Rafinesquia neomexicana (New mexico plumeseed)
Anderson, Wynn

Rafinesquia neomexicana

Rafinesquia neomexicana A. Gray

New Mexico Plumeseed, Plume-seed

Asteraceae (Aster Family)



USDA Native Status: L48 (N)

A smooth, sparsely-leaved, grayish-green plant with white flower heads at the ends of the few branches. Sap milky.

The genus name honors C. S. Rafinesque, an eccentric early naturalist. Two similar species in the same region are California Plumeseed (R. californica), with smaller heads and the stalk on the fruit longer than the body, and Tackstem (Calycoseris wrightii), with tack-shaped glands beneath the head.
