Thalli large, dark brown to yellowish brown, attached to rocks by a coarse branching holdfast; stem short cylindrical. Primary branches terete, bearing irregularly alternate secondary branches with numerous simple and Y-shaped proliferations. Mature thalli with fewer and smaller oblanceolate leaves, 7 to 15 mm long and 1.5 to 4 mm wide, with coarsely dentate or serrated margins; midrib prominent up to near the apex. Cryptostomata scattered on the surface of leaves. Stalked vesicles ovate or spherical, numerous; vesicles attached to the secondary, tertiary and terminal branches either singly or in clusters, 1.0 to 2.5 mm in diameter, bearing few cryptostomata and/or teeth-like structures. Plant dioecious. Male receptacles racemose-paniculate, receptacular branches terete, warty. Female receptacles small, cymose; receptacular branches short, dense, compressed, simple or forked with teeth or spines at margins. Thalli up to 40 cm in height (Ref. 80758).
Used as fertilizer, as human food, fodder and medicine; contains auxin-like substance; controls heavy metal (Pb, Cd) pollution; also a source of alginate; may form dense stands and is therefore considered as a good biomass source for biogas production; used as soil fertilizer (Ref. 80758). Usually thrives in inner reef areas on coarse, sandy coralline substrate, not exposed to strong water turbulence (Ref. 80758).
