Abstract: The State of Chhattisgarh has about 44% of its geographical Area Covered with forests. The Koria district in Chhattisgarh lies between 22058’ to 23049’ North latitudes and 810 33’ to 82045’ East longitude. The average rainfall is 121.36 cm. The forest area is 81.23% of Total dist. area. The annual mean temperature is 240C. The temperature varies between 16.20C to 310C. Geologically the area is dominated by upper Gondwana rocks. Which are rich in coal deposit. The highest mountain ranges of the region occupy the northern part of the district. Koria District of Chhattisgarh state has a very rich flora exhibiting diversity of flowering plants. There is no comprehensive description of the flora as well as vascular cryptogams of the district. Some plant species are on the verge of extinction . Keeping these points in view, the present investigation was planned. Present paper deals with floristic account of flowering plants and provides a preliminary analysis of the flowering plants of Koria district. The district harbours 657 species under 439 genera and 119 families of Seed plants (Angiosperms). Of these, 364 species are wild and 293 species are cultivated/planted. D:M (Dicot:Monocot) ratio was found to be 6.00 family-wise, 4.85 genera-wise and 5.19 species-wise. Generic coefficient was found to be 66.81. The Genera:Species ratio was 1:1.496.
