SARGASSUM AND THE SARGASSO SEA.

The article discusses a study which investigated the species of Sargassum found along the coasts of the Danish West Indies with remarks upon the floating forms of the Sargasso Sea. The Sargassum species include Sargassum vulgare, found on both exposed and sheltered places. The second part of the study deals with the floating Sargassum found in the Sargasso Sea, which are referred to as Sargassum natans and a coarser form which the author called Sargassum hystrix. The biology, affinities and origin of the floating pelagic gulfweed forms are also discussed.
