A face-to-face two-part questionnaire survey was conducted with 82 local&nbsp;people. Identification of 29 taxa belonging to 18 families has been confirmed and their&nbsp;medicinal uses have been recorded. In addition, the usage patterns of plant parts and<br>purposes are recognized. Plants are mostly used in the treatment of cold and flu, stomach&nbsp;disorders, gynecological, cardiovascular, and respiratory diseases. The highest use value&nbsp;(UV) was recorded for Rosa canina (0.54) and Mentha longifolia subsp. longifolia (0.46)&nbsp;and the highest Informants Consensus Factor (FIC) was cited for cold and flu (0.83)&nbsp;followed by stomach disorders (0.75). New information for folklore medicines have been collected from the study area.</p> Mustafa Karaköse Sefa Akbulut Zafer Cemal Özkan ##submission.copyrightStatement## 2019-06-25 2019-06-25 26 1 29 37 10.3329/bjpt.v26i1.41914 Molecular characterization and new reports of two green algae from Bangladesh <p>This communication portrays the molecular characterization and confirms the new&nbsp;reports of two fresh water green algae namely, <em>Pithophora polymorpha</em> Wittrock and&nbsp;<em>Spirogyra maxima</em> (Hassall) Wittrock from Bangladesh. The samples of these algal&nbsp;species were cultured and partial 18S rDNA was sequenced and analysed for their&nbsp;molecular identification. It was found that the primers reported here could sufficiently&nbsp;identify these algae as <em>P. polymorpha</em> and <em>S. maxima</em>. Furthermore, the Neighbour joining (NJ) tree generated from 18s rDNA sequences suggested that <em>Spirogyra maxima</em>&nbsp;of Bangladesh is distantly related to the cluster of <em>S. juergensii</em> and <em>S. platensis</em>.&nbsp;<em>Pithophora polymorpha</em> along with <em>P. roettleri</em>, <em>P. sano</em> and <em>Pithophora</em> sp. seems to&nbsp;form a strongly supported monophyletic group. The alga AP1 clusters with <em>Pithophora</em>&nbsp;and the alga AS1 clusters with <em>Spirogyra</em>. This study is the first-time report of molecular&nbsp;identification of Bangladeshi algae and a landmark towards the future exploration of the<br>algal biodiversity of Bangladesh.</p> Md.

(Amaryllidaceae) taxa in Turkey <p>The pollen morphology of 10 <em>Allium</em> L. taxa, 6 of which are endemic to Turkey,&nbsp;were investigated in detail by light and scanning electron microscopy. According to LM&nbsp;and SEM, the pollen grains of genera were monad, monosulcate percolate, heteropolar&nbsp;with bilateral symmetry, 25.30 to 53,85 µm long axis (LA) and 17.55 to 36.86 µm short&nbsp;axis (SA), the form was prolate (mean of LA/SA ratio 1.30 to 1.70 and in polar view&nbsp;boat-shaped. Three types of ornamentation were determined. Striate-rugulate-perforate&nbsp;type in <em>Allium longisepalum,</em> <em>A. oreophilum</em>, <em>A. anacoleum</em>, <em>A. microspathum</em>, <em>A.</em><br><em>shirnakiense</em>, <em>A. purpureoviride</em> and <em>A. armenum</em>, Rugulate–perforate type in <em>A.&nbsp;pervariense</em> and <em>A. gabardagense</em> and Rugulate–reticulate-perforate type in <em>A.&nbsp;arlgirdense</em>. Sulcus membrane ornamentations were rugulate or psilate. The sulcus&nbsp;extends from the distal to proximal ends in <em>A. anacoleum</em>, <em>A. arlgirdense</em> and <em>A.&nbsp;pervariense</em>. The present study on some Turkish species of <em>Allium</em> showed that several&nbsp;morphological pollen characters may possess taxonomical value.