| Description: |
Perennials, (5–) 12–25 (–35) cm tall, caespitose to loosely caespitose; rhizome short or ascending; stolons absent. Basal leaves flat to canaliculate, c. 3–10 cm long, 1.5–3.0 (–4.0) mm wide. Cauline leaves 2–3, c. 3–8 cm long; margins ciliate, ±sparsely and shallowly papillose serrulate; apex obtuse, swollen. Lower bract narrow, erecto-patent, to c. 2 cm long, shorter or longer than inflorescence. Inflorescence usually wholly contracted in a lobulate head c. 1.0–1.8 × 0.8–1.5 cm, of 3–10 dark clusters; clusters c. 9–15-flowered, ovoid-cylindric, ±sessile (rarely some pedunculate). Bracteoles ovate, scarious, to c. 1 mm long, densely ciliate-fimbriate. Tepals ±equal, narrowly lanceolate, acuminate, c. 2.0–2.7 (–3.0) mm long, dark to blackish brown; margins paler, indistinct. Stamens 6; anthers c. 0.5–0.7 mm long; filaments 0.5–0.7 mm long; style 0.4–0.6 mm long; stigmas 0.8–1.2 mm long. Capsule ovoid–ellipsoid, subacute, shorter than perianth, brown to castaneous–brown; capsule segments 1.6–1.9 × 1.2–1.3 mm. Seeds ovoid–ellipsoid, ±brown, 0.8–0.9 (–1.1) mm long, (0.5–) 0.6 mm wide; appendage 0.10–0.15 mm long, fibrillate. 2n=24 [24BL], fide J.Kirschner & B.Křísa, Preslia 51: 334 (1979). |

Map: A.A.Grossheim, Fl. Kavkaza 2(2): map 100 (1940), as L. pseudosudetica. |
| Notes: |
A variable species similar to L. sudetica; the latter has shorter styles and usually unequal tepals. Plants in Turkey exhibit a wider range of tepal length, seed size and anther/filament length ratio. A recently reported chromosome count of 2n=24 from Greece [Mt Piperitsa, 1800–1850 m, A.Strid et al. 19049 (C, LD), fide A.Strid, Taxon 35: 901–902 (1986)] under the name L. sudetica requires further study but may refer to a range extension of L. stenophylla. Another related species is L. abchasica. |
