Bidens lemmonii

Bidens lemmonii (Lemmon's beggarticks)[1] is a North American species of flowering plant in the daisy family. It is native to the southwestern United States (Arizona, New Mexico)[2] and Mexico (Sonora, Chihuahua, Durango, Sinaloa, Michoacán, Baja California, Baja California Sur).[3]

Bidens lemmonii is an annual herb up to 30 cm (12 inches) tall. It produces flower heads sometimes one at a time, sometimes in a group of several, each containing yellow disc florets and (usually) white ray florets. The species grows in wet seeps on rocky mountainsides.[4]

The species is named for John Gill Lemmon (1831 or 32-1908), husband of American botanist Sara Plummer Lemmon (1836–1923).[5]
