In the past decade, molecular phylogenetic studies have contributed substantially for an improved circumscription of clades at all taxonomic levels, especially at the generic and tribal levels. For instance, a molecular phylogeny of Tribe Bignonieae reconstructed a polyphyletic Arrabidaea DC., and proposed a new circumscription for members of the ?Arrabidaea & Allies? clade. Within this new classification, most species previously included in Arrabidaea were distributed among four genera: Cuspidaria DC. (19 spp.), Fridericia Mart. emend. L.G. Lohmann (67 spp.), Tanaecium Sw. emend. L.G. Lohmann (17 spp.), and Xylophragma Sprague (7 spp.). The taxonomy of Fridericia, the genus that received most species of Arrabidaea, remains complicated due to the high morphological variability and broad distribution of its species. Here, we used molecular data and a broad sampling of taxa within the ?Arrabidaea & Allies? clade to reconstruct the phylogeny of Fridericia. We then studied the morphology of all species of Fridericia and identified morphological synapomorphies that characterize major clades that represent meaningful units for future taxonomic studies. Most genera included in the ?Arrabidaea & Allies? clade were retrieved as monophyletic; however, two species of Fridericia were reconstructed within Cuspidaria, while three species of Fridericia were placed within Tanaecium. The molecular phylogenetic placements received additional support from morphology, and the necessary taxonomic changes are here proposed. We combined three species of Fridericia in Tanaecium (i.e., T. dichotomum (Jacq.) Kaehler, & L.G. Lohmann, T. paradoxum (Sandwith) Kaehler & L.G. Lohmann, and T. parviflorum (Mart. ex DC.) Kaehler & L.G. Lohmann), two species in Xylophragma (i.e., X. claussenii (A. DC.) Kaehler & L.G. Lohmann, and X. corchoroides (Cham.) Kaehler & L.G. Lohmann), two species in Cuspidaria (i.e., C. bracteolata (DC.) Kaehler & L.G. Lohmann, and C. monophylla (A.H. Gentry) Kaehler & L.G. Lohmann), and one species of Adenocalymma in Fridericia (i.e., F. trichoclada (DC.) Kaehler & L.G. Lohmann). We also synonymize Fridericia whitei (Rusby) L.G. Lohmann into Cuspidaria pulchra (Cham.) L.G. Lohmann. We present a key for the seven main clades identified within the genus, as well as a detailed morphological description for Fridericia and its major lineages.} }
