− | | description =Sargassum muticum is a large brown seaweed of the Division Phaeophyta. It grows attached to rocks by a perennial holdfast up to 5 cm in diameter. From this holdfast the main axis grows to a maximum of 5 cm high. The leaf-like laminae and primary lateral branches grow from this stipe. In warm waters it can grow to 12 m long, however in British waters it grows to no more than 4 m long. The holdfast gives rise to a single main axis with secondary and tertiary branches which are shed annually. Numerous small 2-6 mm stalked air vesicules provide buoyancy. The reproductive receptacles are also stalked and develop in the axils of leafy laminae. It is self fertile. | + | | description = |
