The family Asteraceae was found to be the largest with 37 taxa, followed by Poaceae with 30 taxa, Ranunculaceae with 24 taxa, Cyperaceae, Caryophyllaceae and Rosaceae each with 17 taxa, Salicaceae with 16 taxa, and Fabaceae with 15 taxa; in total, these comprised 55.1% of all flora complements in this mountain. During the investigation, 5 species were newly recorded in the Khangai mountains forest-steppe region. The most represented life forms in the flora are hemicryptophytes (71.97%), which are common for mountain steppe vegetation. In a time of climate change, effective conservation of nature is needed at an ecosystem such as a single mountain particularly for endemic, relict and other salient species. Furthermore, such a detailed floristic survey is important for finding new records in the field of plant taxonomy and conservation of nature in these specific areas. \u0000Bangladesh J.

The results of this study show that this district houses 664 species under 468 genera and 133 families of vascular plants. The Pteridophytes and Gymnosperms are represented by 21 and five species, whereas, the Magnoliopsida (dicotyledons) and Liliopsida (monocotyledons) of Angiosperms by 494 and 144 species, respectively. About 59.64% of these species are herbs, 15.96% shrubs, 21.69% trees, 2.26% palms and 0.45% bamboos. Total 73.04% of the species are wild, 19.88% planted and 7.08% cultivated. In this area, Fabaceae with 31 species is the largest family, followed by Asteraceae with 27 species, Apocynaceae with 26 species and Malvaceae with 25 and Acanthaceae with 22 species. Ficus with seven species is recorded as the largest genus, which is followed by Solanum, Hygrophila, Euphorbia, Senna, Phyllanthus, Ipomoea, Hibiscus and Alternanthera. Most of the species are found in fallow lands, roadsides, woodlands, homesteads and scrub jungles and useful as medicine, ornamental, fibre, fruit, livestock feed, soil binder and timber. The floristic composition of this district is still rich, though most of its habitats and ecosystems are vulnerable to natural disasters. Effective conservation plan and measures should be adopted for the precious flora of this coastal district. \u0000Bangladesh J.

A total of 90 plant species under 73 genera and 42 families have been recorded from the road dividers of Dhaka city. Analysis showed that among the 90 species, the most abundant plant species in the road divider are Mimusops elengi (Bakul) Polyalthia longifolia (Debdaru), Leucaena leucocephala (Epil-epil), Tabernaemontana divaricata (Togor) and Swietenia mahagoni (Mahagoni). In case of dominant analysis based important value index showed that Mimusops elengi is the top dominant plant species followed by Polyalthia longifolia, Leucaena leucocephala, Tabernaemontana divaricata and Swietenia mahagoni respectively. These plant species have also showed the higher relative density, relative frequency and relative abundance. The percentage of native and exotic species was found here 44% and 56%, respectively. Most abundant and dominant plant species in the road dividers are exotics including Mimusops elengi,Polyalthia longifolia, Leucaena leucocephala and Swietenia mahagoni. Species diversity value was found higher in Hatirjeel site whereas lowest in Baridhara- Badda site. A number of recommendations are made based on the present results for the management of plant species diversity in the road dividers of Dhaka city. Some recommended native plant species for plantation according to the width and soil depth in the road dividers are Cassia fistula, Holarrhena pubescens, Firmiana colorata, Shorea robusta, Miliusa valutina, Butea monosperma, Alstonia scholaris, Toona ciliata, Ficus racemosa, Bombax ceiba, Woodfordia fruticosa, Melastoma malabathricum, Sterculia villosa, Grewia microcos, Syzygium cumini, Tabernaemontana divaricata, Ixora coccinea, Terminalia bellirica, Terminalia arjuna and also native seasonal flowers. \u0000Bangladesh J.

Climate change is altering the environments and likely to result in changes in the distribution of species, flowering times; migrate and adapt to the new environmental conditions; or extinction. Adaptive capacity is the ability of the plants to adapt to the impacts of climate change. Adaptation process is going in nature through phenotypic plasticity, natural selection or migration or polyploidization. The options are not mutually exclusive. Phenotypic plasticity may be the most efficient way of adaptation to a new environment. Polyploidization may increase tolerance to diverse ecological conditions and the high incidence of polyploidy in plants indicates its adaptive significance. Population having polyploid pillar complex is a good backup support towards microevolution and speciation, a mode of adaptation. The paper discusses about these biosystematics approaches towards adaptation to new environmental conditions resulting from climate change. It also discusses about the role of taxonomists under the changed circumstances. It is evident from the review that a set of biosystematics data along with other ecological and conservation information needs to be included in Flora and Monographs. It reveals that it was as far as worked out at the Paris Botanical Congress 1954 and put up by Stebbins in a series of proposals, termed as “Stebbins’ Ten Points” that needs further enrichment. \u0000Bangladesh J.

Western Ghats are the hotspots of biodiversity with rich combination of microbial flora including cyanobacteria. Though cosmopolitan in distribution, their abundance in tropical forests are not fully exploited. To fill up this knowledge gap, the present research was carried out on the cyanobacterial flora of Peruvannamuzhi forest and Janaki forests of Western Ghats in Kozhikode District, North Kerala State, India. Extensive specimen collections were conducted during South-West monsoon (June to September) and North-East monsoon (October to December) in the year 2019. The highest diversity of cyanobacteria was found on rock surfaces. A total of 18 cyanobacterial taxa were identified. Among them filamentous heterocystous forms showed maximum diversity with 10 species followed by non- heterocystous forms with 8 species. The highest number of cyanobacteria were identified from Peruvannamuzhi forest with 15 taxa followed by Janaki forest with 3 taxa. The non- heterocystous cyanobacterial genus Oscillatoria Voucher ex Gomont showed maximum abundance with 4 species. In this study we reported Planktothrix planktonica (Elenkin) Agagnostidis & Komárek 1988, Oscillatoria euboeica Anagnostidis 2001 and Nostoc interbryum Sant’Anna et al. 2007 as three new records from India. \u0000Bangladesh J.

In this study, the genetic diversity among 56 eggplant genotypes from three secondary centers of diversity (Bangladesh, Malaysia and Thailand) was assessed using 11 morphological traits. The experiment was laid in a complete randomized block design with three replications. A wide significant variation was observed for all the morphological traits, and highly significant differences among the three centers of diversity. High heritability and genetic advance was found for different traits i.e. fruit length, fruit diameter, fruit girth, fruit length to width ratio, average fruit weight, number of fruits per plant, fruit yield per plant, plant height and number of primary branches per plant. The selected best traits i.e. number of fruits per plant, average fruit weight and fruit yield per plant showed high heritability along with high genetic advance and less environmental influence but the high value of PCV and GCV. So these traits could be useful for selection criteria in the future breeding program. These results are relevant for evolutionary studies, breeding programs, and management of eggplant genetic resources. \u0000Bangladesh J.
