| Sumario: | Background and aims: Lowland Mountain Forest is the Yungas district of Argentina most affected by anthropic activities, with Calilegua National Park (Jujuy) being the largest protected area of this forest in Argentina. Fabaceae is one of the main families of Spermatophytes due to its diversity and economic importance and it is also one of the most important families of the Lowland Mountain Forest, because of its number of species and abundance of individuals, and the variety of growth habits. In the Flora of Jujuy, Fabaceae has not been approached. The aim of the study is to present a synthesis of the Fabaceae species from the Lowland Mountain Forest, as a contribution to the knowledge of this family in the province.
M&M: We collected and identified specimens in reproductive state from the Lowland Mountain Forest of the Calilegua National Park. We also revised the collection of the JUA Herbarium and family’s bibliography, recording the species present in Jujuy’s Lowland Mountain Forest (Ledesma, Santa Barbara and San Pedro departments), and Flora del Cono Sur (http://www.darwin.edu.ar/proyectos/floraargentina/fa.htm), Documentae Florae Australis (https://www.darwin.edu.ar/iris) and Tropicos databases (https://www.tropicos.org/home).
Results and Conclusions: We registered 48 genera and 92 species, 47 of which are in the Calilegua National Park. Centrosema variifolium was collected for the first time for Jujuy and second for Argentina. Sesbania exasperata mentioned as a novelty for Jujuy. The distribution of Vachellia albicorticata and Senna obtusifolia is extended. Many of the species are in a state of conservation concern, due to clearing and logging activities. |
