The most important reason of the species diversity in Turkey is its location and geomorphological structure which increase climatic effects and seperate Turkey into different phytogeographic regions. Furthermore, hybridization behaviours which frequently observed between oak species, genetic drift, gene flow and ecological factors cause morphological variations in the plants species. All of these factors make it difficult to define the species concept for plant groups like oaks. Therefore, the region covering 18S rRNA gene/ ITS1/ 5.8S rRNA gene/ ITS2/ 25S rRNA gene and secondly intergenic spacer (IGS)/ 5S rRNA gene for barcoding were obtained from genbank and used as a useful tool for the determination and solution of the phylogenetic relations of taxonomically problematic species, also these barcoding regions were compared with each other according to species recognition ability for oak species. As a result, it can be stated that both barcoding regions have high variable sites based on sequence information to identify the species and evaluate relationships of species studied. \u0000Bangladesh J.

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. \u0000Bangladesh J.

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.

Only 11 Leucoagaricus species have been reported from Pakistan so far (Ahmad et al., 1997; Qasim et al., 2015; Ge et al., 2017; Hussain et al., 2018; Usman and Khalid, 2018; Ullah et al., 2020). Leucoagaricus is characterized by small to medium, fleshy or thin basidiomata, ranging in stature from slender to sturdy; a pileus surface that is radially fibrillose, floccose, squamulose to fibrillose-scaly or granulose (rarely); entire or very short striate margins; a central, equal to bulbous stipe with a membranous, sometimes moveable annulus; metachromatic basidiospores generally lack a welldefined germ pore and are thin-walled and smooth; and the pileipellis is either a trichoderm or a cutis of repent and radially arranged hyphae lacking sphaerocysts. Pleurocystidia are absent in most species. Clamp connections are absent (Singer 1986; Vellinga 2001).

This research is an effort to establish the fungal diversity of this forest. During field survey in 2019 for the collection of macrofungi to explore the diversity of these fungi from Changa Manga. A number of basidiomata of Leucoagaricus were collected. Field notes were recorded and the samples were air dried and preserved for future analysis. Macroscopic descriptions were based on the fresh material. Significant characters involve size, shape and color of the pileus; attachment and color of lamellae; presence of annulus on stipe. Color codes were given using Munsell (1975) color system. For micro-morphology, dried samples were examined using standard microscopic techniques. Different chemicals were used as mounting media according to requirements. For rehydration, 5% KOH was used, and for staining the walls of hyaline hyphae, Congo red was used.

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). \u0000Bangladesh J.

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.","PeriodicalId":55590,"journal":{"name":"Bangladesh Journal of Plant Taxonomy","volume":null,"pages":null},"PeriodicalIF":0.9,"publicationDate":"2020-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44802257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
