The new species records are: Lasiocephalus lingulatus (Asteraceae); Cardamine vulgaris (Brassicaceae); Lupinus herzogii, Lupinus soratensis (Fabaceae). Other species records, i.e., Calamagrostis sclerantha, Festuca soukupii (Poaceae); Aphanes parvula, Lachemilla tanacetifolia (Rosaceae), and Valeriana mandonii (Valerianaceae), that are mentioned in literature for Peru but have not been acknowledged by the Peru Checklist or the Catalogue of the Flowering Plants and Gymnosperms of Peru are also included. Previous knowledge on the distribution of these species is discussed. Keywords: records, vascular plants, puna, southern Peruvian Andes. Resumen Presentamos 4 nuevos registros y 5 revisiones de registros de especies de plantas vasculares para Perú de pastizales de puna de gran altitud en las cordilleras de Urubamba y Vilcabamba, del sur de Perú. Los nuevos registros de especies son: Lasiocephalus lingulatus (Asteraceae); Cardamine vulgaris (Brassicaceae); Lupinus herzogii, Lupinus soratensis (Fabaceae). Otros registros de especies: Calamagrostis sclerantha, Festuca soukupii (Poaceae); Aphanes parvula, Lachemilla tanacetifolia (Rosaceae), y Valeriana mandonii (Valerianaceae), que son mencionados en la literatura para Perú, pero que no han sido reconocidos por el Checklist de Perú o por el Catálogo de las angiospermas y gimnospermas del Perú, están también incluidos. El conocimiento previo sobre la distribución de estas especies está en discusión. Palabras clave: registros, plantas vasculares, puna, Andes del sur peruano. Introduction High Andean puna grasslands, found above the upper forest-line (ca. > 3800 m.a.s.l.) from northern Peru to Chile (Wilcox et al., 1986; Garcia & Beck, 2006; Montesinos-Tubée et al., 2015 and references therein), have received relatively little floristic attention compared with the paramo grasslands of north-western South America (e.g. Luteyn, 1999; Madriñán et al., 2013; W3TROPICOS-Paramo Flora, 2017). Nevertheless, our recent research over a relatively small area in the southern Peruvian Andes highlights that the high elevation puna remains a veritable treasure trove of taxonomic and ecological novelties waiting to be discovered (Heitkamp et al., 2014; Kessler et al., 2014; Sylvester, 2014; Sylvester et al., 2014a,b; Pfanzelt et al., 2015; Sundue et al., 2015; Ospina et al., 2016; Sylvester et al., 2016a,b). Here we present 230 24 (1): Enero - Junio, 2017 4 new records and 5 overlooked records, belonging to 6 families and 8 genera, of vascular plant species for Peru that we discovered during botanical exploration of the high puna of southern Peru and discuss previous knowledge on the distribution of these species. Material and methods The new and overlooked records were recovered among collections made in the high elevation puna grasslands of the Cordilleras Urubamba and Vilcabamba, southern Peru, between 2010 and 2013, as part of a larger ecological project to reconstruct the potential natural vegetation and soils of these Andean landscapes (see Heitkamp et al., 2014 and Sylvester et al., 2014a for preliminary studies). Species names were checked against the Catalogue of the Flowering Plants and Gymnosperms of Peru (Brako & Zarucchi, 1993), additions Sylvester et al.: Four new and five overlooked records of vascular plants from puna grasslands of the southern Peruvian Andes to this (Vásquez et al., 2002; Ulloa Ulloa et al., 2004; Smith et al., 2005; Rodríguez et al., 2006; Salvador et al., 2008; Linares et al., 2010; Huamantupa et al., 2014; Gonzáles et al., 2011, 2016; Sylvester et al., 2016a), and the online checklist for Peru (W3TROPICOSPeru Checklist, 2017). Results Results: New species records for Peru The 4 new species records for Peru belong to the genera: Lasiocephalus (Asteraceae), Cardamine (Brassicaceae) and Lupinus (Fabaceae). ASTERACEAE Lasiocephalus lingulatus Schltdl., Mag. Neuesten Entdeck. Gesammten Naturk. Ges. Naturf. Freunde Berlin 8: 309. 1814. Fig. 1a. LECTOTYPE: ECUADOR. Humboldt s.n. in Herb. Willd. Cat. No. 16435 (Lectotype: B). Lectotype chosen by Cuatrecasas (1978) but indicated as holotype. Peruvian specimen examined: Dpto. Cusco, prov. La Convención, distrito Vilcabamba, large prominent ledge on the south facing cliff at the end of the TotoraPurkay valley, 4 km east of the TotoraPurkay village, 4536 m, 13°11’00.1’’S, 73°03’07.3’’W, 3-V-2013, S. P. Sylvester 1880 (K!, LPB!, Z!). Notes: Previously considered endemic to the paramos of Ecuador (Luteyn, 1999; Jørgensen & Ulloa Ulloa, 1994). This species was found to be locally frequent in undisturbed open Polylepis woodland intermixed with Calamagrostis and Festuca tussock grassland. BRASSICACEAE Cardamine vulgaris Phil., Linnaea 28: 665. 1858. Fig. 1b. TYPE: CHILE. Philippi s.n. (Holotype: B). Peruvian specimen examined: Dpto. Cusco, prov. La Convencion, distrito Santa Teresa, grazed slopes, nestled in-between rocks, in the central Phacchaq valley on the east side of the river, Yanama, 4245 m, 13°15’40.2”S, 72°50’18.5”W, 4-V-2012, S. P. Sylvester 1545 (CUZ!, MO!, Z!). Notes: Previously known from Argentina and Chile (Zuloaga & Morrone, 1997). TROPICOS.ORG (2017) also lists the specimen Sagástegui et al. 12095 for the region of Cajamarca, prov. Celendin. This species was found infrequent in open grazed puna grassland.
