SUMMARY:

This study aimed to characterize the angiosperm flora present on the campus of the Agricultural School of Jundiaí (EAJ/UFRN) in Macaíba, Rio Grande do Norte, Brazil, focusing on the Mata do Bebo forest fragment, a key remnant of periurban Semideciduous Seasonal Forest. Data were compiled from four virtual herbarium platforms (Reflora, SpeciesLink, Jabot Geral, and Jabot RB), totaling 1,494 initial records. After screening, 640 records (42.9%) were excluded as duplicates, and 62 records (4.2%) lacking taxonomic identification were set aside for later identification. Thus, 792 valid records (53.0%) were retained for floristic analysis. These valid records resulted in the identification of 100 families, 234 genera, and 292 angiosperm species. The most representative families were Myrtaceae (80 records), Fabaceae (79), Rubiaceae (38), and Asteraceae (33). The most frequent genera included Myrcia, Eugenia, and Psidium. Subsequent taxonomic verification, conducted using the Flora do Brasil and Funga do Brasil databases for nomenclature standardization and updating, resulted in a final validated checklist of 312 records, each associated with a corresponding voucher specimen. Significant nomenclatural changes were noted during this revision. The results highlight the high floristic diversity of the study area, reinforcing the ecological importance of the remnant vegetation at EAJ for regional biodiversity conservation within the Atlantic Forest biome. The future steps also involve suggestions for connections between the remnants of the EAJ, analysis of the neighboring landscape of the Mata do Bebo, and suggestions for conservation of the campus flora.
