Description
Size: Height up to 60 cm or more.

Plants attached to the substratum by means of a basal disc-shaped holdfast. Main axis short, giving rise to several erect branches, with compressed stem, 3 mm broad in the lower portion and 2 mm above. Secondary branches separated by 2-3 cm interval, being 8-12 cm long, with the axes compressed below and cylindrical above; bearing 4-5 cm long branchlets. Leaves of the lower portion of the plants 5-6 cm long, alternate, linear margins entire, apices acuminate, midrib distinct, cryptostomata few, scattered on either sides of the midrib. Leaves of the lower portion 2.5-3 cm long, cylindrical filiform, midrib indistinct or absent, cryptostomata arranged along the margins. Leaves associated with receptacles, slender and capillary. Vesicles varying in size, being small to very minute, elliptical with pointed apex, stalked. Stalk of the vesicles flat, 5-10 mm or more in length. Sometimes vesicles occur on the tips of the leaves.

Receptacles in slightly racemose or cymose clusters, three or more together at the base of a leaf, oblong or linear, furcated, slightly flattened, more or less dentate especially at the apex. Antheridial and oogonial conceptacles present in the same receptacle.
