--><p>Bahia dissecta is treated here in Amauriopsis; B. oppositifolia and B. woodhousei are treated in Picradeniopsis; B. nudicaulis is treated in Platyschkuhria. These departures from the treatment of Bahia in a broad sense by W. L. Ellison (1964) are consistent with findings by B. G. Baldwin et al. (2002).</p>
