Abstract

Teknaf Wildlife Sanctuary has been explored to assess angioperm diversity using traditional taxonomic techniques during 2010 to 2011. The assessment has resulted inrecording of total 535 angioperm species under 103 familiies and 370 genera. For each species scientific name, Bangla name (whenever available), family and habit are provided. Of 535 species, 178 represented by herbs, 110 by shrubs, 150 by trees, 87 by climbers and 10 by epiphytes. In Magnoliopsida (dicots), Fabaceae is the largest family represented by 38 species, while in Liliopsida (monocots), Poaceae is the largest family represented by 29 species.DOI: http://dx.doi.org/10.3329/bjpt.v20i2.17389Bangladesh J.

Highlights

Teknaf Wildlife Sanctuary, previously declared as game reserve in 1983 under the Bangladesh Wildlife (Preservation) (Amendment Act, 1974), is located in the Teknaf and Ukhia Upazilas of Cox’s Bazar district near Myanmar border
The plant specimens were identified by consulting different Floras and literature, viz., Hooker (1872-1897), Prain (1903), Uddin and Hassan (2004), Siddiqui et al (2007) and Ahmed et al (2008a, 2009a), and by comparing with the herbarium specimens available at Dhaka University Salar Khan Herbarium (DUSH) and Bangladesh National Herbarium (DACB)
Nineteen species including one gymnosperm (Gnetum oblongum) listed as threatened in the Red Data Book of the country have been detected in this sanctuary (Khan et al, 2001)

Summary

Introduction

Teknaf Wildlife Sanctuary, previously declared as game reserve in 1983 under the Bangladesh Wildlife (Preservation) (Amendment Act, 1974), is located in the Teknaf and Ukhia Upazilas of Cox’s Bazar district near Myanmar border. A total of 535 angiosperm species (wild and cultivated) have been identified and presented based on the present study (collection and observation) in the Teknaf Wildlife Sanctuary. For each species scientific name, Bangla name (when available) and family name are provided (Table 1). The Teknaf area has been classified as hill forest dominated by evergreen and deciduous trees.
