Gandolfo, M. A., M. C. Dibbern, and E. J. Romero. 1988. Akania patagonica n. sp. and additional material on A. americama Romero & Hickey (Akaniaceae) from Paleocene sediments of Patagonia. Bulletin of the Torrey Botanical Club 115 (2): 83-88130.

Abstract: New specimens of Akania americana Romero & Hickey and a new species in the same genus, Akania patagonica n. sp. are described. Comparisons are made with the only living species, A. hilli, endemic to east Australia. All the fossils are found in the La Huitrera Formation (Paleocene) Chubut Provence, Argentina. The fossils support the idea that the Akaniaceae were diversified and widespread in the southern hemisphere during the Paleogene, and that close relationships existed between South America and Australia at that time.

Resumen: Se describen nuevos ejemplares de Akania americana Romero & Hickey y una nueva especie del mismo género, Akania patagonica n. sp. Se compara la única especie viviente, Akania hilli, endémica de Australia Oriental. Todos los fósiles pertenecen a la formación La Huitrera (Paleoceno), Provincia del Chubut, Argentina. Los fósiles indican que las Akaniaceae estaban diversificadas y difundidas durante el Paleoceno, y que en ese momento existieron relaciones estrechas entre Australia y América del Sur.
