Helianthus praetermissus |
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]
