A rayless, diploid (n = 4), shrubby, new species of Machaeranthera is described from gypsum dunes near Cuatro Ciénegas, Coahuila. It is most closely related to M. johnstonii , another rayless, shrubby, endemic gypsophile of this region. Machaeranthera restiformis often occurs with the wide‐ranging, white‐rayed species, M. gypsophila (n = 4) with which it occasionally hybridizes.
