Comments: New Mexico Plumeseed or Desert Chicory is a showy conspicuous spring bloomer of the lower deserts following adequate winter rainfall. In Southwest Desert Flora also see two similar species are California Plumeseed, Rafinesquia californica and Tackstem, Calycoseris wrightii. In Arizona California Plumeseed is less abundant in distribution and has smaller flower heads. Tackstem is found in the same habitats but it has visible tack-shaped glands under the flower heads.

The common name of Desert Chicory is adapted from its similarity to Common Chicory, Cichorium intybus which is bright blue and found throughout Arizona and the United States.
