Abstract/ Executive Summary:

The study was performed in the Baldha garden, Dhaka. Two species from each of the genus Fissidens Hedw. and Hyophila Brid. were dealt with. The species were, Fissidens taxifolius Hedw., F. involutus Wils. ex Mitt., Hyophila perannulata Ren. et Card. and H. rosea Williams reported as new to the Acrocarpous moss flora of Bangladesh. A detailed taxonomic description of each species with location, date of collection, name of collector and artificial keys of species have been provided.

Program Area: Variety and Species

Commodity: Plant

Objectives:

To study the new records of Acrocarpous mosses.

Methodology:

The report was based upon fresh materials collected from Baldha garden, Dhaka. Baldha garden consisted of 2 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. Baldha Garden represents dense vegetation of Bryophytes. Collected fresh materials from Baldha Garden were analyzed, morphological and anatomical features of the specimens as well as other important features were drawn with the help of cameralucida and measured them with the help of previously calibrated oculometer. Species were identified with the help of the book ‘Mosses of eastern India and adjacent regions’. All the specimens collected were preserved in the Bryology Herbarium, Department of Botany, University of Dhaka (DUBH).
