Along a rocky shore. Abundant Nereocystis and Alaria fistulosa. In the eastern north Pacific, the genera Rhodoglossum and Iridaea are inadequately delineated. The name Iridaea cordata, almost certainly incorrect, serves as an umbrella epithet for species in this complex until detailed studies clarify its taxonomy and nomenclature.
