Pistillate scales lanceolate, 3–7.5(–9) × 1.6–2.5 mm, narrower that, longer than perigynia, awn to 2–12 mm. Staminate scales oblong-obovate, 4.5–6 × 1.3–2.4 mm, apex bifid to emarginate, at least proximal scales with awn 2–6 mm. Anthers 3.3–5 mm. Perigynia 3.8–6.8 × 1.7–2.3 mm, apex tapering and rounded; beak 0.1–0.3 mm. 2n = 60.

Discussion
T. V. Egorova (1999) included Carex macrochaeta in sect. Scitae. The species commonly has a white or cream tomentum on many roots, although most individuals have at least some roots with a yellowish tomentum. The sectional placement of this species requires further investigation.
Selected References
None.
