Most of the known species diversity in the parasitic plant family Orobanchaceae occurs in temperate regions. However, diversity in the well-supported clade of tropical Orobanchaceae remains largely unexplored. With the exception of Buchnera <\/em>(with 100 species), most genera of the tropical clade consist of few poorly characterized and rarely collected species. Although tribe-level classification systems include such poorly known genera, few thorough phylogenetic analyses exist to test these interpretations. In this study, we have expanded phylogenetic sampling of tropical species and genera in over previous studies through field collection of species from the paleotropics and neotropics. For the first time, the genera Buttonia, Cycniopis, Ghikea, Gerardiina, Magdalenaea, Micrargeriella, Nothochilus, Physocalyx, Pseudosopubia<\/em> and Velosiella<\/em> are included in systematic analysis of the tropical clade. Further, species sampling of genera Buchnera, Cycnium, Melasma, Sopubia, <\/em>and Striga,<\/em> has been greatly expanded.DNA sequences of the following loci were obtained from circa <\/em>150 ingroup and outgroup accessions of more than 100 species: the nuclear Internal Transcribed Spacer (ITS) and chloroplast loci matk, rbcL, rpl16, <\/em>and rps2<\/em>. Phylogenetic analysis was used to explore 1) monophyly and relationships among major genera and 2) proposed tribe-level taxonomies. Additionally, whole plastomes were used to investigate patterns of plastome evolution in clades including holoparasitic members.<\/p>\n\n\n\n Speaker: <\/strong>Dr. Christopher P.
