Fucus granulatus Linnaeus, Species Plantarum, ed. 2, 2: 1629. 1763.

"Habitat in Oceano Indico." RCN: 8284, 8325.

Lectotype (Roberts in J. Linn. Soc., Bot. 60: 264, pl. 5. 1968): Herb. Linn. No. 1274.11 (LINN) .

Current name: Cystoseira usneoides (L.) M. Roberts ( Cystoseiraceae).

Note: Although Roberts (in Bot. J. Linn. Soc., Bot. 60: 260. 1968) believed this to be a superfluous name for F. usneoides L. (1759), the protologues of the two names are far from identical, although the annotations to material in LINN suggest that Linnaeus regarded them as conspecific.
