Prince<strong>to</strong>n Univ. Exp. Patagonia, Bot. 8: 302 (1904). T: Chile, Cape Horn, Hermite Is., J.D.Hooker 14; holo: K. Perennials 7–13 cm tall, densely caespi<strong>to</strong>se, densely <strong>to</strong> sparsely hairy; rhizome short, vertical; s<strong>to</strong>lons absent, plant base greyish straw-brown. Upper part of stem 0.3–0.4 mm in diam., arcuate. Basal leaves usually 3–5 cm long, ±flat <strong>to</strong> canaliculate, c. 2.0–3.0 (–3.5) mm wide, acute; margins subglabrous <strong>to</strong> densely ciliate, smooth or very remotely papillose. Cauline leaves (1–) 2, 1.5–3.5 cm long, c. 1.5 mm wide, acute. Lower bract (or uppermost leaf) usually slightly remote from inflorescence, brownish-membranous (or ±herbaceous), hairy, narrow, less than 2 cm long; upper bracts narrowly triangular <strong>to</strong> lanceolate or ovatelanceolate, dark castaneous brown, paler above, c. 0.7–1.0 cm long. Inflorescence small, 1.0–1.5 × 0.7–0.9 cm, nodding, compact, dark castaneous brown, few-flowered. Bracteoles ±lanceolate <strong>to</strong> narrowly triangular, castaneous brown <strong>to</strong> membranous-brownish, paler near apex, usually 2.5–4.0 mm long. Tepals unequal; inner tepals 2.8–3.4 mm long; outer tepals 3.8–4.7 mm long, lacerate ciliate, dark castaneous brown (including bases of ciliae), lanceolate, acuminate, aristate (with a filiform tip). Stamens (0–2) 3; anthers 0.3–0.6 mm long; filaments 0.7–0.8 mm long; style c. 0.2 mm long; stigmas 1.0–1.2 mm long; gynoecium in some flowers rudimentary, but in most there are rudiments of 1 (–2) stamens. Capsule dark brown, ovoid <strong>to</strong> subglobular, subobtuse, shorter than perianth; capsule segments usually 2.0–2.3 × 1.1–1.2 mm. Seeds ellipsoidal, brown; seed-coat not distinct, 1.0–1.1 mm long, 0.6–0.7 mm wide; appendage yellowish, 0.10–0.15 mm long, fibrillate.

Bot. 17: 150–154 (1976)], but closer <strong>to</strong> the L. racemosa group. Distinct from the former in having three stamens and dark, nodding inflorescence, from the latter it can be distingushed by the compact inflorescence and much longer tepals. 44. <strong>Luzula</strong> ruiz-lealii Barros, Darwiniana 10: 346 (1953) T: Argentina, Mendoza, Tunuyán, Valle del Al<strong>to</strong> Tunuyán, 16 Feb 1934, A.Ruíz Leal 2140; holo: LIL46295. <strong>Luzula</strong> parvula Barros, Darwiniana 10: 356 (1953).
