Treatment appears in FNA Volume 23. Treatment on page 391. Mentioned on page 379, 389.

Plants cespitose. Culms acutely angled, 75–150 cm, scabrous. Leaves: basal sheaths redbrown; sheaths of proximal leaves bladeless, scabrous, fronts with brown spots, prominently ladder-fibrillose, apex U-shaped; blades 10–15 mm wide. Proximal bract longer than inflorescence, 10–12 mm wide. Spikes erect; staminate 3–4; pistillate 3–5; the proximal pistillate spike 4–13 cm × 5–7 mm, base attenuate. Pistillate scales redbrown, equaling perigynia, apex acute, awnless. Perigynia ascending, pale-brown with redbrown spots throughout, 5–7-veined on each face, somewhat flattened, loosely enclosing achenes, ellipsoid, 3.2–3.5 × 2 mm, dull, apex obtuse or acute, papillose; beak 0.2–0.3 mm. Achenes not constricted, dull.


Phenology: Fruiting Jun.
Habitat: Wet meadows along streams
Elevation: 0–2500 m

Discussion

Carex schottii may be a member of the C. stricta subgroup; it requires additional study. The bladeless, scabrous, ladder-fibrillose sheaths of proximal leaves and the hypostomic leaves indicate a relationship with the group, but the elongate inflorescence bract, 3–4 staminate spikes, and the broad leaves are unique within the group.
