Spikes erect; proximal 3–4 spikes pistillate, 2–4 cm × 4–7 mm, base cuneate or attenuate; terminal 1–3 spikes staminate. Pistillate scales pale red-brown with narrow pale midvein. Perigynia obovoid, 2–3 × 1.2–2 mm, apex rounded; beak pale brown, not more than 0.2 mm, thickened. 2n = 76.

Discussion
Although extensively intergrading along the Arctic coast, Carex aquatilis var. minor and var. aquatilis appear to be distinct; C. aquatilis var. minor has been reported to maintain its distinctive characteristics in cultivation (J. Cayouette and P. Morisset 1986b). It is reported to hybridize with C. bigelowii (= C. ×nearctica M. Raymond).
