Description
Color: Yellow brown

Thalli reaching height of 70-90 cm, arising from depressed, scutate discoid holdfast. Main axes cylindrical, about 3-5 mm long, giving rise to several primary branches. The primary branches cylindrical, smooth, lower parts 1.5-2 mm diameter, tapering above. Secondary branches similar to primary ones in shape, alternately arranged, about 50-60 cm long, beset with branchlets. Branchlets short and slender, generally 5-7 cm long, 4-6 mm diameter with dense leaves, vesicles and receptacles. Basal leaves elongated, ellipsoidal or obovate, 2-3 cm long, 5-10 mm broad, apices obtuse, unequal and cuneate at the bases, dentate at the margins, usually outward margins more dentate than inward ones. Leaves on branchlets small, obovate, 10-15 mm long, 3—8 mm broad, midrib, often vanishing at the middle parts of the leaves, cyptostomata conspicuously prominent, scattered all over surface.

Vesicles borne on dilated petiole, spherical, 3-5 mm diameter with a few cryptostomata and flattened pedicles, 2-4 mm long, usually with ear-like wings on both sides of the vesicles. Monoecious. Receptacles racemosely branched, triquetral, serrate , shortly pedicellate, flattened, forked and dentate, about 2-3 mm long, in the axils of the leaves, arranged in racemes.
