A leafy liverwort, Jungermannia exertifolia Steph. (Hepaticae, Jungermanniales,) has been reported from the Adampur Forest of Moulvibazar district as a new species record for Bangladesh. Jungermannia exertifolia is characterized by its flattened leaves and rhizoids arising ventrally all along the stem with alternate leaves, which are obliquely inserted and succubous in arrangement. It grows in the shady habitats of Adampur forest on the surface of the hilly rocks. Detailed taxonomy of the newly reported species along with its photographs is provided. Bryophytes are the one of the most important group of plants consisting of about 24,000 species worldwide with a wide range of distribution. These cosmopolitan species are distributed from the polar region to the tropics(1). They grow especially in hills and forests throughout the year. Bangladesh is plentiful in terms of bryophytes growing area. Bryophytes represents one of the richest groups of the plants in Bangladesh and occupy a wide range of substrata. Recently 248 species of bryophytes from 73 genera under 34 families have been documented(2). Considering the traditional medicinal and food value of bryophytes a very few studies were carried out. Distichophyllum schmidtii Broth., a Pleurocarpous moss and Funaria hygrometrica Hedw., an Acrocarpous moss were two new records from Bangladesh(3,4). Later on 51 species of bryopsida(5) and 48 species of Hepaticopsida and Anthoceropsida from Mymensingh were recorded(6). Despite some sporadic studies on some groups of Bryophytes carried out in the recent past, much effort need to be made to explore the bryophyte flora of the country. The leafy liverworts Jungermanniales is the largest order of the Class Hepaticae represented by 275 genera and 7,000 species(7-9). However, there have no records of Jungermannia from Bangladesh but the genus was reported from the neighbouring countries i.e. Nepal and India(8,9). Recently a taxonomic field survey was carried out to study the bryophytic flora of Adampur Forest of Moulovibazr district in Bangladesh. Specimens of about 20 species of bryophytes were collected from Adampur Forest. *Author for correspondence: <nadra.tabassum@du.ac.bd>.
