This study was carried out to provide the baseline data on the composition and distribution of the angiosperms and to assess their current status in Rajkandi Reserve Forest of Moulvibazar, Bangladesh. The study reports a total of 549 angiosperm species belonging to 123 families, 98 (79.67%) of which consisting of 418 species under 316 genera belong to Magnoliopsida (dicotyledons), and the remaining 25 (20.33%) comprising 132 species of 96 genera to Liliopsida (monocotyledons). Rubiaceae with 30 species is recognized as the largest family in Magnoliopsida followed by Euphorbiaceae with 24 and Fabaceae with 22 species; whereas, in Lilliopsida Poaceae with 32 species is found to be the largest family followed by Cyperaceae and Araceae with 17 and 15 species, respectively. Ficus is found to be the largest genus with 12 species followed by Ipomoea, Cyperus and Dioscorea with five species each. Rajkandi Reserve Forest is dominated by the herbs (284 species) followed by trees (130 species), shrubs (125species), and lianas (10 species). Woodlands are found to be the most common habitat of angiosperms. A total of 387 species growing in this area are found to be economically useful. 25 species listed in Red Data Book of Bangladesh under different threatened categories are found under Lower Risk (LR) category in this study area.

Pteridophytes growing in the Rajkandi Reserve Forest of Moulvibazar district were indentified and a total of 52 species belonging to 30 genera of 20 families have been documented. The family Pteridaceae with nine species was found to be the largest, which was followed by Polypodiaceae with seven, Tectariaceae with six and Thelypteridaceae with five species. The genus Pteris with six species was found as the largest, which was followed by Tectaria with five and Bolbitis, Lygodium and Selaginella, each with 3 species, and the rest of the genera consisted of two or one species. Most of the species were recorded from the woodlands and three species, viz., Tectaria chattagramica and Cyathea gigantea enlisted in Red Data Book of Bangladesh (Khan et al., 2001), were found as common in this reserve forest.Jahangirnagar University J.

In the light of important developments in biodiversity conservation in the global and national arenas over the last decade (2001-2010), this paper appraises the progress in identifying threatened vascular plant species of Bangladesh as a primary step of species diversity conservation. It is argued that, as per the IUCN Red List categories and the Volume 1 of ‘Red Data Book of Vascular Plants of Bangladesh’ published in 2001, only four angiosperm species are threatened (1 Critically Endangered (CR), 1 Endangered (EN), 2 Vulnerable (VU)) in Bangladesh, not 106 vascular species. This account also records that, accordingly to the ‘Encyclopedia of Flora and Fauna of Bangladesh’ (2007-2009; Volumes 5-12), 36 pteridophyte species (all VU; 18.46% of 195 recorded species), 1 gymnosperm species (EN; 14.29% of 7 species), and 449 angiosperm species (30 CR, 126 EN, 293 VU; 12.43% of 3,611 recorded species) are threatened in the country. The paper discusses and explores the importance, limitations and opportunities for red listing of threatened plants of Bangladesh. This account further advocates for a well-planned initiative to effectively complete the Red List of threatened plant species of the country by considering appropriate, established, updated assessment methods; following collaborative approach; and capitalizing on the progress made so far. Such steps may subsequently contribute to the species diversity conservation endeavours in Bangladesh.Keywords: Angiosperm; Biodiversity; Convention on Biological Diversity; Red Data Book; Red List; Vascular plants.DOI: 10.3329/bjpt.v18i1.7844Bangladesh J.

This study has recognized the occurance of a total of 346 species of Angiosperms under 256 genera and 82 families and assessed their current status and distribution in Mirpur area of Dhaka district. Majority of these families, 68 (82.92%) consist of 255 species under 192 genera, belong to Magnoliopsida (dicotyledons), and the rest 14 (17.07%) comprise of 91 species under 64 genera to Liliopsida (monocotyledons). Asteraceae with 18 species is found to be the largest family in Magnoliopsida followed by Euphorbiaceae and Fabaceae consists of 17 species each; while Poaceae is recognized as the largest family with 41 species in Liliopsida followed by Cyperaceae with 19 species. Ficus of Moraceae and Cyperus of Cyperaceae, each consists of 6 species, are found to be the largest genera in Magnoliopsida and Liliopsida, respectively. Total 236 species have been recorded as herbs followed by 58 tree seedlings, 50 shrubs and 2 lianas. Scrub jungles harbouring a total of 90 species are found to be the most common habitat of Angiosperms in the area, which is followed by marginal lands, road sides, grasslands, lake banks, fallow lands, woodlands, river bank, and highland slope and wet lands. A total of 281 economically important species have been determined from the study area. The occurrence of two threatened species, viz. Andrographis paniculata (Burm.f.) Nees and Rauvolfia serpentina (L.) Benth. ex Kurz, listed in the Red Data Book of Bangladesh, is recognized to be Vulnerable (V) in the study area. Jahangirnagar University J. Biol.

The genus Iris Tourn. ex L. of the family Iridaceae Juss. there are 200 different species in the Northern Hemisphere. There are more than 30 species of this genus in the territory of the Republic of Azerbaijan, some of which are endemic to Azerbaijan or the Caucasus. All irises are decorative and used in ornamental gardening. Iris caucasica Stev. (Iris caucasica Hoffm.) and I. lycotis Woronow (Iris iberica subsp. lycotis (Woronow) Takht.) grows on rocky and grassy slopes of The Garagush Mountain. Iris caucasica Stev. is included in the Red Data Book of Nakhchivan AR as an important subcatagory of protection with the status of Lower Risk — LR (a — Conservation Dependent — CD). Iris lycotis Woronow has been to its activity and other abiotics factors, its range is reduced its biology is poorly studied and it is included as an endangered species in the Red Data Book of Nakhchivan AR with the status of Near Threatened — NT. Species included in this category should be enshrined in special protected areas and their biological characteristics should be studied.
