Spikelets bisexual or staminate, 3�6 mm; staminate scales lanceolate, membranous, pistillate scales ovate-lanceolate, acuminate. Achenes white or gray and/or with black markings, globose or rarely ovoid, 1�2.5(�3) mm, base narrowly constricted, trigonous, apex umbonate, papillate-verrucose, proximal papillae elongate, retrorse, spiculose; hypogynium brownish, bluntly trigonous border, bearing 6 globose tubercles arranged in distinct pairs, usually finely powdery.
