| dc.description.abstract | Phylogenetic analyses of molecular and morphological data have shown the genus <i>Banisteriopsis</i> to be polyphyletic and the genus <i>Diplopterys</i> to be nested within <i>Banisteriopsis</i> subg. <i>Pleiopterys</i>, which is not in the clade that contains the type of the name <i>Banisteriopsis</i>. Therefore, it is necessary to take up the name <i>Diplopterys</i> for the small genus formerly called that plus subg. <i>Pleiopterys</i> of <i>Banisteriopsis</i>. Adescription of the amplified genus <i>Diplopterys</i> is provided, two new species are described (<i>D. bahianaand</i> and <i>D. carvalhoi</i>), and the following new combinations in <i>Diplopterysare</i> proposed, with all combinations by W. R. Anderson and C. Cav. Davis: <i>D. amplectens</i>, <i>D. cachimbensis</i>, <i>D. caduciflora</i>, <i>D. cristata</i>,<i>D. erianthera</i>, <i>D. heterostyla</i>, <i>D. hypericifolia</i>, <i>D. krukoffii</i>, <i>D. leiocarpa</i>, <i>D. longialata</i>, <i>D. lucida</i>, <i>D. lutea</i>, <i>D. nigrescens</i>, <i>D. nutans</i>, <i>D. patula</i>, <i>D. peruviana</i>, <i>D. platyptera</i>, <i>D. populifolia</i>, <i>D. pubipetala</i>, <i>D. rondoniensis</i>, <i>D. schunkei</i>, <i>D. sepium</i>, <i>D. valvata</i>, <i>D. virgultosa</i>, and <i>D. woytkowskii</i>. Illustrations are provided for <i>D. bahiana</i>, <i>D. cabrerana</i>, <i>D. carvalhoi</i>, <i>D. pauciflora</i>, <i>D. pubipetala</i>, and <i>D. valvata</i>. | en |
