However, taxonomic revision of this genus and resurrection of Saccharina Stackhouse based on genetic studies resulted in transfer of most Laminaria species to Saccharina. At the Russian Pacific coasts Saccharina now includes 10 species, while only three species for sure represent Laminaria： L. longipes Bory de Saint-Vincent, L. solidungula J. Agardh, L. yezoensis Miyabe, their placement within Laminaria is supported by genetic data. All examined Far Eastern species of Saccharina are noticed to possess haptera in the form of rhizoids, whereas members of Laminaria have disk-like holdfasts （L. solidungula, L. yezoensis）, or creeping rhizomes （L. longipes）. Three unstudied genetically endemics from the Sea of Okhotsk： L. appressirhiza Petrov et Vozzhinskaya, L. inclinatorhiza Petrov et Vozzhinskaya, L. multiplicata Petrov et Suchovejeva, are still left within Laminaria, but they have rhizoids, so most probably belong to Saccharina. This morphological criterion is inapplicable to Atlantic Laminaria since the type species L. digitata （Hudson） Lamouroux has rhizoids.展开更多
