New records of angiosperms for the state of Roraima, Brazil

Abstract

Knowledge of the flora of the Brazilian Amazon is very incomplete and many areas are still botanically unexplored. This work reports new records of angiosperms to Roraima from two conservation units in the southwest of the state, the Serra da Mocidade National Park and Niquiá Ecological Station. New records for four genera and 23 species belonging to 15 angiosperm families were found. Leguminosae had the highest number of new records, with five species. The results brought an increase of 0.75% to the angiosperm flora in Roraima, highlighting the need to expand the collection effort throughout the state.
