A floristic survey was carried out in Yungas forest of river basin of San José de Chijra (Jujuy, Argentina). It is the first comprehensive study of plant composition conducted in the area, a region relatively unknown in terms of vegetation. We present a checklist containing 172 species, 127 genera and 51 plant families for the area. 149 are native and 17 are endemic: 3 of Argentina, 11 of NW of Argentina and 3 of the Jujuy province. Families with the most encountered number of species were Asteraceae (50), Solanaceae (13), Fabaceae (12) and Poaceae (8). According to IUCN criteria, seven species are classified as threatened. Our data substantially increase our knowledge of the diversity of the regional flora and will provide an important contribution in developing conservation policy.
