Amphipappus is a North American genus in the family Asteraceae. It is native to desert regions of the southwestern United States, in southern California, southern Nevada, Arizona, and southeastern Utah.[2][3]

There is only one known species Amphipappus fremontii. It is a shrub up to 60 cm (23.5 in) tall. The flower heads are yellow and have both ray florets and disc florets. Its rounded clumps are scattered about dry, rocky areas.[4]

The species takes its scientific epithet, fremontii from John C. Frémont,[5] and is known commonly by the names chaffbush or eytelia (in honor of artist Carl Eytel).[6][7]
