'''''Cordaicarpus''''' is a form genus named by ''Geinitz'' (1862) and redefined by ''Seward'' (1917) to avoid confusion with another genus and to establish that the genus refers only seeds. ''Seward'' defined the differences between ''Cordaicarpus'' and ''Samaropsis''.<ref>{{citation |url=http://www.sbpbrasil.org/revista/edicoes/12_1/souza.pdf |title=The Genus ''Cordaicarpus'' Geinitz In The Lower Permian Of The Paraná Basin, Rio Grande Do Sul, Brazil |author=Juliane Marques De Souza and Roberto Iannuzzi |year=2009 |journal=Revista Brasileira de Paleontologia |volume=12 |issue=1}}</ref>
