Laminaria sinclairii (Harvey ex J.D.Hooker & Harvey) Farlow, Anderson & Eaton, 1878
This dark brown, perennial kelp grows from a creeping, branching rhizome which sends up thalli at intervals. The thalli are ribbon-like and grow to a length of about 1 m (3 ft) and width of 3 cm with a smooth surface and entire edges. They grow on short, cylindrical stipes some 10 cm long and 5 mm wide containing many mucilage ducts.
