lower bracts up to 1.5 cm long, ciliate. Inflorescence up to 4–6 cm long, corymbose with
4–20 glomerules on capillary arcuate peduncles c. 0.2 mm in diam., each distally branched;
glomerules usually 3–7-flowered. Bracteoles usually c. 1.5 cm long, ciliolate. Tepals equal,
1.7–2.1 mm long, 0.5–0.6 mm wide, ovate-lanceolate, acute, entire, dark brown. Stamens 6;
anthers 0.3–0.6 mm long; filaments 0.5–0.7 mm long; style c. 0.3 mm long; stigmas c. 1.0 mm
long. Capsule ovoid with subconical top, shorter than tepals; capsule segments dark brown,
lustrous, 1.6–1.8 × 0.9–1.1 mm. Seeds narrowly ellipsoidal, 1.1–1.2 × 0.6 mm, medium

the inflorescence is composed of dense glomerules.

Perennials 8–20 cm tall; rhizome ascending, long, without stolons. Basal leaves 5–8 cm long,
3–4 mm wide; sheath bases straw-brown to dull brownish. Cauline leaves 2(–3), usually
2.5–4.0 cm long, up to 2.5 mm wide. All leaves ±flat with leaf tip subobtuse, often with a
short acute mucro; margins papillose-serrulate. Lower bract short, membranous, brownish at
base. Inflorescence composed of 1–2 sessile and 1–4 pedunculate clusters (these sometimes
composed of a few smaller sessile subclusters, rarely whole inflorescence subcongested);
clusters ellipsoidal, usually 6–7 × 4 mm, pale brown to straw-brown; peduncles capillary,
erect to arcuate. Bracteoles usually 1.5–1.8 mm long, pale brownish to membranous,
fimbriate-ciliate. Tepals subequal (outer longer by 0.2–0.4 mm), 2.0–2.6 mm long, medium
brown with broad membranous to stramineous margin above, entire. Stamens 6; anthers
0.4–0.5 mm long; filaments 0.5–0.7 mm long; style 0.2–0.3 mm long; stigmas c. 0.8 mm
long. Capsule subacuminate, usually shorter than tepals; capsule segments ellipsoidal,
brown, 1.5–1.6 × 1.0 mm. Seeds narrowly ellipsoidal, 0.9–1.0 × 0.5–0.6 mm, brown;
appendage minute, less than 0.1 mm long; base fibrillate. 2n=36 [12'AL', 24'BL'], L.Hämet-
