Proximal pistillate scales with apex acute or mucronate. Perigynia rigidly spreading, veinless on faces but with 2 strong marginal veins, stipitate, transversely wrinkled, very broadly obovate, compressed-trigonous in cross section, base cuneate, apex rounded, abruptly beaked, glabrous; beak bent, to 0.2 mm, orifice entire or emarginate.
