Substantial works carried out for over nearly fifty years contributed around 200 taxa under 84 genera along Bangladesh coast specially the St. Martin’s Island (SMI) when only intertidal and knee to waist deep seaweeds were collected. Sub-littoral seaweed diversity, their distribution and standing biomass along the coast of the SMI with the assistance of Bangladesh Navy using underwater gears, still photography and videography up to a depth of 15 m, were first studied during March and April 2013. It revealed a total of 40 seaweed taxa of which 16 were browns,12 reds and 12 greens including two new variety Caulerpa chemnitzia var. irregulare Aziz et Alfasane and C. sertularioides var. robusta Aziz et Alfasane. Total taxa were low compared to 1990’s and early 2000’s affected by human activities and that some smaller forms were washed away by current and waves during collections. Depth profile showed occurrence of a total of 31 (77%) taxa within 1 m and 34 (85%) in the next 1 m (within 2 m) have been considered as highly productive zone; 27 (67%) taxa in the next 1 m (3rd 1m) depth have been considered as the medium productive zone. The lower productivity in the 3rd m depth measured was due to low light (only 16% of surface light 1350 μEm-2s-1), high Secchi Depth and TDS, all indicating limited light intensity. The number of organisms at 10 m depth decreased to 17 (42%) taxa and at 15 m depth only 4 (10%) taxa were present. The 10 to 15 m depth studied have been considered as low productive zone for March and April environment. The 4 taxa at 15 m were represented by Peyssonnelia polymorpha, Caulerpa taxifolia, Halimeda discoidea and Dictyota atomaria and considered as highly adaptive seaweeds. Of these P. polymorpha in particular could grow on bare boulders of upper intertidal zone under direct sunlight during lowest tide. The average wet biomass in March and April was 55 g m-2 and 902 g m-2, respectively where browns had highest (291.00 g m-2) followed by greens (118.6 g m-2) and reds (45.10 g m-2). Highest average biomass was at location D (696 g m-2) followed by B (179.90 g m-2), A (175.70 g m-2) and C (74.20 g m-2). Total standing sublittoral wet biomass around the SMI was estimated to be 148.50 metric ton for each month based on collections from a total of 50 sites and contribute mostly by Caulerpa chemnitzia var. irregulare Aziz et Alfasane, C. sertularioides var, robusta Aziz et Alfasane, C. furgusonii, Caulerpa taxifolia and Asparagopsis taxiformis. Higher Shannon-Weiner Index of diversity (H') occurred in March at Zone C (3.152) followed by A (2.778), D (2.284), E (1.95) and a minimum at Zone B (1.53). In contrast, Shannon-Weiner Index of diversity (H') showed the higher values at Zone F (2.60) followed by C (1.87), B (1.47), D (1.21) and Zone A showed minimum value (<1). Green seaweed diversity was higher among the classes. The Jaccard similarity index showed slightly higher percentage between Zone A and C (28%) than between Zone C and D (2
近五十年来进行的大量工作在孟加拉国海岸，特别是圣马丁岛（SMI），贡献了84属下的约200个分类群，当时只收集了潮间带和齐腰深的海藻。2013年3月和4月，在孟加拉国海军的协助下，首次研究了SMI沿岸的近海海藻多样性、分布和直立生物量，使用水下设备、静止摄影和视频拍摄，深度可达15米。共揭示了40个海藻类群，其中16个为棕色、12个为红色和12个为绿色，其中包括两个新品种Caulpa chemnitzia var.Irregular Aziz et Alfasane和C.sertularioides var.robusta Aziz等人Alfasane。与20世纪90年代和2000年代初相比，受人类活动的影响，总分类群较低，一些较小的分类群在采集过程中被洋流和波浪冲走。深度剖面显示，在1m内共有31个（77%）分类群，在接下来的1m内（2m内）有34个（85%）分类群被认为是高产区；在接下来的1m（第三个1m）深度内有27个（67%）分类群被认为是中等生产力区。测得的3米深度的生产率较低是由于低光照（仅为表面光照1350μEm-2s-1的16%）、高Secchi深度和TDS，所有这些都表明光强度有限。10米深处的生物数量减少到17个（42%）分类群，15米深处只有4个（10%）分类群。研究的10至15m深度被认为是3月和4月环境的低产区。在15m的4个分类群中，以多型佩松藻（Peyssonnelia polymorpha）、宽叶藻（Caulperpa taxifolia）、盘花藻（Halimeda discoeidea）和大齿网藻（Dictyota atomaria）为代表，被认为是高度适应性的海藻。在这些P.polymorpha中，在最低潮的阳光直射下，尤其可以生长在潮间带上部裸露的巨石上。3月和4月的平均湿生物量分别为55克m-2和902克m-2，其中棕色生物量最高（291.00克m-2），其次是绿色生物量（118.6g m-2）和红色生物量（45.10g m-2）。平均生物量最高的是位置D（696 g m-2），其次是B（179.90 g m-2，175.70 g m-2和C（74.20 g m-2。根据从总共50个地点收集的数据，SMI周围的总直立海底湿生物量估计为每月148.50公吨，主要由化学斑蝥（Caulpa chemnitzia var.Irregular Aziz et Alfasane）、C.sertularioides var、robusta Aziz等人Alfasanne、C.furgussoni、Caulpa taxifolia和Aspagopsis taxiformis贡献。3月份，C区（3.152）的Shannon Weiner多样性指数（H'）较高，其次是A区（2.778）、D区（2.284）、E区（1.95），B区最低（1.53）。相比之下，F区的Shannon Weiner多样性指数（H'）较高（2.60），其次是C区（1.87）、B区（1.47）、D（1.21），A区最低（<1）。绿色海藻的多样性较高。Jaccard相似性指数显示，A区和C区之间的百分比（28%）略高于C区和D区之间的比例（27%），并且发现它们的交叉数为8。孟加拉国植物分类学杂志。29（1）：2022年6月13日至29日

