The Andean ecosystems constitute one of the most important centers of biodiversity in the world; however, their forest covers tend to disappear rapidly as they are subjected to strong anthropic pressure. In this study, the angiosperms present in the forest patches, its edge, and in areas of open vegetation or pasture of an Andean area of the Central Cordillera of Colombia are characterized. General collections of fertile material were made through tours between March 2017 and February 2018. Complementary information was obtained from historic collections deposited in herbaria and the botanical material was deposited in the Herbario Nacional Colombiano (COL). A total of 431 species are recorded, grouped into 92 families and 239 genera, five families of magnolids were found with seven genera and 29 species, 18 monocotyledons (66/131) and 69 eudicotyledons (166/271). The highest species richness is presented by Orchidaceae (54), Rubiaceae (24), Asteraceae (22), Araceae (22), and Piperaceae (20). Terrestrial herbs is the most numerous life form (31.8 %), followed by shrubs (26.5 %) and trees (17.6 %). Despite being areas surrounded by productive activities, mainly agricultural, 30 species are endemic to Colombia, 170 taxa are new records for the eastern slope of the Central mountain range of the department of Antioquia, two are new records for the department, and four new species are reported.
