As now circumscribed, sect. Daubentonia comprises only New World species, although Sesbania punicea is an escaped ornamental in Africa and elsewhere ( Lewis 1988). Daubentonia now includes sect. Daubentoniopsis, which has long, linear, but torulose pods that are quite different from the short, quadratebodied, often-winged pods of the traditionally circumscribed Daubentonia. Given the distribution of Daubentoniopsis is centered in Jalisco and Michoacan, Mexico ( McVaugh 1987), geographic proximity predicts the degree of phylogenetic relatedness more than similarities in pod morphology, at least for species of Sesbania . McVaugh (1987; pp. 697–698) details the complicated nomenclature of the sole species of Daubentoniopsis, Sesbania cavanillesii S. Watson (5 S. longifolia DC. ).
