Venezuelan Ruellia (Acanthaceae): A Monograph. Mem (119) KITCHEN A New Species of EncephalartosThe Acanthaceae are among the 10 or so most taxonomically diverse families of flowering plants. Taxonomically, northern regions of the Neotropics including Mexico and much of Central America have been studied to a greater degree than have more southerly regions of the Neotropics including most of South America. In particular, the Acanthaceae biotas of Venezuela and Colombia are believed to be particularly rich as well as home to numerous endemics.
