ABSTRACT
Orchidaceae is one of the largest families of Angiosperms, also being one of the richest and with high degree of endemism in the Atlantic Forest, a biome that includes Mixed Rain Forest and Highland Fields, typical of Campos do Jordão. This study aimed to survey the Orchidaceae species present in four highland fields in an Area of Environmental Protection belonging to the Instituto Presbiteriano Mackenzie in Campos do Jordão, São Paulo State, in the district of Umuarama. Monthly expeditions were made from February 16, 2013 to February 15, 2014. In this period, 12 species belonging to nine genera of Orchidaceae were collected. The most representative genera were Coppensia (three species) and Habenaria (two species), being the remaining genera represented by only one species. Several factors that endanger the integrity of these environments were observed, despite these environments being so little valued and not studied enough.
