Dharmapuri and Krishnagiri districts of Tamilnadu are located in the northwest corner of Tamilnadu. They are part of Deccan plateau and Mysore table land, occupied at an altitude of 300-1200m. The vegetation is scrub jungle and dry deciduous forest. 1200 species of flowering plants belonging to 120 families are present in these 2 districts. 237 species are trees, 136 species are shrubs, 81 species are climbers 485 species are herbs. 258 species are monocotyledons and 945 species are dicotyledons. Fabaceae (Leguminosae) is the largest family with 111 species. Botanical survey of India southern circle Coimbatore (1981-1988) studied the flora of these 2 districts in its flora Tamilnadu analysis. Mathew K.M. (1981-90) Rapinat herbarium Tiruchirapalli made a thorough survey on the flora of these districts. The common trees are listed in the table with common name and local name. Morethan 100 economically important medicinal herbs are distributed here. Rubia cordifolia, Gloriosa superba, Decalepis hamiltonii, Pterocarpus santalinus, Caralluma attennuata, Santalum album, Crataeva magna, Aristolochia indica, Aristolochia bracteolata are rare plants. More than 1000 villages are located in these two districts. The barren unused lands can be planted with native drought resistant trees and shrubs and enrich the green belt around villages. The districts are known for mango and tamarind and tomato. Granite industry is also a major activity here. The Hosur and Denkanikota area is well known for cut flower and vegetable production

The present paper deals with an account of angiospermic taxa of Sidhi district, Madhya Pradesh. A total number of 941 species under 545 genera belonging to 132 families are recorded. Out of these 265 species in 139 genera and 26 families belong to Monocot and 676 species in 406 genera and 106 families belong to Dicot. A perusal of literature has indicated that 272 species collected from Sidhi district have not been earlier recorded from the district.

Six species of plants have been recorded from Akola district, Vidarbh region of Maharashtra as a noteworthy record.

Plant diversity study was carried out in limestone mine dump, quartz sand dump and their adjoining area of Cement factory. Phytosociological observations were made through quadrat study in randomised method. The number and type of each species occurring in each quadrat were recorded. The vegetative characters such as basal area, frequency, density, abundance, relative, frequency, relative density,relative abundance and importance value index were calculated. The species composition showed that relatively higher diversity in adjoining area. Apluda aristata showed maximum IVI in adjoining area and limestone mine dump. In quartz sand dump, Apluda aristata registered maximum IVI.
