Four new records for the vascular flora of Bangladesh

Abstract

This study records two species of Pteridophytes, viz., Hemionitis cordata Roxb. ex Hook. & Grev. and Ophioglossum nudicaule L.f. of Pteridaceae and Ophioglossaceae, and two species of Angiosperms, viz., Bacopa australis V.C. Souza and Salvia misella Kunth of Plantaginaceae and Lamiaceae, respectively, for the first time in Bangladesh, based on the plant specimens collected during our recent botanical explorations conducted in selected areas of Bagerhat, Barguna, and Cumilla districts. A detailed taxonomic description with key characters, notes on ecology, uses, distribution, distinctness from other similar taxa, representative specimens examined, and photographs of each of these four species have been provided.

Three new records of lythraceae in the flora of Bangladesh

“…In the last several decades, they have published a significant number of new records as a part of their persistent efforts to discover new plant species from this country. Since the publication of Ahmed et al (2008Ahmed et al ( -2009Ahmed et al ( , 2009 and Siddiqui et al (2007), about 288 new records pertaining to the angiosperms of this country have been made available (e.g., Rahman and Hassan, 2017;Islam and Rahman, 2017;Sourav et al, 2017;Ara and Hassan, 2018;Rahman and Uddin, 2018;Uddin, 2018;Alfasane et al, 2019;Hossain et al, 2020;Sultana and Rahman, 2021;Hossain et al, 2022;Rahman et al, 2022;Sultana et al, 2022;Uddin and Uddin, 2022;Hossain et al, 2023;Rahman et al, 2023). The majority of these new records contain information on the precise locality of the species.…”

“…With the addition of these new records to the 3611 Angiosperm species described in the Encyclopedia of Flora and Fauna of Bangladesh EFFB), edited by Ahmed et al (2008Ahmed et al ( -2009Ahmed et al ( , 2009 and Siddiqui et al (2007), the total number of species of this plant group reported from Bangladeshi territory has now risen to 3899 (Hossain et al 2023;Rahman et al 2023). It means the status of at least 1101 (20.16%) species of Angiosperms in this country is unknown and needs to be explored for adding new data and obtaining a better idea of this country's flora, if Khan's (1977) estimation of 5000 species' occurrence in Bangladesh and all new records for this country reported so far after the publication of EFFB are considered.…”
