Multiple radial branches at base giving rise to several long primary branches. Branchlets (ramuli) are thin, short and can be cylindrical (terete), simple, branched or leaf-like in shape. Lower primary branches are denuded with short spines (muricate). Single or chain-like floats (vesicles) occur within branchlets and are either egg (ovoid) or spindle (fusiform) in shape. Medium brown. Up to 60 cm long (thallus).
The tropical form of this species is more "leafy" than the southern form which is usually only leafy at the base.
