| Description: |
Perennials, densely caespitose and ciliate; stems usually 12–35 cm tall. Basal leaves 8–15 cm long, 4–5 mm wide; cauline leaves 2 (–3), 6–8 cm long, 3–4 mm wide; all leaves with obtuse tip and papillose-serrulate margins. Lower bract usually shorter, rarely longer than inflorescence, c. 1–2 (–4) cm long. Inflorescence composed of one subsessile and 3–5 (–7) pedunculate clusters; peduncles smooth, straight to flexuose, 2–4 (–7) cm long, usually without secondary branches; clusters hemispherical to subglobular, not dense, (2–) 4–6 (–8)-flowered. Bracteoles ±ovate, ciliate-fimbriate above, c. 1 mm long. Tepals ±equal, entire,
c. 2.0–2.2 mm long; inner tepals ±obtuse and shortly mucronate; outer tepals ovate-lanceolate; all tepals with broad membranous margin above, and middle part brown to castaneous brown. Anthers 0.5–0.7 mm long; filaments 0.3–0.5 mm long; ovary c. 1.0–1.2 mm long; style 0.4–0.5 mm long; stigmas usually 1.5–2.0 mm long. Capsule oblong-ovoid, slightly trigonous above, usually substantially exceeding tepals, yellowish straw-brown to pale brownish; capsule segments 2.2–2.6 mm long. Seeds c. 1.0 mm long, 0.7–0.8 mm wide; appendage 0.4–0.5 (–0.7) mm long. 2n=12 [12AL], fide H.Nordenskiöld, Hereditas 42: 10–11 (1956); 2n=24, H.Nordenskiöld, pers. comm. |

| Notes: |
A complex of diploid and tetraploid populations characterized by capsules conspicuously exceeding the perianth, few-flowered clusters and ±obtuse, broadly bordered inner tepals. The tetraploid plant (M.Fujita s.n.) has all the typical features of the species, and substantially differs from L. multiflora s. lat. in having seed appendages up to 0.7 mm long. Similar forms with long exserted stigmas and more numerous flowers in clusters are found in Japan. The complex requires further study. |
