Previous Directors


Prof. A. Abraham (1979-1983) – Founder Director

Prof. A. Abraham (1914-1994), an internationally known cyto-geneticist and well- respected teacher, was the founding Director, whose long cherished dream of establishment of a botanic garden became a reality in 1979. His extraordinary charisma and skill in management, both of which evoked respect in policy makers and scientists alike and his caliber, far sightedness and vision together enabled him to spearhead a team of young people to lay the foundation. He served JNTBGRI as its Director during 1979-1983. He relinquished the post at his own will handing over the baton to his one time colleague, friend and student- Prof. A. N. Namboodiri. Even after retirement, Prof. Abraham continued to show great interest in activities of JNTBGRI and used to attend important meetings as long as his health permitted.

Orchids had a special place of pride in his heart. Along with his student Vatsala, he published a detailed treatise on South Indian orchids (Abraham & Vatsala, 1981) wherein 150 species were described and illustrated. The major orchid collection, which he established in JNTBGRI is fondly named ‘Prof. A. Abraham Orchid House’. He is commemorated by Ischaemum abrahamii Mohanan et al., Luisia abrahamii Vatsala and Thottea abrahamii Mathew et al.


Prof. A.N. Namboodiri (1983-1990)

Prof. A.N. Namboodiri (b. 1930), who succeeded Prof. Abraham as JNTBGRI’s next Director in December 1983, was also a famous cyto-geneticist of eminence with special interest on reproductive biology. He had his Ph. D. from University of Michigan, U. S. A. and joined Kerala University as its faculty in 1966. With his expertise and exposure Prof. Namboodiri took initiatives to prepare and master plan and over all design for the Garden with the assistance of Royal Botanic Gardens, Kew.During his tenure (1983-1990) construction of the main building and laboratory complex and Guest House was completed.

Major conservatories for trees and woody lianas (Arboretum), orchids (Orchidarium), bamboos (Bambusetum) and medicinal plants were also established during his time. When retired in July 1990, Prof. Namboodiri had laid a strong foundation for JNTBGRI to stand on its feet and flourish. He is respectfully commemorated by Dimeria namboodiriana Ravi & Mohanan and Symplocos macrophylla Wall. ex DC. subsp. namboodirianus Sivadasan & Mohanan.


Dr. P. Pushpangadan (1990 – 1999)

Dr. P. Pushpangadan (b. 1944) joined JNTBGRI as its third Director in November 1990. Earlier he worked in Regional Research Laboratory at Jammu and Ministry of Environment & Forests, New Delhi as the Chief Coordinator of an all India programme on ethnobiology. He reorganized the R & D structure into two systems: Garden System and R & D System. The Garden System incorporated the prior Horticulture and Garden Development, whereas R & D system was conveniently divided into 7 divisions: Plant Biotechnology, Microbiology, Phytochemistry, Ethnomedicine, Ethnopharmacology, Conservation Biology and Plant Systematics and Evolutionary Sciences.Creation of new divisions demanded new positions and the whole R & D set up started with full steam by 1992.Conservatories for many special groups of plants, rare and threatened plants etc. were constructed.

A green house and a mist house were constructed for wild edible fruit plants. Rockery and woodland gardens were established. An ethnobotanical garden and a museum were also established. Conservation education received much attention and thus college and school students were frequently given training and awareness classes. Team spirit and good work, which were the hallmark of this period started giving rich dividends in the form of recognitions: NAM S & T recognized JNTBGRI as a potential Center of Excellence in Conservation Biology and Research in Plant Science in 1991. The Institute got accredited to UNCED in 1992. Government of India recognized JNTBGRI as a National Database Center in Ethnobiology in 1992. Became a member of IUCN and BGCI. UNESCO recognized JNTBGRI as a Training Center in taxonomy under Botany 2000 programme. With the support of DBT, Government of India, a National Gene Bank for Medicinal and Aromatic Plants was also established here. Ministry of Environment & Forests, Government of India recognized JNTBGRI as a Center of Excellence in plant conservation. JNTBGRI received its due recognition and accolades during Dr Pushpangadan’s time and national and international agencies supported various projects substantially. Dr Pushpangadan left JNTBGRI in early 1999 to take up an assignment in NBRI, Lucknow. He is remembered by Ischaemum pushpangadanii Ravi et al.


Prof. G. Sreekandan Nair (1999-2001)

Prof. G. Sreekandan Nair (b. 1945), Professor of Horticulture and Plantation Crops, Kerala Agricultural University joined JNTBGRI as its fourth Director in late 1999. He took a lot of interest in medicinal plants, particularly the development of Itty Achyutan Vaidyan’s Garden. He also initiated a project on conservation of Musa varieties in South India. He left JNTBGRI on 8th June 2001 to return to his parental Department.

A much awaited Herbarium complex and a Visitors’ centre under construction. Garden Development and Horticulture Division was reorganised and conservation of specialised groups of plants was brought under Units as a measure for meaningful ex situ conservation.

JNTBGRI also got its place in the BGCI’s Asia net-work under the “Invest in Nature” Programme.
