  1. Name of the Division: BSI

  2. Name of the Scheme: Survey (Botanical)

  3. Brief Introduction and Objectives:

The Botanical Survey of India (BSI) is the apex research organization under the Ministry of Environment & Forests, Govt. of India for carrying out taxonomic and floristic studies on wild plant resources of the country through Survey, Documentation and Conservation.



  • Botanical Survey of India was established on 13th February 1890. Sir George King, the then Superintendent of the Royal Botanic Garden Calcutta, appointed as First ex-officio Honorary Director of the BSI.

  • Almost simultaneously Northern Regional Centre (Saharanpur); Western Regional Centre (Poona); Southern Regional Centre (Madras) and Eastern Regional Centre (Calcutta) were established.

  • By 1910 only Eastern Regional Centre of Calcutta with Superintendent of Garden Remained.

  • In 1939, Mr. C.C. Calder, the last Director of BSI retired.


  • October 14, 1952 – Dr. E. K. Janaki Ammal appointed as Officer on Special Duty (OSD) to draw plans for the revival of Botanical Survey of India.

  • On March 29, 1954 – Plan reorganisation of BSI was accepted by the Government of India with Headquarters at Calcutta with Chief Botanist as its head. In August, 1963 the post of Chief Botanist redesignated as Director, who is ex-officio botanical advisor to the Government of India.

During the successive plan periods, the functional base of Botanical Survey of India was further expanded to include various new areas such as inventorying of endemic, rare and threatened plant species; evolving conservation strategies; studies on fragile ecosystems and protected areas, like sanctuaries, national parks and biosphere reserves; multiplication and maintenance of endemic and threatened plant species, wild ornamentals, etc., in Botanic Gardens and Orchidaria; documentation of traditional knowledge of plants and development of National Database on Herbarium (including type specimens) and live collections, plant distribution and nomenclature, botanical paintings/illustrations, plant uses, etc.

Specific Initiatives with Relevance to CBD: Over the years, the functional role of the Survey was further expanded. After the ratification of the Convention on Biological Diversity (CBD: 1994), Enactment of Biological Diversity Act (2002) and Biological Diversity Rules (2004), BSI has become an important institution as its mandate has direct relevance to Articles 6 (Conservation), 7 (Identification & Monitoring), 9 (Ex situ conservation), 12 (Research & Training), 13 (Public education & Awareness), 17 (Exchange of Information) and 18 (Technical & Scientific Cooperation) of CBD.



  • Exploration, inventorying and documentation of phytodiversity (including non-flowering plants) in general and protected areas, hotspots, fragile ecosystems and sacred groves in particular; publication of National, State and District Floras.

  • Identification of Red list species and species rich areas needing conservation; ex situ conservation of critically threatened taxa in botanical gardens.

  • Survey and documentation of traditional knowledge associated with plants.

  • Develop a National database of Indian plants, including herbarium specimens, live specimens, botanical paintings illustrations etc.


  • Revisionary/Monographic studies on selected plant groups.

  • Qualitative analysis of nutritive value of ethno-food plants and other economically useful species.

  • Capacity building in plant taxonomy through refresher courses and post M.Sc. certificate course.

  • Environment Impact Assessment of areas assigned to BSI for study.

  • Develop and maintain Botanical Gardens, Museum and Herbaria.

  • Preparation of Seed, Pollen and Spore Atlas of Indian Plants.

  1. Activities undertaken so far:

  • Survey and exploration of about 70 per cent of the total geographical areas of the country has been completed for vascular plants. This has resulted into a Repository of about four million National Reference Collections plant specimens with 19100 type specimens.

  • 1 new family, 32 new genera and 925 new species, subspecies, varieties have been discovered as new to science.

  • Inventorying of about 1700 Rare, Endangered and Threatened (RET) species.

  • Live collection of over 1.5 lakh plants in Indian Botanic Garden, Botanic Garden of Indian Republic and associated botanic gardens and National Orchidaria of regional offices.

  • Flowering plants of 7 Biosphere Reserves, 32 National Parks and 23 Tiger Reserves have been documented till date.

  • EIA studies on the impact of over 100 developmental projects on flora have been completed.

  • Traditional knowledge, on plants, associated with all tribes belonging to 41 districts of Bihar Jharkhand, Karnataka, Orissa and Rajasthan, and over 114 tribes belonging to Andaman & Nicobar, Andhra Pradesh, Arunachal Pradesh, Assam, Jammu & Kashmir, Madhya Pradesh, Chhattisgarh, Sikkim, Tamil Nadu, Tripura, Uttar Pradesh, Uttaranchal and West Bengal have been documented. 17 books of Ethnobotany have been published by BSI till date.

  • Over 110 research scholars have been trained in different aspects of plant systematics, leading to the award of Doctorate degree by various Indian Universities.

  • Over 3 million herbarium specimens of India & nearly 2 lakhs of them from different adjoining countries and rest of the World. These includes 16 thousand type specimens (original material based on species new to science and

  • Over 18 thousand exhibits, tannins, dies, oils, fibres, timbers, medicinal, beverages, vegetables, food, and tribal artifacts in Kolkata and all Circle Offices.

  1. Progress/Achievements made during April – December, 2013


Field tours and Herbarium consultation tours:

Seventy Five field tours for collection of plant specimens/materials for floristic, ethnobotanical and pharmacognostical studies on flowering and non-flowering plants were undertaken by different regional centre and units of BSI covering the following regions, including three biodiversity hotspot, viz. the Himalaya, the Indo-Burma and the Western Ghats-Sri Lanka. These include 26 protected areas and 07 Sacred Groves. In addition, 09 tours for the collections of live germplasm were also undertaken in these areas.

  • Western Himalaya: Uttarakhand (in and around Sonanadi Wildlife Sanctuary, Namik and Hiramani glacier valleys, Pithoragarh, Kumaon);

About 3,027 saplings, seeds, propagules belonging to 432 species of rare, threatened, endemic and economic plant species, including wild relatives of cultivated plants, aquatic plants, orchids, palms, canes, bamboos, ferns and fern-allies, etc. (Appendix-1), were collected for introduction in AJC Bose Indian Botanic Garden, Howrah and associated botanic gardens of different Regional Centre.


Cultures of Cymbidium tigrinum and Ilex khasiana have been maintained and multiplied. Axenic seed germination of Armodorum senapatianum have been initiated. In vitro propagation protocol has been standardized for the callus, multiple shoots, and root induction in Eremostachys superba. Callusing has been induced in Pittosporum eriocarpum. Seed viability and germination percentage in Eremostachys superba, Pitosporum eriocarpum and Indopiptadenia oudhensis has been studied. Ultra morphological study of different parts of E. superba plants, such as cottony hairs, leaf glandular hairs and stomata, hairs of the apical tuft of seed and pollen has been carried out under SEM.
