Basal leaves up to 17 cm long, 3.5–4.5 mm wide, with indumentum usually confined to sheath margin; cauline leaves 2, usually 4–7 cm long, up to 4 mm wide; all leaves with obtuse tip and sparsely papillose-serrulate margins. Lower bract herbaceous, of variable length, up to 3 cm long, shorter than inflorescence. Inflorescence of one subsessile and (6–) 8–10 (–15) pedunculate clusters; clusters subcylindrical-ovoid, usually 5–9-flowered. Peduncles ±straight, smooth, c. 0.4 mm in diam., with longest 2.0–3.5 (–5.0) cm long, sometimes with secondary branches. Bracteoles scarious to pale brownish, c. 2 mm long, entire to ciliate. Tepals ±equal, entire, (2.7–) 3.0–3.3 (–3.5) mm long, castaneous brown, with narrow indistinct paler margins. Stamens 6; anthers 1.0–1.3 mm long; filaments 0.4–0.6 mm long; style c 1.0 mm long; stigmas 2.0–2.3 mm long. Capsule obovoid, subacuminate, shorter than perianth; capsule segments 2.2–2.4 × 1.5–1.6 mm. Seeds c. 1.0 mm long, 0.7 mm wide; appendage 0.1–0.2 mm long, fibrillate. |

| Notes: |
There is a herbarium sheet from Brazil, Rio Grande do Sul, S. Leopoldo, Mt Sapucaia, B.Rambo 57059 (S), where a specimen similar to L. ostenii is accompanied by another plant, apparently ±intermediate between L. ostenii and L. ulei. Further material is required to elucidate relationships between the two taxa. |
