Boechera yorkii

About

Boechera yorkii is a rare species of flowering plant in the mustard family known by the common name Last Chance rockcress. It is endemic to Inyo County, California, where it is known only from the Last Chance Range in Death Valley National Park. There are only two occurrences known, but the plant occurs in remote, nearly inaccessible mountain territory, so more plants may exist unobserved. The species was only described to science in 2004. Its habitat is rocky mountain canyons on cliffs of dolomite.
