The Bogdkhan mountain of Mongolia is strictly protected and possesses a unique ecosystem, because of its location in the transitional zone of Siberian taiga and the Asian steppe. Floristic composition and the biological spectrum of the Bogdkhan Mountain were studied during July 2019 to September 2020. A total of 522 vascular plants were recorded belonging to 249 genera and 63 families. Asteraceae was found to be the most dominant family (13.22%; 33 genera and 69 taxa) followed by Poaceae (8.43%; 21 genera and 44). The classified life-form spectra of all the species recorded from the study area revealed the predominance of hemicryptophytes (63.03%) followed by geophytes (11.30%), therophytes (10.34%), phanerophytes (9.58%), chamaephytes (5.36%), and hydrophytes (0.38%). The notable changes found in the biological spectrum, which are chamaephytes from 12 to 5.36%, geophytes from 8 to 11.30% and therophytes from 8 to 10.34%. Variaty of reasons might cause change the life form, such as climate change, anthropogenic impacts, etc. Hemicryptophytes and chamaephytes dominate the flora of the mountain due to the cold mountain niche. The floristic diversity of this mountain tends to decline further videnced from the observed lesser divergence values of geophytes and therophytes. Bangladesh J.

This study provides the basic taxonomic data on the vascular flora of the coastal mangrove ecosystems in Barguna district of Bangladesh. Plant samples and field data have been collected following walk through method. The present study reveals the occurrence of 532 species under 378 genera and 112 families in the study area, of which 24 are true mangroves, 46 mangrove associates and 461 non-mangroves. The pteridophytes are composed of 22 species under 20 genera of 12 families and gymnosperms of two species under two genera and two families. Magnoliopsida are composed of 375 species under 279 genera and 77 families, and Liliopsida of 133 species belonging to 77 genera under 21 families. Fabaceae with 28 species is recorded as the largest dicot family, followed by Asteraceae, Apocynaceae, Euphorbiaceae and Malvaceae. Poaceae with 45 species is the largest monocot family, followed by Cyperaceae, Araceae and Arecaceae. About 60.15% of these species are herbs, 21.80% trees, 15.79% shrubs, 1.88% palms and 0.38% bamboos. The study area composed with 74.06% native and 25.94% exotic species, 79.70% species are wild, 16.35% planted and 3.95% cultivated species. Majority of the species are found to grow in forest margin, roadside, woodland, wetland and river bank. Most of the species are economically useful as medicine, ornamental and vegetable. This study concludes that the floristic composition of coastal mangrove ecosystems of Barguna district is still rich though the area facing some severe threats. This study strongly recommends adopting effective master plan and implementing adequate measures for sustainable conservation and monitoring of the biodiversity of this disaster-prone area.

Consensus in the use of medicinal plants is one of the criteria to find the potential medicinal plants for further in-depth investigation. The present study was conducted with the aim to determine the people consensus in the use of medicinal plants in Thakurgaon district. Data of medicinal plants were recorded using key informant interviews, semi structured interviews and group discussion. A total of 102 medicinal plant species under 49 families with 185 formularies to treat 54 ailments were recorded from the study area. The most frequently utilized plant species are trees (38%) followed by herbs (34%), shrubs (18%) and climbers (10%). The major part used for medicines was leaf. Oral consumption was the main mode of treatment in the study area followed by external application. The top Fic value was obtained in case of heart diseases (0.92). The most cited species used to treat this ailment was Allium sativum, Phyllanthus emblica, Spondias pinnata and Terminalia arjuna. The second highest Fic value was found in respiratory disorders (0.89) followed by cuts and wounds (0.85), skin diseases (0.84) and gastrointestinal disorders (0.81). In case of Fl value, Allium sativum, Spondias pinnata, Cynodon dactylon, Lawsonia inermis, Zingiber officinale, Saccharum officinarum, Tagetes erecta and Baccaurea ramiflora were showed 100%. The species of higher citation frequency were Allium sativum, Phyllanthus emblica, Spondias pinnata, Terminalia arjuna, Cynodon dactylon and Ocimum sanctum. This study recommends that the species which showed high Fic, Fl, Cf values could be used for further phytochemical analysis to investigate active compounds for the discovery of new drugs from medicinal plants.

