Thalli erect, yellowish brown to dark brown in colour, attached by coarse branched holdfasts to rocky substrate, forming thick, huge colonies. Axes terete, muricate at the basal portion. Leaves are 6 to 12 mm long, consisting of a stalk, small vesicles and an expanded distal marginal blade outlined by coarse teeth; leaves triangular in outline or irregularly rounded in surface view; 3.5 to 9.0 mm across, sometimes deeply cut on one side, the cut often reaching the vesicle. Receptacular clusters 3 to 10 mm long, generally shorter and attached to the stalk of the leaves at 1/4 the distance from the main axis. This species is easily distinguished by its lax branched thalli, numerous branches, and small turbinate leaves with a length of about 1 cm or less. Thalli up to 1.5 m in height (Ref. 80758).
Used for human consumption, as fertilizer and insect repellant; contains minerals (Ca, K, Mg, Na, Cu, Fe, Zn); source of algin, tannins and phenols (Ref. 80758).
