 In 1941 another American botanist, Orator F. Cook, moved Beccari's C. anomala to a new genus, Oothrinax. This generated a fourth combination, O. anomala. Since Descourtilz's description pre-dates that of Beccari, Zombia antillarum (which is based on Descourtilz's description) has priority over Oothrinax anomala. In addition, Cook's name is invalid, since it was apparently never formally described.
