Carbon is one of the versatile materials used in modern life for human welfare. It has a wide range of applications such as drug delivery, coatings, energy generation and storage, gas separation, water purification, sensor fabrication, and catalysis. Most of the widely used carbon materials are graphene and carbon nanotubes. Nonrenewable precursors (e.g., natural gas), toxic chemicals, and complex synthesis methods are often required for their preparation, limiting their wide practical applications. Besides these, biomass-derived carbons are attractive materials as they can be prepared simply from renewable biomass. However, their practical applications' success partially depends on their properties like size, shape, porosity, and presence of heteroatoms, which can be controlled by selecting the proper type of biomass, activating agent, and preparation method. It is noted that different species of plants have different chemical compositions and textures. This mini-review summarizes our group's recent sophisticated developments in agricultural-bio-waste-derived carbonaceous materials, including nanomaterials for electrocatalytic water splitting, electrochemical sensors, supercapacitors, water splitting, water treatment, gas separation, and enhance oil recovery. This offers valuable insights and essential guidelines towards the future design of agro-waste derived carbonaceous materials in various applications.

The present study was designed to analyse the anatomy of the vegetative and reproductive parts of Turkish Iberis species from a systematic point of view. Samples of leaves, stems, roots, fruits, and seeds of each species were collected, fixed, and processed according to the paraffin method for light microscopy. The numerical analysis derived from 11 anatomical characteristics showed that the number and dimensions of vessels in the root, presence of aerenchyma in the leaf, number and dimensions of palisade parenchyma, and mesophyll type were useful for grouping the Iberis taxa. The testa was composed of four layers: the epidermis, subepidermis, compact tissue, and parenchyma. The testa thickness was a significant character to distinguish the investigated Iberis species. In this study, the traditional classification of Turkish Iberis species was mostly congruent with the dendrogram generated vegetative anatomical properties. Bangladesh J.

