abstract = {Orphanodendron is a taxonomically and geographically isolated South American genus of two species. When first described by Barneby and Grimes in 1990, the genus was placed in Leguminosae subfamily Caesalpinioideae, but that placement was doubted and the name Orphanodendron (Gr. orphanos, orphan + dendron, tree) was chosen to reflect the uncertain subfamilial relationship of the genus. In this study, nucleotide sequence data from five Orphanodendron specimens were added to 662 other, previously sampled, Leguminosae taxa representing all three currently recognized subfamilies (Caesalpinioideae, Mimosoideae and Papilionoideae) in a matK maximum parsimony analysis that resolved Orphanodendron as a member of the genistoid s.l. clade of subfamily Papilionoideae. Two additional Bayesian phylogenetic analyses with reduced taxon sampling of plastid (matK combined with trnL-F) and nuclear (ITS) loci strongly support the monophyly of Orphanodendron and unambiguously establish Orphanodendron as a member of the genistoid sensu lato clade. Although our plastid phylogenetic analysis finds relatively low support (0.6 posterior probability) for a sister-group relationship with the African genus Camoensia, the nuclear-encoded ITS resolves Orphanodendron as sister to the Bowdichia clade with strong support and Camoensia as sister to other core genistoids. The phylogenetic resolution of Orphanodendron as a member of the genistoid s.l. legumes based on nuclear and plastid sequences will undoubtedly advance future evolutionary investigations of this Colombian endemic tropical tree genus. }
