Fucus barbatus Goodenough & Woodward, 1797: 103, 128, nom. illeg. (type locality: Devon, England).—Turner, 1811–1819: 124–125, pl. 250 ([var.] g).
Abrotanifolia barbata Stackhouse, 1809: 81.
Cystoseira barbata (Stackhouse) C. Agardh, 1820a: 57.—Misra, 1967: 233 (with query, but without author).— Ismail, Usmani, & Kalhoro, 1992: 145.
INDIAN OCEAN DISTRIBUTION: India, Pakistan, Sri Lanka.
Note: Roberts (1968: 257–258) gave reasons for considering Fucus barbatus Goodenough & Woodward a new species rather than a redescription of F. barbatus Linnaeus (1753: 1161; type locality: "Oceano''), even though she thought that the two names apply to the same species. When F. barbatus Goodenough & Woodward is interpreted as a later homonym, it is not priorable, and Abrotanifolia barbata Stackhouse, intended to be a new combination, is treated as a nomen novum in accordance with Art. 58.3.
