History of the Department of Botany goes back to the decision of the Syndicate of Jahangirnagar University (JU), taken in 1983, to establish the Institute of Life Sciences. As a follow-up of that decision, the aims and objectives and the detail programs of the proposed Institute were finalized and in 1985 the Institute was inaugurated. From 1986, it had begun its historical academic journey with the admission of the students in B.Sc. (Honours) program of two sections, namely Botany and Zoology. In 1989, the Syndicate revised the Statute of the Institute and the Sections were upgraded to full-fledged Departments. In 2001 the Institute had been transformed into the Faculty of Biological Sciences. Thus the Department of Botany was established under the Faculty of Biological Sciences of Jahangirnagar University and as one of the famous Departments of Plant Sciences in this country.
At present, this Department has 24 qualified and experienced academic and 16 non-academic staffs, seven well-equipped laboratories, a common lab cum store room, four classrooms, one seminar library, a botanical garden, a plant conservatory, and more than 250 students.
