Basionym: Schistogyne boliviensis Schlechter (1914: 442) , [ non Oxypetalum boliviense Schlechter (1906: 602) ]. Type: BOLIVIA . “Windend im Gebüsch an der Waldgrenze bei Tres Cruces”, February 1911 , T. Herzog 1630 ( lectotype (here designated) L!, duplicate F!]. Note :—The lectotype is designated here because the holotype at B was destroyed. Etymology :—The 7-lobed appendage of the gynostegium was used to recognise Schistogyne ; however, this is the only Bolivian species that presents this characteristic, which is why we chose this epithet.
