beggar-ticks
Bidens pilosa L.
Bidens pilosa L. is an annual herbaceous flowering plant in the daisy family Asteraceae. It is known by several common names, including beggar-ticks, hitch hikers, black-jack, and cobblers pegs. Native to the Americas, it has spread as an introduced species across Eurasia, Africa, Australia, South America, and the Pacific Islands. In some regions, it is considered invasive. The species was first described in 1753.
Description
Bidens pilosa is found in various regions including British Columbia, Ontario, Quebec, Açores, Madeira, Portugal Continental, and several islands in the Azores and Caribbean. The name was discussed by Sherff in 1937, who did not designate a type specimen, but D'Arcy later proposed 975.8 (LINN) as the type, a choice followed by many subsequent authors. The plant is commonly called beggar-ticks and is recognized for its widespread distribution and potential to become invasive in non-native habitats.
