Flaveria oppositifolia is a rare Mexican plant species of Flaveria within the family Asteraceae. It has been found only in northeastern Mexico, from Tamaulipas west to Coahuila, south as far as Hidalgo and Aguascalientes. [2] Some sources report the species to be present in the State of Texas in the United States, but the Texas populations have been recognized as a distinct species, F. brownii. [3]

Flaveria oppositifolia is a perennial herb up to 80 cm (31.5 in) tall. Leaves are about 5–10 cm (2–4 in) long, covered in short, soft hairs. One plant can produce numerous flower heads in a loose branching array. Each head contains 10-15 yellow disc flowers but no ray flowers. [2]
