    • n bidens A genus of herbaceous composite plants, closely related to Dahlia and to Coreopsis, having achenes armed with two or more rigid, persistent, retrorsely barbed awns. They are coarse, useless weeds, but some of the species have conspicuous yellow flowers and are known as bur-marigolds. The persistency with which the achenes adhere to clothing and the coats of animals has given rise to the common name of beggar's-ticks or beggar's-lice. The root and seeds of B. bipinnata, known as Spanish needles, have had an ill-founded reputation as emmenagogues and as a remedy for acute bronchial affections.
    • n bidens In zoology, a genus of hawks with two-toothed beak; same as Diodon or Harpagus (which see). Spix, 1834.
