Plants with strands of old leaves at base, (5–)10–15(–20) cm. Leaves curving outward from sheath at 30–50° angle, slender, almost terete, equaling or slightly longer than scapes, (5–)10–15(–20) cm; sheath 12.5–21 × 1.8–3 mm, ligule often hoodlike, apically 2-lobed; blade 0.5–1 mm wide, apex acute. Inflorescences: scapes often purple near base, (5–)10–15(–20) cm × 0.5–1(–1.5) mm; thick; racemes (2–)3–5(–7) cm; pedicels 1.4–4 × 0.1 mm. Flowers: tepals somewhat rounded, 1.2–1.5 × 1.1–1.8 mm, apex obtuse; pistils (3–)6–(9–12), 6 fertile. Fruits: fruiting receptacle without wings; schizocarps linear, 3–4 × 1 mm; mericarps linear, weakly ridged, 3–4 × 1 mm, beak recurved, 0.9–1 mm. 2n = 96.

Elevation: 0 m
Distribution
N.B., Nfld. and Labr. (Nfld.), N.S., P.E.I., Que., Maine.
