Brown algae (Phaeophyceae) from Russian Far Eastern seas: re-evaluation of Laminaria multiplicata Petrov et Suchovejeva

Abstract

Eight unusual individuals of a laminariaceaen species were collected from the Sea of Okhotsk in 1974 and described as a new species, Laminaria multiplicata Petrov et Suchovejeva in 1976. Since that time no new information, including pictures and numerical data, has been provided, although the species was cited in floristic lists of the Sea of Okhotsk based on the first record in 1976. We investigated a type and 3 paratypes of L. multiplicata and strongly believe that they were wrongfully identified abnormal plants of L. gurjanovae A. Zinova. Therefore, the species L. multiplicata needs to be closed.
