Abstract:
The environmental gradients such as sunlight, temperature, wind, moisture and rainfall determine the structure and composition of the vegetation of a particular habitat. The plant species diversity mainly relevant to the change of climate of the area. The present paper deals with the plant species diversity in Kolanki hills of Raichur. A total 39 species and 38 genera belonging to different 26 families have been recorded. It is observed that the number of plants was highest in the rainy season and lower in the summer season. Hill flora shows very poor representation of monocotyledons. It is interesting to note that the Fabaceae members are dominant followed by Acanthaceae, Convolvulaceae and Euphorbiaceous.
