Bidens aristosa, known by many common names such as bearded beggarticks, western tickseed, showy tickseed, long-bracted beggarticks, tickseed beggarticks, swamp marigold, and Yankee lice, is an herbaceous, annual plant in the Asteraceae family. It is native to the central United States, but has been introduced to the eastern United States, Canada, France, Great Britain, and India. It grows in marshes, meadows, pine forests and disturbed sites.
Description
Bidens aristosa is a herbaceous, annual flowering plant that typically grows between 1-2 ft tall, but can grow up to five feet tall. The leaves are attached to petioles 1 to 3 cm long. The leaf blades are lanceolate to lance-linear, and are laciniately pinnatisect. It has numerous yellow flower heads with 5-10 ray florets and 12-40 disc florets. Fruits are dry cypselae bearing barbs that get caught in fur or clothing, thus aiding in the plant's dispersal.[3]
Distribution and habitat
This species can be found from the United States (Alabama, Arkansas, District of Columbia, Illinois, Indiana, Kentucky, Louisiana, Maryland, Michigan, Minnesota, Missouri, New York, North Carolina, South Carolina, Tennessee, Texas, Virginia, Wisconsin),[4] Canada (Ontario), France, Great Britain, and India.[2]
The species is most likely native to the Central United States, but has been introduced into the Eastern United States, Central Canada, France,[5] Great Britain, and India. The first sighting of Bidens aristosa in the eastern United States was by the Potomac River near Glen Echo, Maryland in 1902.[6] The species is likely spread by the import of food crops or wool products.[6]
Habitat
Bidens aristosa grows in marshes, meadows, pine forests and disturbed sites at elevations of 0 to 300 metres from sea level.[3]
Taxonomy
Bidens aristosa was first described by André Michaux under the name Coreopsis aristosa in 1803 in the publication Flora Boreali-Americana. In 1893, Nathaniel Lord Britton moved the species to the genus Bidens, while keeping the species epithet the same.[7]
