Helianthus praetermissus is a rare and probably extinct North American species of sunflower, with the common names New Mexico sunflower[1] and "lost sunflower." It is known from only one specimen collected in 1851 in Cibola County in western New Mexico, and not seen since.[2][3]
Helianthus praetermissus is (was?) an annual herb with a slender, unbranching stem 90 cm (3 feet) tall. It has (had) a single flower head with yellow ray florets surrounding red disc florets.[3]
