Special Features and Information
Etymology
The name Bidens is derived from the Latin bi, two, and dens, teeth in reference to the pappus awns or collective bristles on the achenes (fruit, seeds).
The species epithet menziesii refers to Archilbald Menzies (1754-1842) a Scottish surgeon and naturalist, and the first to taxonomically identify the species. [1]
