The 'Nidularioid Complex' is a group within the Bromelioideae usually characterized by inflorescences nested within water-impounding foliar rosettes. Currently, it comprises six genera: Canistrum, Canistropsis, Edmundoa, Neoregelia, Nidularium, and Wittrockia. While most of these genera occur in eastern Brazil, the distribution of Neoregelia is disjunct between the Atlantic Rainforest and Amazonia. Previous phylogenetic studies have not addressed the monophyly of and relationships among these genera; therefore, we undertook a phylogenetic study of the Nidularioid Complex with emphasis on the genus Neoregelia and its subgenera. A parsimony-based phylogenetic analysis with 101 morphological characters retrieved the Nidularioid Complex as non-monophyletic. Nidularium and Edmundoa were monophyletic. Neoregelia was recovered as non-monophyletic due to the inclusion within it of the Amazonian subgenus Hylaeaicum. These results highlight the need for revision of the generic classification of Bromelioideae, pending increased sampling of taxa and characters.
