Dudley Bluffs Bladderpod (Physaria-congesta), Mustard Family (Brassicaceae). An endemic species (critically imperiled globally and in Colorado G1 S1) in the Piceance Basin in Rio Blanco County which grows on barren white shale slopes, with pinyon-juniper in the foothills on the west slope. Blooms in April and May. There are seven documented populations of this species. Mining and oil and gas development are considered to be the primary threats to the species.
