Inflorescences 1.5–4 cm × 4–5 mm; proximal bracts shorter than to exceeding spikes, distal bracts usually scalelike. Spikes 3–6 (–7), gynecandrous, proximal sometimes remote, distal approximate, containing 10–20 perigynia, suborbicular to ovoid, 3–7 × 3–5 mm; terminal spike staminate for 1/2 length, not or scarely clavate.
