Recent phylogenomic analyses have revealed that Albizia carbonaria Britton is not a member of Albizia section Arthrosamanea, but rather the sister-group of Pseudosamanea Harms. This paper discusses its morphological similarities to Pseudosamanea and presents the reasons and evidence for placing Albizia carbonaria in the genus Pseudosamanea.
Recent phylogenomic analyses placed Albizia carbonaria Britton as the sister-group of the two currently known species of Pseudosamanea Harms, clearly outside Albizia section Arthrosamanea (Britton & Rose) Barneby & J.W. Grimes where it has until now been included. Its morphological similarities to Pseudosamanea are discussed, including characteristics of the polyad, and it is concluded that the species is compatible with the generic description of that genus except for its much more finely divided leaves with smaller leaflets, and its smaller flowers and fruits. Since these are merely quantitative differences, the species can readily be accommodated in Pseudosamanea. The new combination Pseudosamanea carbonaria (Britton) E.J.M. Koenen is made, and a diagnosis distinguishing it from the other two species of Pseudosamanea is presented.
