Adeia whitneyi, common name Whitney's bristleweed,[3] is a North American species of shrub in the daisy family.

[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.

[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.
