The study aimed at inventorying of threatened plant species of Bangladesh to determine their status of occurrence for emphasizing the setting-up of national conservation strategies and sustainable management. Complete inventory of two families, the Apocynaceae and Vitaceae, has been made and recognized 28 threatened species facing environmental threats, and need sustainable conservation management. The study was based on long-term field investigation, survey of relevant floristic literature and examination of herbarium specimens. An enumeration of threatened taxa is prepared with updated field data on conservation status to include into Red Data Book of Bangladesh.
Sir Joseph Dalton Hooker in his first volume of the Flora of British India includeed a total of 2460 species in 452 genera under 44 natural orders (= families) of which a total of 226 species in 114 genera under 33 natural orders were from the area now in Bangladesh. These taxa are listed with their updated nomenclature and taxonomic status as per ICBN following Cronquist's system of plant classification. The current number recognized, so far, are 220 species in 131 genera under 44 families. The recorded area in Bangladesh and the name of specimen's collector, as in Hook.f., are also provided.
One hundred seventy seven species belonging to 88 genera under 14 natural orders are determined to have been recorded in the third volume of J.D. Hooker's, the Flora of British India from the area now fall in Bangladesh. These taxa are enumerated with updated nomenclature and current taxonomic status following ICN and Cronquist's system of plant classification respectively resulting in 169 species under 93 genera and 14 families. Collection locality with collector's name of each species wherever available, as cited in protologue, is also included.
IntroductionThe plants from the area of Bangladesh included in volumes I and II of J.D. Hooker's, the Flora of British India have already been determined and reported with their updated nomenclature and taxonomic status following ICN Rahman, 2011, 2012). The present report deals with the treatment of the taxa of the volume III of the Flora of British India (1880-1882). This volume includes three parts (VII-IX) published in 3 different dates consisting of a total of 22 natural orders, 354 genera and 2174 species. In this volume, J.D. Hooker was assisted by an eminent botanist, C.B. Clarke. Hooker alone described 4 natural orders while Clarke alone described 18 natural orders. Among these taxa, described in this volume, 177 species belonging to 88 genera and 14 natural orders are determined to be recorded from the area now in Bangladesh. The objective of the study was to update the nomenclature and taxonomic status of the plants of Bangladesh which have been included in the Flora of British India.
The present study was aimed at recognizing the status of 28 endemic plants of Bangladesh and determining their conservation management strategies. These endemics belong to 17 angiosperm families and constitute about 0.78% of the total species of the country. Of these endemics, 2 species were least concern, 10 rare and 7 endangered, and need to give immediate conservation priority. Another 9 endemics were assessed to be extinct since no report of collection for more than 100 years was available and could not be traced in the wild. An enumeration of these endemics is presented, each cited with updated nomenclature, bangla names, type, habit, ecology, potential values, places and status of occurrence, threats to the species, conservation status for sustainable management strategies. List of examined specimens of these endemics, wherever available, is also provided. Photographs of 24 endemics are also presented.

Sir Joseph Dalton Hooker in his second volume of the Flora of British India included a total of 2328 species in 416 genera under 28 natural orders (= families) of which 201 species in 104 genera under 20 natural orders are determined to have been recorded from the area now in Bangladesh. These taxa are listed with their updated nomenclature and taxonomic status as per ICBN following Cronquists system of plant classification. The current nomenclatural treatment revealed a total of 200 species in 109 genera under 25 families to be recognized from the area of Bangladesh. The recorded area and the name of specimens collector, as in the protologue of the Flora of British India, are also provided. DOI: http://dx.doi.org/10.3329/bjpt.v19i2.13133 Bangladesh J.
