Description Roots glabrous. Culms 15–30 cm × 0.1–0.2 mm. Leaves 26–53 cm × 2.0–5.8 mm largest ones, oldest ones brownish. Inflorescence racemose, dense, 4–10 cm long, with 5–12 androgynous spikes, spreading or dropping. Proximal-most bract 13.6–20.6 cm × 3.1–3.7 mm. Spikes 2.5–4.5(7) cm × 2–4 mm, tightly linear, densely flow-ered, the distal 1/6 segment staminate, with about 150–200 flowers per spike, pe-duncles smooth. Pistillate glumes 3.0–4.1 × 0.7–1.1 mm, obovate to elliptic, dark brown to black, with a light green to hyaline middle longitudinal strip, with nar-row hyaline margins 0.1–0.2 mm that usually do not reach the apex of the glume. Stigmas 2. Utricles 2.1–2.5 × 0.9–1.2 mm, elliptic, brownish-red, smooth, constrict-ed at the apex into a 0.5–0.8 mm long beak, scabrid, shortly bifid with 0.1–0.2 mm long teeth. Nutlets 1.6–1.9 × 0.8–1 mm, ovate to elliptical, not invaginated. [details]

Etymology In honor of Prof. Marcia Waterway, who worked as curator at the McGill University Herbarium and was one of the most relevant researchers on the early molecular exploration of the genus Carex. The epithet translates Marcia’s family name to Lat-in: via (way) and aqua (water). [details]