In this study, the vascular flora of the Lalmai hill area of the Cumilla district has been thoroughly explored. This study reveals the occurrence of 923 species of vascular plants under 594 genera and 141 families in the study area, which represents 23.75% of the total 3886 plant species reported from Bangladesh until now. About 68.15% of these species are native and 31.85% are exotic to Bangladesh. Pteridophytes are represented by 30 species belonging to 21 genera and 11 families, whilst Gymnosperms are represented by eight species under seven genera and six families. Magnoliopsida (dicotyledons) comprises 661 species, including four subspecies and two varieties, from 429 genera and 96 families, accounting for 71.54% of the vascular flora of the study area. Liliopsida (monocotyledons) represents 225 species under 137 genera and 28 families, making up 24.35% of this flora. In Magnoliopsida, Fabaceae with 55 species is the largest dicot family, followed by Asteraceae, Malvaceae, Euphorbiaceae, Lamiaceae and Rubiaceae. Most of the species of Liliopsida (68%) are represented by the five families viz., Poaceae, Cyperaceae, Araceae and Commelinaceae. Poaceae with 75 species is the largest monocot family, followed by Cyperaceae, Orchidaceae, Araceae and Arecaceae. The genus Cyperus is the largest in the study area. The species Antidesma roxburghii Wall. ex Tul. of Phyllanthaceae is rediscovered in Bangladesh. Most of the Magnoliopsida and Liliopsida are herbs (59.80%), which are followed by trees (21.02%), shrubs (17.23%), and palms (1.41%). About 64.57% of the species are recorded as wild, but a significant percentage (27.41%) is planted and cultivated (8.02%). The majority of the species are found to grow in eight categories of habitat viz., roadside, fallow land, homestead, woodland, garden, scrub jungle, agricultural field and grassland. Eight plant species, listed in the Red Data Book of Bangladesh including six as Data Deficient (DD), one Not Evaluated and one Endangered (EN) species, are harboured in the study area. We strongly recommend the adoption of a master plan for minimizing all major threats to the vegetation and habitats of this area and sustainable development, utilization and conservation of its plant resources.

The present study investigated morphological features, leaf and stem anatomy, leaf architecture, epidermal characteristics, and molecular characters of some taxa of Araliaceae to trace out the diversity and the diagnostic significance of these attributes. The studied taxa based on combination of 260 characters representing 182 morphological and 78 molecular characters which were subjected to a numerical analysis using NTSYSPC program. The generated dendrogram explained the similarities and the differences between the examined taxa. The specific similarities are discussed and compared with some current classification systems. The generated dendrogram from morphological attributes confirmed the separation of Aralieae and Schefflerieae as two tribes of Araliaceae and supported the separation of simple leaved taxa from compound leaved.

The studied taxa based on combination of 260 characters representing 182 morphological and 78 molecular characters which were subjected to a numerical analysis using NTSYSPC program. The generated dendrogram explained the similarities and the differences between the examined taxa. The specific similarities are discussed and compared with some current classification systems. The generated dendrogram from morphological attributes confirmed the separation of Aralieae and Schefflerieae as two tribes of Araliaceae and supported the separation of simple leaved taxa from compound leaved.\u0000Bangladesh J.

The present study aims at investigating the vegetation in different sites of Chattogram metropolitan area following appropriate techniques. In order to enumerate the distribution of species, several diversity indices including Shannon-Winer Index, Pielou’s Evenness and Simpson’s Index were employed. A total of 645 species belonging to 414 genera under 120 families were documented from the studied area for the first time. Of these, 37 species (5.73%) are pteridophytes, 607 species (94.11%) are angiosperms and single representation of gymnosperm (0.16%). Among the recorded species, 384 are medicinal species belonging to 277 genera under 93 families. Bacopa monnieri is a dominant species in the forest area with some co-dominant species like Eichhornia crassipes, Centella asiatica, etc. Moreover, this study provides potential sources to the environmental planners, herbalists, ecologists, taxonomists, ethnobotanists, pharmacists, phytochemists and local administration that would help to plan for future green infrastructure and maintain ecosystem function providing long-term benefits for the city dwellers.
