Abstract/ Executive Summary:

During the floristic explorations in the Sundarbans mangrove forest of Bangladesh, conducted in 2016-2019, the authors collect some specimens of Angiosperms that are finally identified as Cleisostoma simondii (Gagnep.) Seidenf. of Orchidaceae and Volkameria heterophylla Vent. of Lamiaceae. Specimens of C. simondii are further identified as C. simondii var. guandongense Z.H. Tsi. The authors collect some specimens of another angiosperms plant in 2019 from Gazipur district of Bangladesh and confirm their identification as Leucas martinicensis (Jacq.) R. Br. of family Lamiaceae. All of these taxa are recorded here for the first time from Bangladesh. Detailed taxonomic description with notes on ecology, uses, distribution, and distinctness from morphologically similar taxa, photographs, and illustrations are provided.

Start Date: 00-00-2016

End Date: 00-00-2019

Program Area: Development of Host and Medicinal Plants

Commodity: Plant, Diversity

Objectives:

To find is new records of three species and a variety of Angiosperms for Bangladesh.

Methodology:

The plant specimens were collected, processed, and managed using standard herbarium techniques. These specimens were critically examined in the Plant Systematics and Biodiversity Laboratory of Jahangirnagar University. Their taxonomic identification was confirmed through consulting the experts and taxonomic descriptions and keys available in the relevant literature and matching with the voucher specimens of relevant genera and families preserved at Jahangirnagar University Herbarium (JUH) and Bangladesh National Herbarium (DACB), and clear images of the respective voucher specimens available on the websites of different international herbaria. Nomenclatural information and global distribution were fetched from relevant taxonomic publications and the nomenclatural databases of IPNI, The Plant List, and TROPICOS. All voucher specimens of the three species, one of which is delimited up to a variety, are deposited at JUH. The taxonomic descriptions including the photographs and illustrations were produced from the specimens in the field and laboratory.
