Leal, A. fanshawei (Maguire) Harling, A. glandulosa (Gleason) Harling, A. heteranthera Harling, A. latifrons (Drude) Harling, A. schizotepala Harling, A. xiphophylla Harling, Cyclanthus bipartitus Poit. ex A. Rich., Evodianthus funifer (Poit.) Lindm., Ludovia lancifolia Brongn. and Thoracocarpus bissectus (Vell.) Harling. An identification key, descriptions and illustrations of species are presented. Additional information on the geographic distribution, habitat, and flowering and fruiting periods are also provided.
