Fucus spinosus Linnaeus, Mantissa Plantarum Altera: 313. 1771, nom. illeg.

"Habitat ad Cap. b. spei." RCN: 8356.

Replaced synonym: Fucus denticulatus Burm. f. (1768) .

Type not designated.

Current name: Eucheuma denticulatum (Burm. f.) Collins & Herv. ( Solieriaceae).

Note: A superfluous name for F. denticulatus Burm. f. (1768) and also a later homonym of F. spinosus Gmelin (1768) . Although Doty (in Abbott, Taxon. Econ. Seaweeds 2: 179 1988) treated 1274.104 (LINN) as the type, this shows no connection with F. denticulatus and is not original material for that name.
