The genus "Oceanopapaver", previously of uncertain placement, has recently been synonymized under "Corchorus". The name was established by Guillaumin in 1932 for the single species "Oceanopapaver neocaledonicum" Guillaumin from New Caledonia. The genus has been classified in a number of different families including Capparaceae, Cistaceae, Papaveraceae, and Tiliaceae. The putative family name "Oceanopapaveraceae" has occasionally appeared in print and on the web but is a nomen nudum and has never been validly published nor recognised by any system of plant taxonomy.
