A silvery plant with a basal rosette of leaves and prostrate to erect stems with upturned tips bearing dense racemes of yellow flowers.

Found in dry, rocky or gravelly areas in arid shrublands, aspen forests, coniferous forests and alpine tundra. It's range includes WY, UT and CO, mostly within the drainage plain of the Colorado River.

Physaria derives from the Greek physa, meaning 'bellows', refering to the swollen pod halves.
