The Duckweed Family [Lemnaceae] has been subsumed into this, the Arum Family. The Lemnaceae Family was comprised of the Genera: Lemna, Spirodels and Wolffia, all of which are now contained within the Arum Family. The Arum family is typified by flowers with a single large spathe surrounding a central pencil-thin spadix. The upper majority of the upper part of the spadix contains the male flowers; the female flowers of all Arum plants are on the lower (usually hidden) part of the spadix. They are mostly very poisonous. Text on Family goes here
