SB23009Taxonomic study of Senna section Chamaefistula series Bacillares (Fabaceae) in the Atlantic Forest north of the São Francisco River, Brazil, and nomenclatural updates
A taxonomic study of Senna series Bacillares (Fabaceae) was conducted in the Atlantic Forest north of the São Francisco River in north-eastern Brazil, one of the global biodiversity hotspots. More than half of the species in this series are endemic to Brazil, and ~20% are represented in the study area, with Senna pluribracteata F.S.Souto & R.T.Queiroz being narrowly endemic. The typification of names in this work supports correct taxonomic interpretation, being important for the identification and distinguishing of taxa. (Photograph by R. T. Queiroz.)
