Angiosperm diversity in Bhadrak region of Odisha, India

Abstract

We present the information about angiosperm species in Bhadrak District of Odisha, India. In so doing, we assess the state of floristic knowledge across ecoregions of the district and pinpoint our understanding of the district flora. This study is first of its kind conducted in the district showing current status of the angiosperm diversity. A total of 383 species (262 native species and 121 non-native species) belonging to 282 genera under 93 families are recorded as per APG III classification. These taxa are distributed in 12 superorders and 39 orders; 26.7% of the native species were reported from the superorder Fabids, 20.6% from superorder Malvids, 19.8% from superorder Lamids and 15.6% from superorder Commelinids. One hundred and twenty one non-native species were represented in 12 superorders. Native species of the order Fabales (35), Poales and Lamiales (27) each, Malphigiales (18), Malvales (14), Gentianales (13), Carylophyllales and Solanales (12) each and Myrtales and Sapindales (11) each, account for about 68.7% of the species in the district. Eighty one non-native species belong to these orders. The analysis of the plant species based on growth habits showed highest proportion of herbs followed by trees, shrubs and climbers. Some of the reported species are used for the treatment of various ailments and also for edible purposes. Plant species diversity, distribution and population structure provide baseline information for conservation and sustainable management of available resources.
