Floristic diversity, whether wild or cultivated, of a region is a reection of vegetation and plant resources. It is only by means of a oristic study that we can achieve the challenging goal of documentation of plant diversity and its conservation and sustainable use.The complication of oristic data are useful in <a href="http://www.thechemlibrary.com/archives/320"></a>
future vegetation studies for reference. Ethnobotanical information has immense importance in understanding the dynamic relationship existing between the ora of region and the sociocultural system. Traditional knowledge associated with plants and their uses by local tribal indigenous people is always helpful in the conservation of biodiversity and traditional cultures associated with a particular tribe. Since time immemorial, mankind has cultivated the habit of observing wild plants for thousands of years and had used them for different purposes.The ethnic tribal communities have adopted the utilization of local plants as the traditional means of healing their health care systems and are broadly used by all sections of the community, whether directly as folk remedies or applied as the modern medicine. Globally, the wild plants have been always preferred by people due to the cheaper prices, easy availability and minimal side effects. Keeping in view the role of the region in the conservation of biodiversity and its varied potential for ecosystem services, the present study was conducted with the specic objectives of quantifying the oristic diversity and ethnobotanical usage of plants.The mean maximum and minimum temperatures range between to C and to C, respectively.The natural vegetation consists of trees, grasses and bushes.The representative forest sites were visited in three trips from to. During eld studies, the detailed relevant data about the plant specimens were recorded.Specimens were collected from eld and were dried, preserved, labelled and mounted on herbarium sheets by following standard herbarium techniques. Specimens were identied using the relevant taxonomic literature was used for the updated nomenclature of taxa.To document the ethnobotanical information of the plant resources of the study area, the questionnaire and semiinterview method was used for collecting indigenous knowledge about the different plant species.The study area was visited on regularly basis and focused was to mainly collect wild plants having economic value.Fieldbased personal ndings also added more information to the research work.The respondents were further asked about their species preference if they utilized a species for multipurpose usagesmedicinal, fodder, vegetableedible fruit, fuelwood or timber purposes.Statistically, the vegetation data was analysed to nd out the relationship between ethnobotanical usage and plant species.The perennial form was predominant over the other forms., where the clusters are distinctly separated. The clusters of plant species grouped in one limb are more similar in usage.However, the cluster limb one and four displayed the maximum dissimilarity with their neighbouring clusters.Moreover, the similarity in usage decreased with the increasing distance between the groups. The dendrogram generated four distinctly separate clusters based on the plant usage.Medicinal, tanningdying and vegetableedible fruit form one arm of the cluster one and other arm is formed by timber wood, fodder and fuelwood plants.Resin yield, herbal tea and poisonous plants formed second, third and fourth clusters of the dendrogram respectively.
