Bidens laevis is a species of flowering plant in the daisy family known by the common names bur-marigold and smooth beggarticks. It is native to the southern half of the United States, where it grows in wetlands, including estuaries and riverbanks. It is similar in appearance to its relative Bidens cernua and the two are sometimes confused. This is an annual or perennial herb growing over 20 centimeters tall and sometimes much taller, exceeding one meter in height and sometimes approaching two. The narrow lance-shaped leaves are 5 to 15 centimeters long, with finely toothed edges and pointed tips. The flower cluster bears one or more flower heads which bend down as they become heavy with fruit after flowering. Each head has a center of yellow disc florets and a fringe of 7 or 8 yellow ray florets each up to 3 centimeters long. The fruit is a sharply barbed achene.
