Euporbiaceae is the largest family in the Dicotyledon having 26 species whereas Liliaceae is the largest family in Monocotyledon having 18 species. Species presentation in the families varied from 1 to % species belongs to 16 families and 53% species belongs to others 101 families. For each species local name, scientific name, family and habit have been provided. These species are assigned to 117 families. A total of 541 plant species have been recorded from the campus area.
