Frond flat, membranous, leaf-like with distinct midrib and parallel veins. Stem cylindrical, simple or branched, being the thickened and denuded midrib of promordial leaf-like structures, very rigid hard when dry. Leaves simple or pinnately lobed, linear oblong membranous, lamina in older plants decayed and midrib serving as a stripe. Lamina 8-15 cm or more long, 10-25 cm broad, obtuse at base, emarginate and rounded at apices, slightly undulate serrated throughout. Younger leaves starting from the midrib of older lamina. Veins patent with proliferations. Proliferations repeatedly arising from both surfaces of midrib. Teeth along margins of lamina, spinose with subulate and recurved ramuli; similar processes arising from veins and midrib also. Fructifications in secondary adventitious branchlets.

Stichidia elongated, ovate or oblong, apex rounded, shortly stipitate, containing double rows of tetrasporangia. Tetrasporangia 100 µ long, 70 µ broad. Androphore spherical, 120 µ in diameter. Procarp obovate, urn-shaped 60 µ broad, 70 µ long. Cystocarp solitary. Substance very crisp and rigid.

Inhabitant of deeper waters, well protected from the direct action of waves or sunlight.
