Four new and five overlooked records of
vascular plants from high elevation puna
grasslands of the Southern Peruvian Andes
Cuatro nuevos registros y cinco revisiones de plantas
vasculares de pastizales de puna de gran altitud en los
Andes del sur peruano
We present 4 new and 5 overlooked records of vascular plant species for Perú from high
elevation puna grasslands in the Urubamba and Vilcabamba Cordilleras, Southern Perú. The new
species records are: Lasiocephalus lingulatus (Asteraceae); Cardamine zndgaris (Brassicaceae); Lupimis
herzogii, Lupinus soratensis (Fabaceae). Other species records, i.e., Calamagrostis sclerantha. Festuca
soukupii (Poaceae); Aphanes párvula, Lachemilla tanacetifolia (Rosaceae), and Valeriana mandonii
(Valerianaceae), that are mentioned in literature for Perú but have not been acknowledged by the
Perú Checklist or the Catalogue of the Flowering Plants and Gymnosperms ofPeru are also included.
Previous knowledge on the distribution of these species is discussed.
Keywords: records, vascular plants, puna, Southern Peruvian Andes.
