Fibre dimensions of various wood, bamboo and grass species and miscellaneous fibrous materials of Bangladesh have been studied from time to time in the Pulp and Paper Division of the Forest Research Institute, Chittagong. The data from these studies have been compiled in this review and the species have been graded as very good, good or poor for paper making on the basis of Runkel ratio. Two other properties, viz., flexibility co-efficient and relative fibre length have also been determined, since these properties are reported to be correlated to the tensile strength and tearing resistance of paper. Out of all the species studied, 33 wood, 3 bamboo, 2 grass & 4 miscellaneous species have been found promising for paper making.
