Adeia whitneyi, common name Whitney's bristleweed,[3] is a North American species of shrub in the daisy family. It has been found only in the state of California in the western United States.[1][4][5]
Adeia whitneyi is a perennial herb or subshrub up to 50 cm (20 in) tall. The plant produces numerous flower heads in a dense, elongated array at the top of the plant. Each head contains 8-10 disc flowers but no ray flowers. The species sometimes grows on serpentine soils.[6]
The species was first named Haplopappus whitneyi in 1868 by Asa Gray.[1] In 2021 Guy L. Nesom placed the species into the new genus Adeia and elevated its former subspecies discoidea to a distinct species, Adeia discoidea.[7]
