Carex amphibola Steud.

Plants densely cespitose; rhizo1me internodes 1.2–2 mm thick. Culms dark purple-red to 0.3–2.4(–7.3) cm high or very rarely brown at base, 15–80 cm. Leaves: sheaths glabrous; blades green, widest blades (3.7–)4.4–7 mm wide, smooth abaxially. Inflorescences 0.48–0.93 of culm height; peduncles of lateral spikes glabrous or barely scaberulous; peduncles of terminal spikes 1.6–21(–37) mm, usually barely exceeding lateral spikes; proximal bract sheaths loose, glabrous abaxially, sheath front slightly concave to slightly convex, elongated 0.6–2.2(–5) mm beyond apex; ligules (1.8–)3.4–7.8(–12.9) mm; distal bract much exceeding terminal spike. Spike (3–) 4–5, distal 2–4 overlapping; lateral spikes pistillate, with 3–18 perigynia, 5–26 × 4.6–9.8 mm, ratio of spike length (in mm) to flower number = 1.3–1.9; terminal spikes 7–34 × 1.1–2.7 mm. Pistillate scales 3.7–8 × 1.2–2.4 mm, margins whitish and usually with red-brown speckles, entire, apex with awn 1.1–6 mm. Staminate scales 3.6–4.9 × 1.1–1.9 mm. Anthers 2–2.8 mm. Perigynia spirally imbricate, 52–64-veined, unwrinkled to wrinkled, oblong-lanceoloid to narrowly oblong-ovoid, obtusely triangular in cross section, 4.2–5(–5.2) × 1.5–1.9(–2.2) mm, (2.2–)2.5–3.1 times as long as wide, lustrous, base very gradually tapered, apex gradually tapered; beak absent or straight, 0–0.2 mm. Achenes broadly obovoid to oblong-obovoid, widest at 0.55–0.67(–0.7) of body length, (2.6–)2.8–3.4 × (1.3–)1.5–1.7(–1.8) mm, loosely enveloped by perigynia; stipe straight, (0.3–)0.4–0.6 mm; beak straight, 0.3–0.6 mm.
