Helianthus simulans is a North American species of sunflower known by the common name muck sunflower. It is native to the southeastern and south-central United States, from eastern Texas to the Carolinas. There are some suggestions that the populations in the eastern half of that range might represent naturalizations. Helianthus simulans grows in wet, mucky soils in marshes, ditches, and roadsides. It is a perennial herb up to 260 cm (over 8 feet) tall, spreading by means of underground rhizomes. One plant usually produces 1-15 flower heads, each containing 12–23 yellow ray florets

Helianthus praetermissus is a rare and probably extinct North American species of sunflower, with the common names New Mexico sunflower and lost sunflower. It is known from only one specimen collected in 1851 in Cibola County in western New Mexico, and not seen since. 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.