Khadimnagar National Park is one of the reserved secondary forests, located in northern side of Sylhet Sadar Upazila, Bangladesh. Arare, fan-shaped palm species, locally called Aanor or Chatipata has primarily been located in the park. The plants have yetto bear any flowers and fruits. Leaf specimens were collected and studied in plant taxonomy laboratory. The sterile specimens were identified as Livistona jenkinsiana Griff. based on external morphological characters. Further exploration is necessary in Bangladesh to find its population status and distribution record of Livistona jenkisiana Griff. When exploring Khadimnagar national park of Sylhet forest division in 2015 to find out the plant species of conservation worthiness the authors were encountered with a number of palms in the stream sides at the beginning of two hours trail near the forest beat office. The area is deep forest with no disturbance from humanity dominated by a good number of tree species particularly Chapalish (Artocarpus chama Buch.-Ham. ex Wall.), Champa (Michelia champaca L.), Agar (Aquilaria agallocha Roxb.), Shegun (Techtona grandis L. f.), Zybans (Bambusa vulgaris Schrad. ex Wendl.), bushy vegetations, climbers and annual herbaceous plants. Wildlife population including hanuman was encountered during the visit. Among the palm plants, one palm was identified as Pinanga gracilis which was listed earlier as red plant in our country but other one palm with fan-shaped leaves locally called Aanor or Chatipata could not be identified in the field. The authors observed carefully its vegetative growth form and took a number of images from different angles and also collected plant specimens for further study using traditional taxonomic techniques (Hyland 1972; Alexiades 1996). The specimens later were brought to plant taxonomy laboratory, Department of Botany, University of Dhaka where this was thoroughly examined and studied for all morphological properties. The unknown palm species was identified as Livistona jenkinsiana Griffith by matching of its properties with the properties given in the Flora of China (Wu et al., 2007) and Major Jenkin’s palm in Thailand (Barfod et al., 2010). Identification was confirmed by discussing with Professor Anders Sanchez Barfod, Department of Biological Sciences, Aarhus University, Denmark and also authenticated by comparing with Google known images of LivistonaJenkinsianaGriff. The species has primarily been reported as rare species recorded from Bangladesh which belongs to the family Arecaceae. Earlier the species was reported by William Griffith in 1845 from Assam and he mentioned the species may occur in Bangladesh. Very recently Barfod et al. (2010) also mentioned that the species may occur in Bangladesh territory. After W. Griffith a good number of works were done on the flora of Bangladesh including Hooker (1892), Prain (1903), Rahman and Hassan (1995), Uddin et al. (1998), Uddin and Rahman (1999), Khan and Huq (2001), Uddin et al. (200
Khadimnagar国家公园是保留的次生林之一，位于孟加拉国Sylhet Sadar Upazila的北侧。Arare，扇形棕榈物种，当地称为Aanor或Chatipata，主要位于公园内。这些植物尚未结出任何花朵和果实。在植物分类学实验室对叶片标本进行了采集和研究。无菌标本被鉴定为詹金斯氏利文斯顿菌。基于外部形态特征。需要在孟加拉国进行进一步的探索，以找到其人口状况和分布记录。2015年，当作者在Sylhet森林部门的Khadimnagar国家公园探索具有保护价值的植物物种时，在森林巡逻办公室附近两个小时的小径开始时，他们在溪流边遇到了一些棕榈树。该地区是一片深林，没有受到人类的干扰，主要有大量的树种，特别是Chapalish（Artocarpus chama Buch.-Ham.ex Wall.）、Champa（Michelia champaca L.）、Agar（Aquilaria agallocha Roxb.）、Shegun（Techtona grandis L.f.）、Zybans（Bambusa vulgaris Schrad.ex Wendl）、茂密的植被、攀缘植物和一年生草本植物。访问期间遇到了包括哈努曼在内的野生动物种群。在棕榈植物中，有一种棕榈被鉴定为细叶棕，它在我国早些时候被列为红色植物，但另一种当地称为Aanor或Chatipata的扇形叶棕榈在野外无法鉴定。作者仔细观察了它的营养生长形式，从不同角度拍摄了许多图像，还收集了植物标本，以使用传统的分类学技术进行进一步研究（Hyland 1972；Alexiades 1996）。这些标本后来被带到达卡大学植物系植物分类学实验室，在那里对其进行了彻底的检查和研究，以确定其所有形态特征。通过将其特性与《中国植物志》（Wu et al.，2007）和泰国的詹金少校棕榈（Barfod et al.，2010）中给出的特性进行匹配，确定该未知棕榈物种为詹金氏Livingstona jenkinsiana Griffith。通过与丹麦奥胡斯大学生物科学系Anders Sanchez-Barfod教授的讨论，确认了身份，并通过与谷歌已知的LivingstonaJenkinsianaGriff图像进行比较进行了验证。该物种主要被报道为孟加拉国记录的稀有物种，属于槟榔科。1845年，威廉·格里菲斯在阿萨姆邦报告了该物种，他提到该物种可能出现在孟加拉国。最近Barfod等人（2010）也提到该物种可能出现在孟加拉国境内。在W.Griffith之后，对孟加拉国的植物群进行了大量的研究，包括Hooker（1892）、Prain（1903）、Rahman和Hassan（1995）、Uddin等人（1998）、Uddin和Rahman（1999）、Khan和Huq（2001）、Uldin等人（2002）、Udden等人（2005）、Rafiqul等人（2009）、Tutul等人（09）、Udin和Hassan2010）、Arefin等人（2010）、Khondker等人（2010年）和Uddin等人（20112013）。但没有研究人员报告这种来自孟加拉国领土的稀有物种。因此，这种稀有物种主要在

Living specimens of three colour forms (pink, white and yellowish white) of Nelumbo nucifera Gaertn. were observed in different natural habitats of Bangladesh and collected. Fresh specimens were studied in the field as well as in the laboratory. After detailed study it was concluded that the three colour forms available in Bangladesh belong to the same species, Nelumbo nucifera Gaertn. However, the yellowish white colour form, having many stamens petaloid, is considered as a new cultivar Nelumbo nucifera ‘Gomoti’ and reported here as the first lotus cultivar from Bangladesh.

A taxonomic study on the flora of Dohar upazila (sub-district) under Dhaka district has been conducted that results in occurrence of 204 angiosperm taxa under 165 genera and 68 families. Magnoliopsida is represented by 158 taxa distributed in 129 genera and 53 families. In contrast, Liliopsida is constituted by 46 taxa under 36 genera and 15 families. Asteraceae appears to be the largest family in Magnoliopsida consisting of 16 species, whereas Poaceae is the largest family with 16 species in Liliopsida. In Magnoliopsida, 23 families are represented by a single species, while in Liliopsida, 7 families are symbolized by a single species. Vegetation analysis shows that herbs are represented by 133 taxa, shrubs by 23 and trees by 48 taxa. Dichotomous bracketed keys to the families, genera, species and varieties are provided for easy identification of the taxa. Each taxon is supplemented by updated nomenclature, habit and representative specimen. Bangladesh J. Plant Taxon. 27(2): 293-322, 2020 (December)

