Note: Padina commersonii Bory de Saint-Vincent (1828 [1826–1829]: 144), a name that traditionally has been applied to the present species, is an illegitimate substitute for P. tenuis (C. Agardh) Bory de Saint-Vincent (1827b: 590), whose basionym, Zonaria pavonia var. tenuis C. Agardh (1824: 264; type locality: Mariana Islands), has been shown by Womersley & Bailey (1970: 293) and Papenfuss (1977: 277) to be referable to Lobophora variegata (Lamouroux) Womersley ex Oliveira (q.v.). The material that Bory de Saint-Vincent had in hand (a Commerson collection from Mauritius) was incorporated in a new species, P. boryana, by Thivy. In an alternative treatment, Womersley & Bailey (1970: 292–293) interpreted P. tenuis as a new species typified with the Commerson collection from Mauritius. Vaughaniella rupicola Børgesen is included as a possible synonym of P. boryana on the authority of Børgesen (1951: 11–14, fig. 4), who pursued a suggestion made by Cribb in correspondence (later published: Cribb, 1951).
