Eisenia arborea, or the southern sea palm (not to be confused with the sea palm), is a species of kelp found in the inter-tidal zones of the Eastern Pacific from Vancouver Island, Canada south to Isla Magdalena, Mexico.[1] It is an edible seaweed, a source of nutrients for grazing marine invertebrates and a source of alginic acid, a food thickener. The alga has a large, thick stipe above its holdfast with two branches terminating in multiple blades. E. arborea is studied mainly because of the morphological variations in its blades due to inter-tidal forces.[2]

Phlorofucofuroeckol-B, a phlorotannin can be isolated from E. arborea.[3]
