Extract

The genus Bidens L. is in the Asteraceae (Compositae), the largest family of flowering plants, and one which contains many of the world's weed species. Beggarticks' phenomenal spread and colonization is due partly to their effective pollination mechanisms and their distinctive dispersal adaptations, which allow seed distribution by humans, animals, wind, and water.
