Megalodonta beckii (Torr. ex Spreng.) Greene
Bidens beckii is a perennial herb sometimes as much as to 200 cm (80 inches) tall; it grows emerging from stagnant or slow-moving water, the submerged leaves are finely filiform-dissected. The stem typically arises 15 cm above the water and its leaves are simple, oppositely arranged, lanceolate to ovate and serrated and borne directly from the stem with no petiole. It produces numerous yellow flower heads containing (10-30) disc florets and (8) ray florets in late summer. The flowers are solitary at the end of the stem and 2–2.5 cm in diameter. Below the flower there are 5-8 hairless bracts which are about half as long as the petals.
