“{{w|Aconitum}} has a number of common names, one of which is monkshood, so called because of the enlarged {{w|sepal}} that resembles a hood, under which the rest of the floral parts are hidden. Roots were used as poison bait for wolves, thus accounting for another popular name, wolfsbane. All aconitums have poisonous roots, leaves, and stems and warnings concerning their poisonous properties have been sounded since the late 1500s.”
