The Department of Botany was established in the year 1948 by introducing M.Sc. and Ph.D. programmes. It is one of the oldest science departments of the university. It was started with just 5 students and 3 teachers. The Department has a brilliant history of its growth and development ever since its inception. At present the department has grown to accommodate 40 students in its masters programme. In 1982 the Department also introduced M.Phil. programme. Approximately more than 500 students have received their Ph.D. degree on various topics which is the proof of brilliant academic and research activities of the Department. The Department is housed in a building covering a space of 1408 sq.m. There are well equipped laboratories, museum, herbarium (New York Botanical Garden Acredited - GUBH), seminar hall and departmental library. The Department also has a huge Botanic garden covering an area of 62 acres with more than 500 plant species including rare, endangered and threatened plants. The Department also has an exclusive medicinal plant Garden.

The Department has been selected by the Department of Science & Technology, Govt of India for Financial Assistance under its Infra-structural Development for Science & Technology (DST-FIST) programme (2007-2012). The Department has also been recognized by the University Grants Commission (UGC) for its Special Assistance Programme (SAP) for perusing research on Diversity of rare, endangered and threatened (RET) plants of Assam - their microbial association and conservation.

The Gauhati University Botanical Garden was renamed as Dr. H.K. Baruah Regional Botanical Resource Centre in memory of the founder Professor and Head of the Department, Late Professor H. K. Baruah who was the legendary botanist of the country. The garden was established on 28th August, 1955. Pandit Jawaharlal Nehru (then Prime Minister of India), who inaugurated the main building of the Botany Department on 28th August, 1955, also dedicated this garden for service to the nation. The Garden was developed with an objective to study the rich and diverse flora of N.E. India and to conserve the rare, endangered and threaten plant species of the region. The garden was funded in 1994 by the MoEF (Govt. of India) which was a turning point for its development and converting into an experimental garden.

It is one of the largest and oldest Botanical Gardens of the North East in particular and the country in general. It is spread over an area of ca 62 acres situated in the hills and valleys of Jalukbari hills within the University campus at an altitude ranging from 213 to 247 ft msl.  There are two natural ponds within the garden covering an area more than 1 acre which are replenished by a perennial water stream originating from the peak of the Jalukbari hills.

The Resource centre houses around 500 species of phanerogamic and cryptogamic plants. Some interesting species are Nephenthes khasiana, Vanilla piliferaZammia sp., Brainea insignis, Angiopteris evecta, Cycas pectinata, Taxus baccata, Agathis robusta, Rauvolfia densiflora, Flacourtia jangomas, Baccaurea ramiflora, Magnolia spp., Garcinia spp., Persea bombycina, Ephedra, Aquilaria malaccensis, Mesua assamica, Oroxylum indicum, Sapindus mukorossi, Dillenia indica, Elaeocarpus floribundus, etc. Some of the birds and animals frequently seen in the Garden are monkey, cobra, python, lizards, butterflies, wood pecker, king fisher, robin, cattle egret, etc. Leopard is also present and often observed inside the Garden.

The Garden is regularly visited by students, teachers and researchers from N.E. and other parts of the country. Foreign visitors visiting Guwahati also make a point to visit this garden. The visitors, who wishes to visit the garden, need to take permission from the Head, Dept. of Botany, Gauhati University. Collection of any bio-resource material from the Garden is strictly prohibited and punishable.   



The Herbarium of the Botany Department of Gauhati University (Acronym: GUBH) is accredited by the New York Botanical Garden in April, 2011 (For details, follow the link: It is one of the oldest herbaria in North East India having a collection of ca 18,000 herbarium specimens especially representing the floristic diversity of Brahmaputra valley of Assam, Arunachal Pradesh and neighbouring country Bhutan. More than 20 bamboo species, 350 varieties of rice and around 35 wood samples also been displayed in the museum along with more than other 100 botanical specimens. Besides, some coloured pictorial portrait of medicinal and aromatic plants describing their uses are also kept for display in the Department.

Plant specimen identification and authentication service is rendered (subject to the availability of local reference herbarium specimens) to the researchers on demand and payment of Rs. 50/- per sample. However, proper herbarium specimen along with an application addressing the HoD should submit in the Department of Botany for identification services.
