<strong>JUNCACEAE</strong> (<strong>Luzula</strong>) 85. ARGENTINA NORTHWEST: Mendoza, Malarhue, Valle de Las Leñas, R.Kiesling & A.Donath 7262, 25 Dec 1989 (SI, MCNS). ARGENTINA SOUTH: Neuquén, Cordillera del Vien<strong>to</strong>, Cerro las Yeguas, A.Pas<strong>to</strong>re 46 (S); Chubut, Lago Vintter, 1360–1450 m, S.Halloy A-93 (LIL); Santa Cruz, Río de las Vueltas, Estancia Pérez, 1200 m, H.Sleumer 1382 (LIL); Santa Cruz, Lago Argentino, 400 m, P.Dusén 5777 (S, SI, UPS). CHILE CENTRAL: Valparaíso, Pe<strong>to</strong>rca, Río Sobrante, 3100–3300 m, J.L.Morrison 17310 (S, SI); La Araucania, Cautín, Volcán Llaima, 1200–1300 m, E.Werdermann 1232 (LIL, S, SI); Valparaíso, Aconcagua, Portillo, 3000 m, E.Wall 1727 (S). CHILE SOUTH: Ñuble, Baños de Chillán, 2100 m, F.W.Pennel 12442 (S, SGO); Libertador, Cordillera del Peuco, 1886, R.A.Philippi (SGO). The obvious type of the name L. chilensis was destroyed in B but details were depicted and described by F.G.P.Buchenau, Junc. S.-Amer. 418 (1879). The seed size, 6 stamens, and inflorescence shape clearly identify L. chilensis. The type of L. rigida does not bear Philippi's annotation of the name but the detailed description (with a number of measurements and individual features) allows identification of the type and its equation with L. chilensis. 39. <strong>Luzula</strong> leiboldii Buchenau, Junc. S.-Amer. 418 (1880) Juncoides leiboldii (Buchenau) Kuntze, Revis. Gen. Pl. 2: 734 (1891). T: Chile, F.E.Leibold 2969; holo: W, not located; iso: S. Illustration: M.Barros, Darwiniana 10: 326, fig. 13 (1953). Perennials 12–30 cm tall, densely caespi<strong>to</strong>se, hairy; base thick, with extravaginal erect shoots; s<strong>to</strong>lons absent. Basal leaves usually 5–10 cm long, 3.5–5.0 mm wide; cauline leaves 1 or 2, 3.5–<strong>6.</strong>0 cm long, 2.0–3.0 mm wide; all leaves acute, rarely subobtuse, with margins ±smooth <strong>to</strong> sparsely papillose, sparsely ciliate. Lower and middle bracts castaneousmembranous, with prominent veins, aristate, ciliate, up <strong>to</strong> 1.5 cm long; upper bracts c. 5 mm, similar <strong>to</strong> tepals. Inflorescence erect <strong>to</strong> suberect, rarely slightly nodding, usually interrupted at base, ‘echinate’ with erec<strong>to</strong>-patent acute bracts, usually 1.5–2.0 (–3.0) cm long, usually of 3–7 few-flowered clusters subtended by conspicuous middle bracts. Bracteoles acuminate, membranous, 2.5–3.0 mm long. Tepals glabrous <strong>to</strong> sparsely ciliate, pale <strong>to</strong> castaneous brown at base, membranous-scarious above, acuminate-aristate, ±unequal; outer tepals 3.5–4.8 mm long; inner tepals 2.7–3.7 mm long. Stamens 6; anthers (0.7–) 0.8–1.2 (–1.5) mm long; filaments 0.4–0.6 mm long; style 0.5–0.6 mm long; stigmas 1.5–2.0 mm long. Capsule ovoid, subacute, deep castaneous, shorter than perianth; capsule segments 2.4–2.9 mm long. Seeds [unripe] 1.5–1.7 mm long, c. 1 mm wide; appendage indistinct, c. 0.1 mm long, fibrillate. Recorded from Santiago province, Chile, and Mendoza and Neuquén, Argentina. 85: AGS, AGW, CLN. Habitat unknown. Map 69. 85. ARGENTINA NORTHWEST: Mendoza, Calmucó, A.Burkart et al. 13849 (SI13849). ARGENTINA SOUTH: Neuquén, Lacar, Cordón del Cerro Colorado (Between Lago Lacar and Lago Lolog), 25 Jan 1986, L.Bernardello & Moscone 620 (CORD). CHILE NORTH: Santiago, Rio Yeso, Lago Negro, 2700 m, W.Biese 937 (LIL); ‘Cordillera de Santiago’, R.A.Philippi (SGO, BM); Santiago, Cerro de Ramón, 2650 m, C.Ysandino (SGO). Closely related <strong>to</strong> L. chilensis, and perhaps only an infraspecific taxon of it. <strong>Luzula</strong> leiboldii is distinct in having longer tepals, longer anthers with higher anther/filament ratio, and tepals sometimes hairy. The material available is <strong>to</strong>o scanty for evaluation of variation ranges. 40. <strong>Luzula</strong> racemosa Desv., J. Bot.
