Resumo
Augusta has traditionally been placed in the tribe Rondeletieae, subfamily
Cinchonoideae. However, recent molecular phylogenies positioned it near to Wendlandia
(Ixoroideae), but locate A. longifolia near to the clade Ixoroidinae II. The study of A. longifolia
afforded two coumarins, five flavonoids, three triterpenoids and one benzoic acid derivative. These
metabolites reinforce the separation of Augusta as a monospecific genus, and Lindenia as a genus
of three species, closely related to Wendlandia.
