Angiosperms in Gobindaganj upazila of Gaibandha district, Bangladesh

Abstract

Angiosperms at Gobindaganj Upazila of Gaibandha district, Bangladesh was studied from January to December 2018. An extensive floristic survey and angiosperms collection have been made throughout the study area. A total of 295 species belonging to 246 genera under 89 families were recorded. Plant habit analysis shows that herbs, shrubs, climbers and trees are represented by 47.45%, 15.93%, 12.20% and 24.40%, respectively. Distribution of angiosperm species in the families shows variation. Asteraceae is the most dominant family represented by 25 species, followed by Fabaceae (19 species), Euphorbiaceae (18 species), Cucurbitaceae (17 species), Acanthaceae (11 species), Solanaceae (11 species), Amaranthaceae (10 species) and Apocynaceae (10 species). 44 families are represented by a single species each while 37 families are represented by 2 to 8 species each. Status of occurrence has been recorded for proper conservation management and sustainable utilization of the taxa which show 218 (73.89%) to be common, 63 (21.35%) as rare, 10 (3.38%) as vulnerable, and 4 (1.35%) are found as endangered in the study area. For each species scientific name, voucher number, Bangla name, English name, habit, status of occurrence and flowering time were recorded.

Diversity of Angiosperm Taxa in Chaar Khidirpur Area of Rajshahi, Bangladesh

“…In addition, the flowering flowers are the most economically vital group of green plants, serving as a supply of pharmaceuticals, fibre products, timber, ornamentals and other commercial products (Ahmed et al, 2008(Ahmed et al, -2009. Important research work on angiospermic plants were carried out in Bangladesh by Rahman (2013), Rahman et al (2007), Rahman et al (2008), Rahman et al (2015), Rahman and Keya (2014), Kona and Rahman (2014), Sultana and Rahman (2016), Sarker and Rahman (2016), Rahman (2017) and Sarker and Rahman (2019).…”

“…1 Corresponding author, Email: oliur.bot@du.ac.bd; prof.oliurrahman@gmail.com In Bangladesh, attempts have been made on floristic and taxonomic studies on plant diversity in different parts of the country since last four decades including some protected areas of the country (Khan et al, 1994;Rahman and Hassan, 1995;Alam et al, 2006;Tutul et al, 2009Tutul et al, , 2010Uddin and Hassan, 2010;Sarker et al, 2013;Mahmudah et al, 2017;Haque et al, 2018;Rashid et al, 2018). Though angiosperm flora of some upazilas were investigated earlier (Moniruzzaman et al, 2012;Rahman et al, 2012Rahman et al, , 2019Rahman and Alam, 2013;Sarker and Rahman, 2019), however, the flora of Dohar upazila has never been explored despite some species are on the verge of extinction due to anthropogenic reasons. The objectives of the present study are to explore angiosperm flora and make a systematic account of the flora of the Dohar upazila.…”