The present study reveals the genetic diversity of Iranian Paracaryum based on morphological and molecular characters of 12 species from 11 provinces of Iran. A total of 118 reproducible bands were generated by 10 of 30 random amplified polymorphic DNA (RAPD) primers, with an average of 11.8 bands per primer and 49% polymorphism. The largest number of effective alleles (Ne), Shannon Index (I) and genetic diversity (H) higher level of Shannon Index (I) and genetic diversity (H) were shown by Paracaryum persicum. Our data depicted the highest similarity between Paracaryum cyclhymenium and P. persicum and the lowest between P. sintenisii and P. bungei. P. bungei showed a relatively low level of genetic variation. Finally, the Neighbor Joining (NJ) trees based on RAPD markers data divided the populations into two different clusters, indicating their genetic difference, which is discussed in detail.

This survey provides the basic taxonomic data on the vascular flora of the disasterprone coastal district of Bagerhat. It has explored the occurrence of 964 species of vascular plants under 607 genera and 147 families in this district. About 68.88% of these species are native and 31.12% are exotic to Bangladesh. Pteridophytes are composed of 32 species under 22 genera of 14 families and Gymnosperms of seven species under six genera and five families. Angiosperms are comprised of 693 species of 450 genera and 99 families of Magnoliopsida (dicotyledons) that represent 71.89% of the flora, and 232 species belonging to 129 genera under 29 families of Liliopsida (monocotyledons) that constitute 24.07% of this flora. Fabaceae with 58 species is the largest dicot family, followed by Asteraceae, Euphorbiaceae, Apocynaceae, and Acanthaceae. Poaceae with 68 species is the largest monocot family, followed by Cyperaceae, Orchidaceae, Araceae and Arecaceae. The genus Cyperus is the largest in the study area, which is followed by Fimbristylis, Euphorbia, Ficus, Solanum and Ipomoea. The species Cipadessa baccifera (Roth) Miq. of Meliaceae is rediscovered in Bangladesh. About 63.35% of species of this flora and most of the Magnoliopsida and Liliopsida are herbs, 18.94% shrubs, 15.63% trees, and 1.55% palms. Nearly 70.81% of the species are wild and the rest are planted or cultivated. 17 species are recognized as rare in the study area due to their very restricted occurrence and poor regeneration. Most of the species grow in the fallow lands, roadsides, woodlands, homesteads, marginal lands and scrub jungles. The majority of the species have more than one uses, but most are useful as medicinals (70.39%) and ornamentals (25.57%). Though the study area is under the stress of different threats, its floristic composition is still rich. We strongly recommend adopting adequate effective measures for the conservation and sustainable development of this rich flora of the coastal region. Bangladesh J.

