Abstract/ Executive Summary:

Sir Joseph Dalton Hooker in his first volume of the Flora of British India included 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.

Objectives:

Out of these 44 natural orders, 33 were recorded with 226 species from the area now in Bangladesh. These natural orders of the volume-I and their contributors are listed below in Table 2 with distribution of taxa.

Methodology:

The first volume of the Flora of British India (Hooker, 1872) was considered as an initial step to prepare a list of species which have been recorded in it from the area now in Bangladesh. The recorded area (collection locality), collector’s name, etc. were determined by checking the protologue of each species carefully. The recorded localities, as mentioned in the protologues, were confirmed by consulting Roxburgh (1814, 1832) and Wallich (1828-49) which appeared before the Flora of British India. Moreover, literature including Kurz (1877), Prain (1903), Heinig (1925), Cowan (1926) and Sinclair (1956) appeared after the Flora of British India, were also consulted to ascertain the corresponding places of occurrence in the area of Bangladesh. The current nomenclature of each species was determined as per ICBN by consulting Voss (1983) and by searching Internet sources (I-VI), and taxonomic status were determined following Cronquist’s (1981) system of plant classification. For corrects author citation Brummitt and Powell (1992) was consulted. Synonyms were checked by consulting recently published relevant literature, viz., Khan (1972-1987), Hara and Williamms (1979), Grierson and Long (1984, 1991), Brummitt (1992), Sharma et al. (1993), Sharma and Balakrishnan (1993), Sharma and Sanjapa (1993), Mabberley (1997), Hajra et al. (1997), Hajra (1997), Press et al. (2000), Khan and Rahman (1989-2002), Rahman et al. (2003), Khanam and Ara (2007), and Ahmed et al. (2008a,b;2009a,b,c).

Achievement/Findings:

The search of the first volume of the Flora of British India revealed a total of 226 species under 114 genera and 33 natural orders from the area now in Bangladesh. After current nomenclatural treatment, the number of species reduced to 220. While the genera and families spitted to 131 and 44, respectively. It is determined, so far, that 35 generic names are changed and 79 remain unchanged. On the other hand, 106 species names are changed and 120 remain unchanged. Hence, 220 species and 131 genera under 44 families. are recognized, so far, from the area of Bangladesh.
