The present research paper has been constructed by the author on the topic of invasive medicinal plants and their uses in East Midnapore (Purba Medinipur) district, West Bengal, India. To construct this paper frequent small sudden field trips throughout the Medinipur have been organised in different season at same place and other places. Transport of crop seeds, food grain, are the main cause of invasiveness of exotic plants (research by author). The vegetation of tourist spots (Digha, Sankarpur and Mandarmoni), town (Tamluk, Haldia, Panskura, Nandakumar and Bajkul) and rail station has been studied carefully. These places are the mostly crowded and temporary and permanent destination of various kinds of people. 37 invasive species have been identified as medicinal value under 34 genera and 20 families. Maximum Species variation has been found under Asteraceae family. In Asteraceae family 8 genera have been identified.

In the setting of ϵ -chainable metric spaces, we introduce ϵ − ρ − σ uniformly local weak contraction and obtain some results on the existence of fixed points. To show the veracity of the results, we also constructed some examples.
