Abstract
The legume tribe Amorpheae comprises eight genera and 240 species with variable floral form. In this study, we inferred a phylogeny for Amorpheae using DNA sequence data from the plastid trnK intron, including matK, and the nuclear ribosomal ITS1, 5.8S, and ITS2. Our data resulted in a well-resolved phylogeny in which the tribe is divided into the daleoids (Dalea, Marina, and Psorothamnus), characterized by generally papilionaceous corollas, and the amorphoids (Amorpha, Apoplanesia, Errazurizia, Eysenhardtia, and Parryella), characterized by non-papilionaceous flowers. We found evidence for the paraphyly of Psorothamnus and for the monophyly of Dalea once D. filiciformis is transferred to monophyletic Marina. Errazurizia rotundata is more closely related to Amorpha than to the other errazurizias, and Eysenhardtia is supported to be monophyletic. The monotypic Parryella and Apoplanesia are placed within the amorphoids. Among Papilionoideae, trnK/matK sequence data provide strong evidence for the monophyly of Amorpheae and place Amorpheae as sister to the recently discovered dalbergioid clade.
