Morphologie
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). Thrives mostly on sandy coralline bottoms on reef portions which are not exposed to excessive water turbulence; usually in shallow lagoons or tidepools in subtidal habitats protected from strong wave action (Ref. 80758).