The ectomycorrhizae of a newly described club fungus Clavariadelphus pakistanicus were collected from Ayubia, Khyber Pakhtunkhwa, Pakistan and described morpho-anatomically. Its Pinus wallichiana associated ectomycorrhizae has been characterized by dichotomously branched, reddish brown color of mature and dark brown to blackish young ectomycorrhizal tips with frequent unbranched and septate emanating hyphae. During molecular and phylogenetic analyses, these mycobionts showed maximum similarity and were clustered with basidiocarps sequences of C. pakistanicus. Hence it was confirmed that these ectomycorrhizae belong to C. pakistanicus and being first time reported from Pakistan. Bangladesh J. Plant Taxon. 29(1): 129-136, 2022 (June)

An ethnomedicinal investigation was conducted from July 2019 to June 2020 in Raipura Upazila, Narshingdi district. The main aim of this study was to record, integrate and document all the scattered distributions of traditional healthcare knowledge of medicinal plants. Data collection of ethnomedicinal plants were performed through key informant interviews, field interviews, checklist interviews, Plant interviews, semi - structured interviews and group discussion. A total of 87 medicinal species with 114 formularies to treat 69 ailments have been recorded. These species belong to 49 families. Most frequently used plant species are trees (43%) followed by herbs (31%), shrubs (21%) and climbers (5%). Oral consumption is the main mode of treatment in the study area followed by external application. The reported ailments were classified into 15 disease categories. Maximum plant species were reported to treat diarrhoea and dysentery. The highest Factor informant consensus (Fic) value was found in respiratory category (fever, cold, cough, pneumonia).The most cited species for this category are Ocimum sanctum L., Nigella sativa L. and Jasticia adhatoda L. Cardiovascular disease showed second highest Fic value. The most cited plant species for this category are Terminalia arjuna (Roxb. ex D.C.) Wight & Arn., Tamarindus indica L. and Allium sativum L. In this survey, 8 species scored 100% Fl values for different disease categories. These are Aerva sanguinolenta (L.) Blume, Neolamarckia cadamba (Roxb.) Bosser, Tamarindus indica L., Momordica charantia L., Cocos nucifera L., Ocimum sanctum L., Leucus aspera (Willd.) Link. and Jasticia adhatoda L. Therefore, such plant species could be further analyzed for bioactive constituents that can lead to discovery of new and potential drugs. The study also revealed that the medicinal plants and traditional knowledge in Raipura Upazila are in threatened condition due to different disturbances and some suggestions have been recommended for conservation.

Asian lotus (Nelumbo nucifera Gaertn.), commonly known as sacred lotus is a basal eudicot. It has been grown and cultivated as food, medicine and for cultural, and religious activities. In the current study, samples were collected from six different locations to evaluate the variation among different lotus germplasm based on external morphological characteristics, as well as, to study the genetic variation and the molecular characterization. Analysis of variance showed a higher level of variations among the germplasm for all the morphological features. Based on the morphological features, a dendrogram was constructed to assess the linkage among the germplasm. The yellow lotus of Cumilla was considered superior among the germplasm studied. To assess the genetic diversity and the correct identification of lotus germplasm, molecular method “Barcoding” was performed. To achieve the goal, two plastidial regions: rpoB and rpoC1 were employed. The germplasm showing successful PCR were subjected to sequence analysis of their barcode genes. All the selected barcode genes showed successful identification of all the germplasm as N. nucifera in multilocus identification based on their sequences except for the germplasm of Rajshahi and also confirmed the yellowish lotus of Cumilla considered as a new cultivar N. nucifera ‘Gomoti’, newly found in Bangladesh. Genetic sequences obtained in the context of DNA barcoding had also been used to create a phylogenetic tree in which the germplasm were clustered into five main clades. The current study was successful in establishing an efficient protocol for the correct identification of lotus germplasm and was capable of establishing an elite gene source. Moreover, future studies are warranted to see the identifying capability and diverging power of the barcodes. Bangladesh J. Plant Taxon. 29(1): 85-95, 2022 (June)
