In India, the study of Taxonomical rank classification and naming of plants in Sanskrit language is much older than that of Latin and Greek languages and the study dates back to Vedic period from 2500 BC to 600 BC. In Rigveda, three groups of plants have been recognised, viz. trees (Briksha), herbs (Osadhi) and creepers (Virudh). These are further classified into flowering, non-flowering, fruit bearing and fruitless plants. Atharva Veda also contains descriptions of many medicinal plants. In the ancient Indian texts, the nomenclature of the plants was generally based on the plant & # 39;s botanical characters and their therapeutic properties. In Rajanighantu, much importance has been given for nomenclature of plants for which seven factors have been described. In Europe botanical nomenclature has a long history from Theophrastus (c. 370-287 BC), Dioscorides (c. 40-90 AD) to Pliny the Elder (23-79 AD). From Mediaeval times, Latin became the universal scientific language (lingua franca) in Europe. With the advancement of time more and more number of plants were explored which were somewhat similar morphologically but varying from each other in one or the other way. Thus, a need of keen morphological description of plants aroused and modern science provided a number of tactics to identify and classify the available flora. So, the methods of nomenclature witnessed a sea change from the ancient times till today's 21st century. So, the present work aims to discuss about the classification of plants is older than the period of the Theophrastus.

Plants are very valuable for the human being in various ways which play an important role in human diet and nutrition. Vegetables are a big source of food for the human community. In the present investigation, the emphasis is given to the plants which are used as a vegetable by human beings. The plant parts such as roots, rhizomes, tubers, bulbs, stems, leaves, flowers, and fruits are used as vegetables. They have eaten with a meal either the salted spiced cooked recipe or as a salad. It provides vitamins, minerals, proteins, carbohydrates, fats, and oils that are necessary for the body. The authors reported 86 plants from 32 families after a detailed investigation of the vegetable market in the study area during 2021 which was used as vegetables for food. Taxonomically Cucurbitaceae, Fabaceae, and Brassicaceae were the most valuable plant families for supporting vegetable production in a selected area. It also indicates the food habit of the population in this area due to their high demand and supply.

The Genus with its 1234 species has worldwide distribution and is native to almost all continents, except several parts of Canada, Arctic and Antarctica poles. The species are widely used for vegetable and medicines. Various species of Solanum are herbs, climbers, undershrubs, shrubs and trees. From India, 64 species have been reported inclusive of cultivars, out of which 16 species possess medicinal properties Species like Solanum lycopersicon, S. melongana, S. spirale, S. tuberosum are widely used as vegetable and other supplementary food recipes whereas in the traditional culture of Northeast India, S nigrum, S. torvum, S. tuberosum, S. violaceum are used as vegetable with the concept of digestion and worm infestation in different names and the natives adapted the cultivation of the concern species in their kitchen gardens for self and family use. To serve the purpose, shoots of S. nigrum and berries of other species are being used whereas in Ayurvedic system of medicine, S. nigrum is described for the preparation of liver related medicines like Kakamachi Ghrit.

Industries discharge their effluents which are rich in solids, may it be in the form of TSS or TDS. These solids affect the other physicochemical parameters of the water body. Present study deals with the investigation of seasonal variation and statistical analyses of the selected parameters, in river Ami, in light of the industrial effluents. The study records that summer season, appears to be the most polluted, that is during the period when the river carries little amount of water. Statistical analysis showed that all the physicochemical parameters were positively correlated except TDS and temperature.
