Sargassum C.Agardh, 1820 [WoRMS]; Marine
ON February 17, 1973, some thirty scattered plants of the brown algal genus Sargassum were found attached on a sheltered shore in Hampshire. This is the only record for attached plants of a species of Sargassum in Britain. The specimens were well grown, attaining a length of up to 1 m (Fig. 1), and showed the characteristic morphology of this genus with monopodial branching, air-bladders and leafy laterals. We are confident that these plants constitute a recent introduction as the area has been under surveillance since 1967, being one of the localities for a possibly-introduced Grateloupia sp. (red alga).
