DEEP-WATER MACROALGAE FROM THE CANARY-ISLANDS - NEW RECORDS AND BIOGEOGRAPHICAL RELATIONSHIPS

Due to the geographical location and paleobiogeography of the Canary I slands, the seaweed flora contains macroalgae with different distribut ional patterns. In this contribution, the biogeographical relations of several new records of deep-water macroalgae recently collected aroun d the Canarian archipelago are discussed. These are Bryopsidella negle cta (Berthold) Rietema, Discosporangium mesarthrocarpum (Meneghini) Ha uck, Hincksia onslowensis (Amsler et Kapraun) P. C. Silva, Syringoderm a flozidana Henry, Peyssonnelia harveyana J. Agardh, Cryptonemia semin ervis (C. Agardh) J. Agardh, Botryocladia wynnei Ballantine, Gloioclad ia blomquistii (Searles) R. E. Norris, Halichrysis peltata (W. R. Tayl or) P. Huve et H. Huve, Leptofauchea brasiliensis Joly, and Sarcodioth eca divaricata W. R. Taylor. These new records, especially those in th e Florideophyceae, support the strong affinity of the Canary Islands s eaweed flora with the warm-temperate Mediterranean-Atlantic region. So me species are recorded for the first time from the east coast of the Atlantic Ocean, enhancing the biogeographic relations of the Canarian marine flora with that of the western Atlantic regions.
