Fucus articulatus S. Gmelin, 1768: 77 (type locality: "Oceanus Indicus'').—C. Agardh, 1820a: 101.
INDIAN OCEAN DISTRIBUTION: "Oceanus Indicus''.
Note: S. Gmelin (l.c.) cited "T.II f.I.'', but the planned illustration was not published. There are no literature citations in the protologue. The description suggests that this species may be representative of Sargassum, but its status remains undeterminable in the absence of an authentic specimen.
