Female glumes yellowish brown, ovate, ca. 3 mm, 1-veined, margins hyaline, apex acute. Utricles yellow-brownish, obliquely patent, slightly longer than glume, oblong-obovate, plano-convex-trigonous, 3-3.5 mm, herbaceous, densely hispidulous on upper part, indistinctly veined, base cuneate, margins hyaline, apex abruptly contracted into a short beak, orifice obliquely truncate or emarginate.
