Small specimens, very stiff plants; double crested and dentate upper margin of the short, broad and fleshy leaves. Aerial vesicles absent. Plants attached to the substratum by means of a discoid holdfast. Axes of the plant rough, flattened, about 2-3 mm broad. Several branches arising together with similarly disposed branchlets, the latter 5-6 cm in length. Leaves petiolate, oblong-elliptical, margins dentate, teeth bifid, midrib confined to lower part, upper ends of the leaves double edged, cryptostomata few but conspicuous. Leaves of the lower portion larger, 2-2.5 cm long and 1-1.3 cm broad; of the upper portion 1.5-2 cm long and 8-10 mm broad. Vesicles borne on more or less inflated petiole, the former 4-5 mm long, ellipsoidal with pointed apex.

The material is fertile with spiny receptacles. Receptacles densely aggregated, forming branched racemose-cymose clusters in the axils of the leaves, surface of the receptacles warty.
