ABSTRACT

The Juquery State Park (PEJ) is the most important Cerrado remnant in the metropolitan region of São Paulo. It is currently under great pressure caused by the human activities arising from the real estate growth in its surroundings. The present study aims to contribute to the knowledge of Convolvulaceae from PEJ. We analyzed herbarium material and included new collections. Field expeditions were carried out from August 2016 to July 2017. As a result, we recognized 13 species distributed in four genera: Convolvulus L. (one specie), Distimake Raf. (three), Evolvulus L. (one), and Ipomoea L. (eight). It should be noted that two of these species are ruderal, indicating that the Park can be under influence of human activities. An identification key for species is presented, along with descriptions for genera and species, photos, comments on the taxonomy and distribution of each species.
