Abstract
This comined analysis of the ndhF and trnL-F genes provides support for recognizing Napoleonaeaceae and Scytopetalaceae as closely related but separate families from the Lecythidaceae. The Lecythidaceae are considered as three subfamilies: the Foetidioideae, Planchonioideae, and Lecythidoideae but the authors suggest that this classification is still open to change pending further study. An arguement for recognizing these three subfamilies as separate families is that there are no anatomical, cytological, or morphological synapomorphies uniting them in one family while, in contrast, there is at least one synapomorphy for each of the three lineages if they are treated as separate families. The New World genera Bertholletia, Corythophora, Couratari, Couroupita, Grias, and Gustavia are monophyletic as currently circumscribed and Allantoma and Cariniana would be monophylletic if the actinomorphic-flowered species of Cariniana were transferred to Allantoma. Eschweilera and Lecythis do not appear to be monophyletic but there is so little resolution among the zygomorphic-flowered species that relationships of the clades representing these two genera are not yet understood.
