Abstract Floral diversity is affected by external factors like fire, grazing, pest, invasive species and especially by the man-made activities. This study was conducted at the forest of Sansarpur, Koraon, Allahabad, Uttar Pradesh, India. For identification of floristic composition, quadrats were laid down and samples of all species of trees, shrubs, herbs, climbers and epiphytes were collected and identified with the help of Flora of Allahabad, Flora of Uttar Pradesh, Herbarium of the Botany Department of Allahabad University and various floras and monographs. Classification of the plants has been done on the basis of perrenating buds on the plants and the degree of their protection during adverse conditions and the biological spectrum is prepared on the basis of the percentage of each life-form following Raunkiaer (1934). A total of 138 species belonging to 112 genera and 48 families of angiosperm were recorded in the course of the sampling of vegetation. Out of 48 families, 45 families belong to dicotyledons and remaining 3 belongs to monocotyledons. The dicotyledons comprise 45 families 96 genera and 120 species and monocotyledons comprise 03 families 16 genera and 18 species. Out of the total 138 species dicotyledons represents 86.95% and monocotyledons 13.04%. Dicotyledons comprise a main proportion of the area. Out of a total of 48 families, Fabaceae was the more dominant family followed by Poaceae, Asteraceae, Malvaceae, Euphorbiaceae, Acanthaceae, Combretaceae, Mimosaceae, Caesalpiniaceae and Rubiaceae at the study area. In this study, phanerophytes are more than therophytes. Phanerophytes constituted the main proportion of the vegetation which is 48%, followed by therophytes (34%), chamaephytes (8%), geophytes (6%), hemicryptophytes (3%), and epiphytes(1%).
