Purpose: The aims to investigate the angiosperm taxa in the study area. The present research also documented the species diversity and important medicinal plants.  Subjects and Methods: Angiosperm flora in the Chaar Khidirpur area of Rajshahi, Bangladesh was carried out from November 2018 to October 2019 to cover the seasonal variations. Plant parts with either flower or fruits collected using traditional herbarium techniques to make voucher specimens for documentation.  Results: The result focused that a total of 210 species belonging to177 genera under 71 families were recorded. Forty-five (45) medicinal plants were used for the treatment of more than 61 diseases. Conclusion: The present study was the first time to report angiosperm diversity and medicinal plants in the study area. In this research, the status of occurrence has been recorded for proper conservation management and sustainable utilization of the taxa resulting in 81.33% being common, 16.74% as rare and 1.91% are found as threatened in the study area.

Objectives: The present research aimed to document the diversity of herbaceous species in the study area. The study also recorded the status of occurrence and species diversity. Materials and Methods: The work is based on fresh materials collected during eighty-five visits to Rajshahi metropolitan area, Bangladesh from July 2018 to June 2021 to cover the seasonal variations. Plant parts with either flowers or fruits were collected using traditional herbarium techniques to make voucher specimens for documentation. Results: A total of 281 species belonging to 68 families and 246 genera were recorded. 10 Pteridophyta and 58 Angiosperm families are including 13 Liliopsida and 45 Magnoliopsida. Family Asteraceae was the most dominant in all families followed by Acanthaceae, Amaranthaceae, Araceae, Brassicaceae, Euphorbiaceae, Fabaceae, Lamiaceae, Malvaceae, Polygonaceae, Poaceae and Solanaceae. 33 families were monophyletic and had one species and 1 genus each and 23 families are represented by 2 to 5 species each. Conclusion: Out of 281 species, the status of occurrence was recorded for proper conservation management and sustainable utilization of the taxa which show 210 to be common, 61 as rare, 10 are found as threatened species in the study area. The present study will help in identifying the herbaceous vascular taxa for further investigation.

The present research aims to record the traditional knowledge of herbaceous plants used by the local peoples in the Rajshahi metropolitan area of Bangladesh. The field surveys were conducted in July 2018 to June 2021. A total of 63 informants (38 male and 25 female) between 19 and 77 years of age were interviewed. A total of 115 species belonging to 94 genera and 40 families were recorded. In this research, ninety-one human diseases were recorded and treated with various plant species and modes of administration. The current investigation will be useful in identifying the medicinal herbaceous vascular species for future research and also beneficial to evolve the herbal medicines.
