Objective of the study was to prepare a comprehensive list with short description of Bryophytes under the class Hepaticopsida and Bryopsida of Boldha garden, Dhaka.

Methodology:

The report was mainly based upon fresh materials collected from different sites of Boldha garden (latitude 23°43'0" and longitude 90°25'9"), Dhaka. The Boldha garden consists of approximately 3.38 acre which was divided into two units named as ‘Psyche’ and ‘Cybele’. The soil was sandy loam to clay type with a pH 6.7 and annual average temperature was maximum 34.5ºC and minimum 11.5ºC. The average rainfall was about 194 cm. From the Boldha garden 200 leafy and thalloid samples were collected during July, 2006 to December, 2007. The classification of identified species followed in this enumeration was that of the system used by Parihar for the class Hepaticopsida and Gangulee for the class Bryopsida.
