Inflorescences 0.4–1 cm × 3–6 mm; bracts inconspicuous, shorter than spikes. Spike 1(–2), gynecandrous, closely approximate, containing 7–15 perigynia, obovoid or suborbicular, 4–7 × 4 mm. Pistillate scales chestnut-brown with lighter center and very narrow hyaline margins, broadly ovate, subequal to perigynia, apex obtuse. Perigynia closely appressed, gray-brown to pale or mid brown, lightly or obscurely several-veined, ovate, 1.5–2 × 1.25 mm, widest near middle, subcoriaceous; beak short, entire.
