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]
