Description: Thallus of this brown kelp has a branched, rhizomatous holdfast, with numerous stipes arising from the extensive holdfast structure. A long, narrow blade, less than 5 cm (2 in) wide and up to 50 cm (20 in) long, extends from each stipe. Coilodesme fucicola and Porphyra gardneri are common epiphytes along old blade margins. Habitat: This perennial kelp grows on rock in the low intertidal of semi-exposed to exposed habitats. Similar taxa: Lessoniopsis also has narrow blades but a different holdfast.
