Color: Yellow brown

Thalli about 50-80 cm in height, slender with irregular branches. Main axes cylindrical about 3-5 mm in height, stout, giving rise to several primary branches, attaching by means of scutate discoid holdfasts. Primary branches cylindrical, smooth, slender, about 1-1.5 mm diameter, giving off secondary branches, much more slender, beset with branchlets. Basal leaves thickened, 3 cm long, 3-4 mm broad, with conspicuous percurrent midribs. Leaves of the branches linear-lanceolate, 4-5 cm long, 1.5-2 broad, midrib percurrent, shallowly dentate at the margins, cyptostomata very small, scattered on both sides of the midrib. Leaves of the branchlets somewhat shorter and narrower, 3-4 mm long, 1-1.5 mm broad or much narrower, with irregular short teeth at the margins.

Vesicles nearly spherical, 2-3 mm diameter, rounded at apices, pedicillate. Receptacles cylindrical, acute at the apices usually forked 2-3 times, characteristically zygocarpic, the upper portion of the receptacles bearing leaflets or minute vesicles, solitary or 2-3 arranged in short receme.