</p> Birol Başer Mehmet Firat Riza Binzet ##submission.copyrightStatement## 2019-06-25 2019-06-25 26 1 47 55 10.3329/bjpt.v26i1.41916 Morphoanatomical profile of five species of Piper L. from Bangladesh and its taxonomic significance <p>The present study explores detailed morphoanatomical features of five species of&nbsp;<em>Piper</em> L., viz. <em>P. betle</em> L., <em>P. longum</em> L., <em>P. nigrum</em> L., <em>P. retrofractum</em> Vahl and <em>P.&nbsp;sylvaticum</em> Roxb. Each species is supplemented by detailed updated nomenclature,&nbsp;vernacular names, diagnostic characters, phenology, ecology and representative&nbsp;specimens. Maximum number of cortical and medullary vascular bundles have been&nbsp;observed in <em>P. nigrum</em> and <em>P. retrofractum</em>, respectively. In contrast, minimum number of&nbsp;cortical and medullary vascular bundles have been found in <em>P. sylvaticum</em>. Glandular<br>trichomes are found on the midrib of <em>P. betle</em>, <em>P. longum</em>, and <em>P. sylvaticum</em>, whereas&nbsp;trichomes are lacking in <em>P. nigrum</em> and <em>P. retrofractum</em>. The highest number of collateral&nbsp;vascular bundles have been found in <em>P. retrofractum</em> followed by <em>P. nigrum</em>, while <em>P.&nbsp;betle</em> and <em>P. longum</em> contain single collateral vascular bundle. <em>P. betle</em> can easily be&nbsp;distinguished from other species by its oval stem, non-glandular multicellular trichome&nbsp;with pointed tip, and presence of idioblasts and oil droplets. <em>P. longum</em> is distinct from&nbsp;remaining species by its diacytic stomata. Keys to the species based on morphological&nbsp;and anatomical characters are provided for easy identification of the studied species.</p> Kishwar Jahan Shethi Parveen Rashid Momtaz Begum M.

(Boraginaceae) from Turkey <p>Micromorphology and anatomy of six <em>Onosma</em> L. species, viz. <em>O. argentata</em> Hub.-Mor., <em>O. neglecta</em> Riedl, <em>O. proballanthera</em> Rech. f., <em>O. rechingeri</em> Riedl, <em>O. sericea&nbsp;</em>Willd. and <em>O. stenoloba</em> Hausskn. ex Riedl from Turky were investigated. Stem anatomy&nbsp;revealed that cuticle layer ranged from 0.6 µm in O. argentata to 1.7 µm in <em>O.&nbsp;proballanthera</em>. Parenchymatous cells of <em>O. neglecta</em> and <em>O. stenoloba</em> possessed more&nbsp;intense starch than the other species studied. In leaf anatomy, the longest palisade&nbsp;parenchyma was found in <em>O. neglecta</em>, while the smallest was noted in <em>O. argentata</em>.&nbsp;Mesophyll structure of <em>O. argentata</em>, <em>O. sericea</em> and <em>O. rechingeri</em> was equifacial&nbsp;(isobilateral), while <em>O. neglecta</em>, <em>O. proballanthera</em> and <em>O. stenoloba</em> presented bifacial&nbsp;(dorsiventral) structure. Rugose nutlet ornamentation was observed in <em>O. argentata</em>, <em>O.&nbsp;neglecta</em> and <em>O. sericea</em>, whereas reticulate type was found in <em>O. proballanthera</em>, <em>O.&nbsp;rechingeri</em> and <em>O. stenoloba</em>. <em>Onosma stenoloba</em> could easily be distinguished from other&nbsp;species by its aesterotrichous indumentum, and in contrary, other species possessed&nbsp;haplotrichous type of indumentum. Micromorphological features of nutlet surface,&nbsp;anatomical features of epidermal surface (trichomes and stomata), and lamina mesophyll&nbsp;structure (dorsiventral and isobilateral) could be useful in solving taxonomic problem of&nbsp;the genus.</p> Selami Selvi Ridvan Polat Ebru Yuce Babacan M.

