In this study, we investigated the effect of geographical variations on Sargassum thunbergiimorphology to make a taxonomic reconsideration about infraspecific taxa in this species. Inorder to examine the morphological characteristics of S. thunbergii, total 27 matured and morphologicallyintact thalli were collected from the east, west and south coast in spring 2011. Interestingly,it was observed that the species populations on the west coast were characterized by short, thinand coarse thallus, and soft texture. However, the populations on the east coast showed thickerthallus, larger leaf and vesicle, and tougher texture. Thallus height of S. thunbergii was found tobe similar at both east and west coast. Further, the height of the thallus and lateral branch of thespecies populations residing south coast were highest whereas the size of leaf and vesicle are shortest,in comparison with east and west coast species. Although morphological characteristics of thenorth east coast populations corresponded to the original description of S. thunbergii f. latifolium,we could not find exact morphological features and diagnostic characters to distinguish form in S.
thunbergii. These results indicated that it is not the optimal characteristics to identify infraspecificform in this species. In contrast, morphological variations may signify the adaptation of thisspecies to local environmental factors. Thus, we recommend that intraspecific morphologicalvariation of S. thunbergii should be carefully used to identify infraspecific taxa.