This study provides bibliographical note on the syntaxonomy of the vegetation of Tlemcen, Hafir, Moutas of North-western Algeria, including the associations and alliances of the different higher units found in the Hafir forest and the Moutas Reserve. In this work, we observed modifications of forest and pre-forest structures according to bioclimatic variations. However, in this region, the xericity of the climate is not the only factor destroying the plant cover, anthropization is also a degradation factor. While being aware of the negative consequences, man, through their abusive cultivation, illegal logging, overgrazing, urbanization, the depletion of natural resources;, inhibits the evolution of vegetation, participates in the replacement of a rich plant cover by another and more xerophytic plant cover with thorny and/or toxic feature. The landscape is dominated, for the most part, by open and degraded formations based on therophytes and chamaephytes, linked to Rosmarinetea and Cisto-Lavanduletea. The tree structures in Hafir and the Moutas reserve, still occupy only minimal areas subject to the destructive actions of man and his flock. These formations are still linked to the Quercetea ilicis. These ecosystems are marked by a regressive evolution (forest, pre-forest, scrub, scrubland and therophytization). Bangladesh J.

The Dipterocarpaceae is the only timber-producing taxon in the angiosperm, and it is the most important source of timber in Southeast Asia (Soerianegara and Lemmens, 1993). Dipterocarp trees are influential in their structure and function (Brearley et al., 2017). Dipterocarps are highly productive (Banin et al., 2014) and important storage of above-ground carbon (Slik et al., 2013). The taxonomy of several genera of Dipterocarpaceae is relatively well defined but the genus Shorea remains problematic and has proved most controversial (Maury-Lechon and Curtet, 1998). In the Philippines, there are about 45 species of dipterocarps distributed in 6 genera (Rojo and Aragones Jr, 1997). It has been well-studied but the identities of individual species remain ambiguous (Rojo and Aragones Jr, 1997). In Mindanao, a species locally known as "malacayan blanco" was originally described by Foxworthy (1938) from Zamboanga Province, and named as Pentacme mindanensis. Based on Foxworthy’s description, P. mindanensis has resemblance with Shorea contorta but differs in its large leaves and large fruits. However, Ashton (1978) treated P. mindanensis as a synonym of S. contorta, an island endemic, commonest, and widely distributed dipterocarp species (Foxworthy, 1938; Rojo and Aragones Jr, 1997). Furthermore, there are few detailed morphological, anatomical (Pulan and Buot, 2014), and molecular (Umali, 2016; Villarin et al., 2016) studies on S. contorta. Until recently, Umali (2016) confirmed through molecular characterization that S. contorta and P. mindanensis are two different species. Generally, the recent advancement in biosystematics using DNA sequences has provided evidences to the resolution in the correct classification of many dubious taxon. However, doubts to the reliability of the system arises because many species with very obvious morphological dissimilarities were merged and considered into one species, for instance, Ficus latsonii Elmer and Ficus variegata Blume of Moraceae, the former having a distinct brown-orange trunk while the later has whitish. Also, for the species Melicope monophylla Merr. and Melicope triphylla (Lam.) Merr. of Rutaceae, the former with simple leaf while the latter having a compound one. In this present study, our longstanding knowledge on these species aside from differing fruits and leaf sizes was based mainly on the color of the inner bark with P. mindanensis having a cream-yellow while S. contorta has white. Thus, in support to the work of Umali (2016), we aim to provide more striking differences via leaf morphometrics. Leaf morphometrics has proved to be effective in resolving taxonomic problems and discriminating species.

The systematic relationships of Krameriaceae have changed considerably. The phylotranscriptomic data sets provide highly informative data for resolving deeper‐level phylogenetic relationships. The phylotranscriptomic analyses to infer evolutionary relationships of Krameriaceae in the order Zygophyllales using the Minimum Evolution, Maximum Parsimony and Maximum Likelihood methods recovered similar topology and taxon proximity. Under the Zygophyllales clade, Krameria lanceolata Torr. of the family Krameriaceae nested with Tribulus eichlerianus K.L. Wilson and Larrea tridentata (Sesse & Moc. ex DC.) Coville belonging to the family Zygophyllaceae with strong nodal support. The phylotranscriptomic analyses suggest that the family Krameriaceae is sister to Zygophyllaceae. Bangladesh J. Plant Taxon. 27(2): 427-433, 2020 (December)
