Wolffia and duckweed (Lemna) are now considered to be closely allied to the
infamous Amorphophallus titanum (aroid) so it will necessitate eventually
that their family Lemnaceae be merged into Araceae or that a new family be
created to accommodate them and splitting Araceae. not that this is rainbow
