endemic to the Clearwater Mountain range in north-central Idaho. Populations have been found around the North and Middle Forks of the Clearwater River and throughout the Selway, Coeur d'Alene, and St. Joe River canyons in Clearwater, Idaho, Kootenai, Nez Perce, and Shoshone Counties in Idaho. It is most commonly found around the Selway River. The species is fairly abundant throughout its limited range, but is sensitive to human disturbance. The ability of the plant to spread and set seed is limited by soil moisture levels.
