''Saccorhiza polyschides'', common name Furbellow, is a large brown algae of the lower shore and is the largest seaweed found in Europe.〔(Furbellows (''Saccorhiza polyschides'') ) The Sea Shore, accessed 21 September 2011.〕 ==Description==
''S polyschides'' is a large and bulky seaweed growing to 2-2.5 metres long. The holdfast is a large, hollow, knobbly structure. The stipe is long, tough, leathery and rigid and is several centimetres wide. Near the base the margin forms several broad, wavy frills. These ruffles tend to dissipate wave energy and lessen the likelihood that it will be torn from the rock. The frond is digitate with about eight large flat lobes and may be massive. The lack of a midrib distinguishes it from ''Alaria esculenta''.〔Newton, N. (1931). ''A Handbook of the British Seaweeds.'' British Museum, London.〕〔Dickinson, C. I. (1963). ''British Seaweeds.'' The Kew Series, Eyre & Spottiswoods.〕 It is an extremely fast growing species, growing annually from the base and becoming fully extended over the course of a few months.〔Barrett, J. H. and C. M. Yonge, 1958. ''Collins Pocket Guide to the Sea Shore.'' P. 225. Collins, London〕
