Spikes 8–10 mm long, all similar, all female or male flowers basal. Perigynia ascending, green to pale brown, ovate, thin-margined, 4–5 mm long including the ca. 1 mm long serrulate beak; stigmas 2. Female scales green to light brown with lighter margins, ca. as long as the perigynia. Achene 2-sided, smaller than the perigynium (Lesica 2012. Manual of Montana Vascular Plants. BRIT Press.
