Phytogeographical Affinity Of Barunei Hill, Odisha, India

Abstract

The phytogeography of Barunei Hill provides information on plant species that show strong affinity with nearby states and at the global level. Barunei Hill is a part of the Eastern Ghats discontinuous range of mountains. A total of 149 plant species were enumerated, having 135 genera and 54 families at Barunei Hill. The recorded 149 plant species are compared with the phytogeographical affinity of five states and six nearby countries and continents. The study found that Barunei Hill shares the strongest affinity with Bangladesh (87.24%), Sri Lanka (80.53%), Myanmar (73.15%), Nepal (62.41%), Africa (46.30%), and Australia (38.92%). Barunei Hill also has affinity with Tamil Nadu (47.65%), Andhra Pradesh/Telangana (46.30%), Jharkhand/Bihar (22.14%), West Bengal (20.80%), and Madhya Pradesh/Chhattisgarh (16.77%). A total of 24.83% of the recorded plant species of Barunei hill are present across Countries, and 4.02% are absent in those landmasses. The Phytogeographical study is needed for conservation as it shows how plant species are distributed and related across regions. This Phytogeographical study is needed for conservation as it shows how plant species are distributed and related across regions. In the present study, the plant species of Barunei Hill showed significant affinity with Bangladesh.
