Ochrophytes - Definition, Glossary, Details - Oilgae
They include two groups of multicellular algae, the brown algae (Phaeophyceae) and some members of the yellow-brown algae (Xanthophyceae). Ochrophytes are the clade of photosynthetic heterokonts. Heterokonts are a well-supported clade of protists distinguished in most members by, among other features, a shorter posterior flagellum and a longer anterior flagellum with numerous side bristles (mastigonemes).
