Department of Botany, University of Rajshahi, Rajshahi, Bangladesh

Abstract/ Executive Summary:

Assessment of angiosperm weeds of Rajshahi, Bangladesh has been studied. A total of 155 angiosperm weed species under 125 genera and 50 families were recorded. Of these, Magnoliopsida (Dicots) was represented by 138 species under 109 genera and 43 families while Liliopsida (Monocots) was represented by 17 species under 16 genera and 7 families. Asteraceae were the largest family in Magnoliopsida represented by 27 species, and Araceae were the largest family in Liliopsida represented by 6 species. Fifty (50) medicinal plants have been documented with their uses for the cure of more than 61 diseases, and some of these are abscess, asthma, abortion, cough, cold, smallpox, constipation, dysentery, diarrhea, diabetes, eczema, fever, and fracture of bone, headache, heart disease, itches, jaundice, menstrual disease, paralysis, piles, skin diseases, snake-bite, toothache, vomiting, worm, wound and others. This detailed information will be helpful for the pharmacognosist, botanist, ethnobotanist and pharmacologist for the collection and identification of the plant for their research work.

Program Area: Development of Host and Medicinal Plants

Commodity: Weed, Medicinal Plants

Objectives:

The importance of studying local floristic diversity has been realized and carried out in Bangladesh. Recently, conducted the inventorying of angiosperm diversity of Dhamrai Upazilla of Dhaka and Runctia Sal forest of Bangladesh. The present study will be made an inventory of the angiosperm weeds of Rajshahi, Bangladesh.

Methodology:

Assessment of angiosperm weeds growing throughout in the Rajshahi, Bangladesh was carried out from January 2010 to December 2011. A total of 155 species under 125 genera and 50 families were collected and identified. A survey on the determination of the location of different species was made and a list was prepared to be acquainted with the plants available in the selected area. All the species were noted and time to time the areas were visited to see when they flowered. For the morphological study, different types of species were examined again and again in order to see if there was any variation or not. They were collected at flowering stages and herbarium specimens were prepared as vouchers. In this practice standard method was followed. In this regard different types of plant species were collected from different habitats. All the collected plant specimens were kept in the Herbarium, Department of Botany, and University of Rajshahi, Bangladesh.

The collected specimens were identified studying related taxonomic books and booklets from the library of Rajshahi University. The major collected materials were identified and described up to species with the help of were consulted. For the current name and up to date nomenclature were also consulted.
