Abstract

The myrrh genus, Commiphora (Burseraceae), is the most species rich in the frankincense and myrrh family, Burseraceae, and is represented by several interesting distributions, globally. The taxonomic history at both species- and infrageneric levels has been problematic and we seek to evaluate existing classifications and test for the phylogenetic conservatism of traits traditionally used in infrageneric circumscription and the identification of species boundaries. Among species of Commiphora from Madagascar ? all of which are endemic ? previous studies indicate that the genus has radiated to the island twice. We seek to reconstruct species-level relationships in Commiphora using a more exhaustive taxon sampling, emphasizing priorities established in previous studies. We have achieved a nearly comprehensive sampling of species from Madagascar and employ phylogenetic reconstruction methods using five molecular markers (nrETS, nrITS, psbA?trnH, ndhF?rpl32, and trnD?trnT). Results from this expanded sampling support a monophyletic Commiphora and indicate strong support for seven clades that we refer to as the ?Lasiodisca?, ?Granuliferous?, ?Saxicola?, ?Gariepensis?, ?Spinescent?, ?Arafy?, and ?Rhynchocarpa? clades. Further, species of Commiphora appear to have dispersed to Madagascar from continental Africa no fewer than four times. We describe the morphological and geographic affinities of each of these six clades and identify priorities for future study in the group.
