Misleading fruits: The non-monophyly of Pseudopiptadenia and Pityrocarpa supports generic re-circumscriptions and a new genus within mimosoid legumes.

ABSTRACT: Generic delimitation in Piptadenia and allies (mimosoid legumes) has been in a state of flux, particularly caused by over-reliance on fruit and seed morphology to segregate species out of Piptadenia into the genera Parapiptadenia, Pityrocarpa and Pseudopiptadenia. Although supporting their segregation from Piptadenia, previous phylogenetic analyses suggested that some of these segregated genera are not monophyletic. Here, we test the monophyly of Parapiptadenia, Pityrocarpa and Pseudopiptadenia with dense taxon sampling across these genera, including the type species of each genus. Our analysis recovers Parapitadenia as monophyletic, but places Pseudopiptadenia species in two distinct lineages, one of which includ
