Abstract: Enlisting of plant species from the different regions is a continuous and important process in understanding the changes occurring in floral composition over a period of time. Present study enumerated a total of 60 medicinal species of herbs, shrubs and climbers belonging to 34 families from Teraknahalli Reserve Forest area. The plants belong to diverse families with Apocynaceae, Fabaceae, Phyllanthaceae, Rubiaceae, and Solanceae were top five families contributing a sum of 23 species. This shows the richness in species diversity of the present study area. The documented plants have diverse medicinal usage. Total 25 medicinal species were regarded under different Rare Endemic Threatened categories by FRLHT, Bengaluru and IUCN. The study area is under great pressure because of human interference. The reserve forest needs proper management and conservation practices to improve the floral and faunal diversity of the area
