Bangladesh is a rich land of biodiversity. About 6000 species of plants are gathered in such a small area of 147570 sq km.
We are trying to introduce the flora of Bangladesh in a pack from the naturalist view, not from the eye of plant-expert. For this, there will be some unwanted mistakes.
Needless to say, pics used in this site are all original. The information is gathered here from the personal notes, collected books and from different websites.