The&nbsp;treatment of CVD by using modern medicines is very expensive. The present article&nbsp;mainly focuses the ethnomedicinal plants used by the local people for the prevention of&nbsp;cardiovascular diseases in Bangladesh. Information on the ethnomedicinal uses of plants&nbsp;was collected using semi-structured interviews with key informants during the year of<br>2017 and 2018. Group discussion with local people was also conducted for the promotion&nbsp;of data collection. A total of 41 medicinal plant species was recorded for the prevention&nbsp;of cardiovascular diseases. These species belong to 30 families. The most frequently used&nbsp;medicinal plant species for the prevention of cardiovascular diseases were <em>Terminalia&nbsp;arjuna</em> (Roxb. <em>ex</em> DC.) Wight &amp; Arn.,<em> Terminalia bellirica</em> (Gaertn.) Roxb., <em>Terminalia</em><br><em>chebula</em> Retz., <em>Allium sativum</em> L., <em>Tamarindus indica</em> L. and <em>Alternanthera sessilis</em> (L.) R.&nbsp;Br. <em>ex</em> Roem. Informant consensus factor (Fic) has been calculated to determine the&nbsp;agreement of local people in the use of medicinal plants for the CVD. Among the&nbsp;ailments categories high Fic value was found in case of antioxidant followed by&nbsp;heartache, high blood pressure and blood purifier. Comparing with previous research&nbsp;<em>Hylocereus undatus</em> (Haw.) Briton and Rose, <em>Alternanthera paronychioides</em> Klotzsch <em>ex&nbsp;</em>Koch and <em>Lactuca sativa</em> L. were seem to be newly reported medicinal plants for the&nbsp;prevention of cardiovascular diseases in Bangladesh. The plant species with high&nbsp;citation, Fic and Fl values can be subjected to phytochemical investigation to&nbsp;find new class of active compounds for the treatment of cardiovascular diseases.&nbsp;The findings of the present study are very preliminary. Further long term studies&nbsp;are needed to validate the ethnomedicinal plants used by the local people for the&nbsp;prevention of cardiovascular diseases in Bangladesh.</p> Mohammad Zashim Uddin Atiya Begum Rifat Farhana Yesmin Mitu Tahmina Haque ##submission.copyrightStatement## 2019-06-25 2019-06-25 26 1 83 95 10.3329/bjpt.v26i1.41920 Anatomical investigation of four taxa of Scutellaria albida L. (Lamiaceae) <p>The root, trunk and leaf anatomy of four taxa of Scutellaria albida namely, S. albida&nbsp;subsp. albida, S. albida subsp. velenovskyi, S. albida subsp. colchica and S. albida subsp.&nbsp;condensata were examined. The aim is to determine whether these characters can be used&nbsp;for systematic purposes. The roots displays a typical stele structure in all studied taxa.&nbsp;But their number of pith rays are different in each taxa. The stems of S. albida taxa have&nbsp;square like transection, collateral vascular bundles, parenchymatous pith and show 1-2&nbsp;layered epidermis coated with thick cuticle. S. albida subsp. condensata has papillate&nbsp;epicuticular wax on its stem cuticle layer. In all taxa angular collenchyma, and cambium&nbsp;forming phloem outward and xylem inward are observed. The leaves are hypostomatic,&nbsp;have single rowed epidermis coated with thick cuticle and show dorsiventral mesophyll&nbsp;in all studied taxa. S. albida subsp. velenovskyi has echinate epicuticular wax on its leaf&nbsp;cuticle layer, but the others have smooth cuticle layer. The midrib shows one collateral&nbsp;bundles in all taxa but the shape of median veins of the leaf blade show variation in each&nbsp;taxa. Some of the anatomical characters viz. the number of pith rays of roots, the number&nbsp;of palisade parenchyma layer, plant cuticles covered by wax, the shape of median veins&nbsp;of the leaf blade and stomata index, provide information of taxonomical significance for&nbsp;these taxa.</p> Ersin Minareci Sinem Pekönür Canan Özdemir Mehmet Çiçek Okan Kocabaş ##submission.copyrightStatement## 2019-06-25 2019-06-25 26 1 97 106 10.3329/bjpt.v26i1.41921 Comparative chloroplast genomic analyses revealed extensive genomic arrangement in some core and non-core caryophyllales <p>The order Caryophyllales exhibit diverse diversity in morphology to molecules,&nbsp;which leads to taxonomic complexities in circumscribing especially to its families. The&nbsp;comparative analysis of the available chloroplast genome to detect pattern of genomic&nbsp;arrangement and variation is lacking; hence, the alignment pattern and genomic&nbsp;rearrangement across the Caryophyllales were detected, and the phylogenetic relationship&nbsp;among the families of the Caryophyllales based on maximum cp genes were inferred. The&nbsp;comparison of the Caryophyllales cp genomes based on representatives of 10 families&nbsp;with <em>Taxillus chinensis</em> as reference genome revealed that coding region were more&nbsp;conserved than the non-coding region; however, clpP, rpl16 and ycf15 were the most&nbsp;divergent coding region among all taxa. Further, the genomic rearrangement occurred in&nbsp;gene organization of the taxa among different families of Caryophyllales, the extensive&nbsp;rearrangement were observed in Amaranthaceae, Caryophyllaceae, Chenopodiaceae,<br>Droseraceae and Cactaceae.</p> M.
