A preliminary assessment of the angiospermic plants of "Kapla beel" wetland of Barpeta district of Assam, India

The present paper deals with the study of wetland plants in "Kapla beel" area of the Barpeta district of Assam (India). A total of 107 angiospermic plant species belonging to 80 genera, 37 families, and 21 orders are taken into consideration. Treatment of taxa according to the APG-IV system of classification reveals the existence of 4 ANA-grade species. The clade Magnoliids has been recorded with only a single species. The clade Commelinids is recorded with 50 species under 37 genera, 12 families and 5 orders. Asterids under the principal clade Eudicots and Superasterids respectively have been recorded with 31 species distributed under 27 genera, 13 families and 6 orders. Another major clade, viz. Rosids under the principal clade Eudicots and Superrosids respectively have been found with 8 species belonging to 6 genera, 5 families and 4 orders. Ranunculales and Proteales are recorded as the smallest group under Eudicots comprising only 1 species each. Caryophyllales have been recorded with 10 species belonging to 4 genera and 2 families. The habitat condition of the wetland has been found to favour the growth of marshy amphibious species in a large amount.
