What is the leaf for a brown algae (kelp) called? Macrocystis pyrifera, commonly known as giant kelp or giant bladder kelp, is a species of kelp (large brown algae), and one of four species in the genus Macrocystis. ligulata in partSimilar species: Desmarestia ligulata has narrower blades with >2 orders of side branching giving it a bushier appearance. Phylum: Heterokontophyta It is the largest seaweed. Abundant, on rocks in shallower areas of kelp forest, usually most abundant on shallower margins of forest. Family: Laminariaceae. Geogr. Spesies: Macrocystis pyrifera. Common but patchy & sporadic; on rocks, particularly in areas that are frequently or recently disturbed (e.g. Phylum Phaeophyta (brown algae) - The color of brown algae results from the dominance of the xanthophyll pigment, fucoxanthin, over the Chlorophyll a and c and other pigments. In general, this kelp is reported to be reproductive all year round. Blades develop at irregular intervals along the stipe. Range: British Columbia to north Channel IslandsSynonyms: Geogr. Moderately common, on rocks; low intertidal and shallow subtidal.
