A phylogeny of Uniolinae with a new genus, Eragrostiola and combination, E. spicata (Poaceae, Chloridoideae, Eragrostideae, Uniolinae)
Abstract
We present a molecular DNA phylogeny of Uniola utilizing three plastid ( rps16-trnK spacer, rps16 intron, rpl32-trnL spacer) and the nuclear ribosomal internal transcribed spacer (ITS) regions investigating 87 species of tribe Eragrostideae, including an increase in the sampling of species known to occur within Uniola . We describe a new genus, Eragrostiola , and make a new combination, Eragrostiola spicata , for a species that had been placed in Eragrostis for 134 years. Uniola and Eragrostiola include six species all native to the western hemisphere, share a common ancestor with the Fingerhuthia ( Entoplocamia + Tetrachne ) clade of African origin.
