Nomenclatural notes
"This species was described by Ducluzeau (1805: 61) from Séte, Hérault (France). The name is illegitimate because it is a later homonym of C. nodulosum De Candolle (see Lamarck & De Candolle, 1805: 45). It was reported by Cecere et al. (1996: 201) from the Cheradi Islands (Taranto, Italy) and by Conde et al. (1996: 11) from the coast of Andalusia (Spain). It should be noted that in the aforementioned papers the species is erroneously credited to (Lightfoot) Ducluzeau. For the nomenclatural history of the species, see Silva et al. (1996: 402)." (Cormaci & al. 2023: 232). - (15 November 2023) - M.D. Guiry
The name C. nodulosum Ducluzeau is a later homonym (published 27 December 1805) of C. nodulosum De Candolle (in Lamarck & De Candolle, 1805: 45, published 17 September 1805 (Silva et al. 1996: 402). - (27 August 2009) - G.M. Guiry
Taxonomic note
According to Silva et al., Ducluzeau's account of C. nodulosum makes it clear that he was describing a new species and nowhere did he cite Lightfoot, either directly or indirectly. They also note that he explicitly excluded two species from his concept of C. nodulosum, namely, Conferva rubra Hudson and C. nodulosa Hudson 1778, nom. illeg. - (27 August 2009) - G.M. Guiry
