Stephanomeria malheurensis

Stephanomeria malheurensis, the Malheur wirelettuce, is a species of flowering plant in the family Asteraceae. It is endemic to Oregon in the United States. It is a federally listed endangered species.

It was discovered in 1966 and the population at the type locality in Harney County is the only one ever known. For several years in the 1980s it disappeared. Scattered individuals have been noted over the years. Plants were grown from seed at the Berry Botanic Garden in Portland and planted at the original site. Some still survived as of 2001.
