Abstract

The floristic composition of a grassland community of Gangraj village was studied during June 2019 to December 2019, with a view to assess the phytodiversity of a grassland community of Mayurbhanj district in the state of Odisha. The experimental site is about 9 kms from North Orissa University and near about 4 kms from Baripada, the district head quarter of Mayurbhanj, Odisha. The climate of the locality was monsoonal with three distinct seasons i.e. summer (March to June), rainy (July to October) and winter (November to February). All the plant specimens encountered from the experimental grassland community were collected in flowering/fruiting stage and indentified taxonomically in consultation with various regional and national flora books. The community comprised of 23 species of which 9 species were grasses and 14 species were non-grasses. They belong to 9 families i.e. Asteraceae, Convolvulaceae, Cyperaceae, Fabaceae, Malvaceae, Onagraceae, Phyllanthaceae, Poaceae and Rubiaceae. Among them, the members of the family Poaceae showed high percentage contribution (39.13%) followed by Cyperaceae (13.04%), Asteraceae, Fabaceae, Malvaceae and Rubiaceae (8.69% each) whereas the rest three families i.e. Convolvulaceae, Onagraceae and Phyllanthaceae shared 4.35% each during the study period. This variation in floristic composition in the experimental site might be due to the topography, geographical distribution, soil characteristics, climatic conditions and biotic interference of the locality.
