Description

Leaves are shorter than the stem, with blades that are greenish, linear, slightly curved, with scabrous margins. Inflorescence is dense, oblong-ovate or subglobose. Female glumes are brown, broadly ovate-lanceolate. Utricles are yellowish, much longer and broader than glume, ovate when young, and strongly inflated globose or elliptic at maturity, 1–1.5 × 0.5–1 cm, membranous, yellowish orange or brownish veined, with a rounded base and an apex contracted into a short beak. Flowers and fruits between April and May.[3]
