Vol. 1: Pteridophytes, Gymnosperms and Liliopsida. Ed. by Md Abul Hassan and Sarder Nasir Uddin. 2018. Many col. figs. in the text & on 16 col. pls. 897 p. Hardcover.

The 'Vascular Flora of Chittagong and Chittagong Hill Tracts' has been prepared under the project, 'Survey of Vascular Flora of Chittagong and the Chittagong Hill Tracts', implemented by the Bangladesh National Herbarium and sponsored by the Ministry of Environment, Forest and Climate Change of the People's Republic of Bangladesh. The project was launched in July 2015 and ended in June 2018. The Flora is an outcome of mostly the field specimens collected by five trained teams worked in five administrative districts of Chattogram Division (viz. Chattogram, Cox's Bazar, Bandarban, Khagrachari and Rangamati). The area is situated at south east corner of Bangladesh. Chattogram was a former district now divided into two districts: namely Chattogram proper at the North and Cox's Bazar at the South. On the other hand, the Chittagong Hill Tracts was another former district now divided into three districts: namely Bandarban, Khagrachari and Rangamati.

This encyclopedic work of vascular flora is the Research Type Flora prepared on the basis of mostly extensive collection of about 40,000 specimens form fields. After processing the specimens from the fields, they are documented and stored at the Bangladesh National Herbarium (BNH) for future reference. In addition to this collection, previous collections deposited at BNH were also examined. Attention was also paid to the extensive major literatures written or edited by Roxburgh (1820-1834), Hooker (1872-1894), Kurz (1877), Pram (1903), Heining (1925), Cowan (1926), Sinclair (1955), Siddiqui et al. (2007) and Ahmed et al. (2007-2009). The Flora attempted to prepare an up-to-date account of most diverse hill flora of Bangladesh.

Along with the native plants naturalized exotic and well established recent introduced garden and crops plants are also included. The Flora of Chittagong and Chittagong Hill Tracts has been written in 3 volumes. In all 2916 vascular plants along with 25 subspecies and 67 varieties under 1210 genera and 225 families have been recorded. Of these, 154 species under 61 genera and 24 families belong to Pteridophytes. Gymnosperms represent by 12 species under 8 genera and 8 families. The remaining taxa belong to the Division Magnoliophyta (Angiosperms). The Class Magnoliopsida (Dicotyledon) represents by 2099 species under 866 genera and 153 families, whereas, the Class Liliopsida (Monocotyledon) represents by 651 species under 275 genera and 40 families. The plant families of Pteridophytes and Gymnosperms are arranged according to the classification of Kramer & Green (1990). On the other hand, the families of Magnoliophyta are arranged according to the Cronquist's (1981) system of flowering plant classification. Piendophytes, Gymnosperms and Liliopsida have been included in Volume 1, along with the introduction. The Magnoliopsida has been included in the Volume 2&3.

All the enumerated taxa are provided with up-to-date name and proper author citation. In available cases, basionym(s) and important synonym(s) are provided also. All known vernacular names are provided for each taxon as for far coined or applied by the common people or the tribal people. The flora provides a uniform description of every taxon in less technical terms. Before the description of each taxon in English, Bangla translation is then given for the use of the common people of the country. Short ecological aspect, use, distribution and state of occurrence are also provided after each description. For identification of every taxon., key has been provided as needed. Photographs are provided for visual identity of important taxa. For each taxon, Flora authorship is mentioned in parenthesis that has prepared or written
