Spikes unisexual, 3-9; uppermost 1-3 male, narrowly cylindric; remaining spikes female, single in an involucral bract sheath, oblong or cylindric, densely many flowered, pedunculate, upper peduncles rather short. Female glumes awned. Utricles yellow-green at maturity, eventually horizontally divaricate or deflexed, narrowly lanceolate or elliptic, obtusely trigonous, not inflated, subleathery or leathery, distinctly several veined, base shortly stipitate, apex rather long beaked, orifice long 2-toothed, teeth subulate or awn-shaped, sometimes recurved. Nutlets rather loosely enveloped in utricle; style slender, usually tortuous, base not thickened; stigmas 3.
