Note: The synonymy was proposed by Johansen & Womersley (1986). Hariot (1902: 472) reported an alga from Madagascar under the name Corallina natalensis, which he attributed to Areschoug (1852: 574). In the cited publication, Areschoug stated that C. natalensis was a name applied in his herbarium to an alga previously distributed in his extra-European exsiccata (1850a: no. 23) as Jania rosea. The manuscript name C. natalensis Areschoug should not be confused with C. natalensis (Harvey) Kützing (1858: 38, pl. 79: figs. IIc–f), which is treated as a taxonomic synonym of Jania verrucosa Lamouroux (q.v.).
