Description
editChaenactis evermannii is a small perennial rarely more than 12 cm (5 inches) tall. Each branch produces 1-3 flower heads each containing disc florets but no ray florets.[4][5] It grows in subalpine, usually decomposing, granitic sand or gravel slopes, ridges, scree, talus, or above conifer forests.[4]
The species is named for American ichthyologist Barton Warren Evermann (1853–1932).[5]
