A New Taxon of Salvia (Lamiaceae) From Türki̇Ye
- Authors: ÖZgür Eminagaoglu, Melahat Ozcan, Hayal Akyildirim Beğen
  Pages: 167 - 181
  Abstract: Salvia divaricata Montbret & Aucher ex Benth. subsp. artvinense Eminagaoglu, Ozcan & Akyıldırım is described as a new endemic subspecies from Ardanuç (Artvin, Türkiye). It is related to Salvia divaricata Montbret & Aucher ex Benth. and S. tomentosa Mill. from which it differs in stem, leaf characters and flower color and numbers. A key is given to distinguish the new subspecies from the other species in the genus Salvia. Morphology, stem, petiole and leaf anatomy, and nutlet micromorphology were investigated. Nearly rounded stem, hemispherical petiole, bifacial leaf with diacytic stomata, and ovoid to rotund nutlet with glabrous and distinctly rough to protuberances ornamentation were determined for this subspecies. Taxonomic interpretations of the new subspecies are given using morphological, anatomical and phylogenetic analyses. Bangladesh J. Plant Taxon. 29(2): 167-181, 2022 (December)

Genetic Diversity and Relationships Among Medicinal Species of Malva L.
(Malvaceae) Based on Issr Markers
- Authors: Bakhtiar Saadey Ghafoor , Sahar Hussein Hamarashid
  Pages: 193 - 202
  Abstract: The genus Malva L., popularly known as mallow, grows spontaneously in almost all of Europe and the Mediterranean region. This genus is morphologically very diverse and its species are used in the treatment of respiratory, urinary, and digestive problems, but some species are hardly distinguishable based on morphological features. We, therefore, performed a molecular data analysis for this genus. Amplification of genomic DNA of 90 randomly selected samples of six species of Malva using 5 primers produced 83 bands, of which 77 were found to be polymorphic (90.99%). The high average PIC and MI values revealed the high capacity of ISSR primers to detect polymorphic loci among Malva species. The genetic similarities of the six collections were estimated from 0.73 to 0.90. ISSR analysis revealed that Malva parviflora and M. vericillata had the lowest similarity whereas, M. neglecta and M. sylvestris had the highest similarity. Bangladesh J.

- Authors: Shayla Sharmin Shetu, Gazi Mosharof Hossain, Saleh Ahammad Khan, Md Abdur Rahim
  Pages: 203 - 240
  Abstract: 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.

  Abstract: 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.
