Department Of Botany

There is really no discipline that is more tightly intertwined

The Department has started its Degree course in 1955 and P.G. in 1966. The University recognized it as a Research Centre in 1990. Since its inception, the department has maintained a very high profile in teaching and research in Kerala. The department offers Plant Genetic Resources Management as an elective paper at the Degree-level. Biotechnology is being offered as a special paper for M.Sc.

The Department has signed an MOU for collaborative research in association with Coconut Development Board for “Identification of Elite Coconut Palms in Pathanamthitta District”.

The Department has been engaging two ongoing major projects and three minor projects, funded by UGC and KSCSTE. Two major projects have been awarded by KSCSTE recently.

Department is engaging research in many advanced areas of plant science including biotechnology, plant anatomy, soil algae, soil fungi, phytoplankton, pollution assessment, mycorrhizae, mangrove biota, biodiversity etc.

The department is equipped with student and research microscopes with photographic facilities, spectrophotometer, Tissue culture laboratory, Laminar flow chambers, Electrophoretic apparatus, Digital and film cameras, Algal & Fungus culture collection centre, herbarium, Polyhouse, botanical garden for teaching and research.

Department also subscribes front line national and foreign journals in botany.

An exclusive computer laboratory with printing and scanning facilities and class room all networked and connected to WiFi are available.

Regular field trips to Western Ghats, Sea coast and institutes are conducted for on field experience.

Publications & Seminars

The faculty members have more than 90 publications to their credit in the last five years including research articles in national and international Journals. The Department has organized 12 national seminar in different areas of Plant Sciences.

Financial Assistance

In recognition of the teaching and research achievements of department of Botany, Funds for Infrastructure in Science and Technology grant (FIST) from DST were awarded. The department has been renovated and equipped with modern scientific equipments through the above grants.

CATH Herbarium

The department herbarium is designated as Catholicate College Herbarium (CATH Herbarium), which is registered in Herbarium Index of New York Botanical Garden. It is a new initiative for identification, cataloguing and preservation of herbarium specimens.

Interdisciplinary projects

The department has been made collaborations with department of physics and jointly organizing different projects in interdisciplinary theme.

Books Published

Dr. Binoy T Thomas and Dr. V P Thomas published subject based books for the beneficial use of the students.


The DRC Lab functioning in the department serves as a backbone to the rubber growers of Pathanamthitta and neighbouring villages. The actual Dried Rubber Content (DRC) calculated by the lab will enable the farmers to get actual price for their products

The faculty members Dr. Binoy T Thomas & Dr. V P Thomas provide consultancy services in algal and angiosperm identification respectively.

Extension activities

We undertake the supply of hybrid varieties of coconut saplings to the members of Kudumbasree. Hands own training in mushroom cultivation is also conducting for the members of Kudumbasree. The department also organized a fruit exhibition- Pomum 2015. Students could collect and displayed more than 200 varieties of fruits.


The department is equipped with up-to-date addition of most recent books of all branches of plant science and is having a good reading facility. In addition, department has holding of rare books, journals and dissertation. PG classes are also having their own class room library.


Our botanical museum is having collections of plant materials to demonstrate diversity of plant forms, rare fossil collections, algal and fungal materials.

Botany Association

Department also gives more importance to the extracurricular achievement of the students. Every week, one hour programme is arranged to bring their talents.
