(Asteraceae) in Turkey <p>In this paper, the palynomorphology of 17 taxa of section <em>Cheirolepis</em> in Turkey,&nbsp;were investigated by light (LM) and scanning electron microscope (SEM). Detailed&nbsp;descriptions of the pollen grains were given for each taxon and a well-resolved&nbsp;dendrogram was generated through numerical analysis of palynological diagnostic&nbsp;features. The pollen grains were found to be radially symmetric, isopolar, and generally&nbsp;3-zonocolporate, with the exception of <em>C. derderiifolia</em>, <em>C. kotschyi</em> var. <em>floccosa</em>, and <em>C.&nbsp;saligna</em>, which were also 4-zonocolporate. The shape of the pollen grains were prolatespheroidal,&nbsp;with the polar axes of 32.76–46.26 μm and equatorial axes of 31.86–45.82&nbsp;μm. The sculpturing of the pollen grains was generally scabrate-perforate or rarely&nbsp;microechinate-perforate. The spines were conical with a changing base length. The length&nbsp;and the width of the spines varied between 0.48 and 2.28 μm and 0.4 and 3.39 μm,&nbsp;respectively. The number of perforations at the base of the spines ranged in two or more<br>rows and they varied between 5 and 30. The number of spines was 16–70 in 10 μm2. The&nbsp;results of this study showed that the polar axes, equatorial axes, aperture type, pollen&nbsp;shape, spine length, perforation number, and number of spines in 10 μm2 are essential for&nbsp;distinguishing the studied taxa. The taxa were grouped by clustering analysis of selected&nbsp;pollen characters using the UPGMA method.</p> Burcu Yilmaz Çitak, Hüseyin Dural, Tuna Uysal, Nur Münevver Pinar ##submission.copyrightStatement## Mon, 23 Dec 2019 12:01:08 +0000 New records of three species and a genus of angiosperms for Bangladesh <p>Three species viz., <em>Cayratia maritima</em> Jackes of family Vitaceae Juss., <em>Leptadenia&nbsp;reticulata</em> (Retz.)

Results revealed pollen grains of <em>Artemisia</em> species with tricolporate shape, and characterized by&nbsp;globular symmetry (ellipsoid ball shaped from equatorial side and three lobed rounds from polar view) with&nbsp;few exceptions. Additionally, the pollens are marked with reduced spinules on their surfaces which are&nbsp;diagnostic character for the genus <em>Artemisia</em>. In this study, seven micromorphological characters of pollen&nbsp;grains of 15 <em>Artemisia</em> species <em>viz.</em> shape of pollen, arrangement of spinules, exine sculpture, spinules base,&nbsp;equatorial width and polar length, were employed to construct a dendrogram following the consequential&nbsp;cluster analyses. In the dentrogram, four groups within the studied Artemisia species have been recognized.&nbsp;The pollen morphology of <em>Artemisia</em> could be a good taxonomic marker to cope with its taxonomic&nbsp;delimitations in combination with other floral and molecular attributes.</p> Adil Hussain, Daniel Potter, Muhammad Qasim Hayat, Sumaira Sahreen, Syed Ali Imran Bokhari ##submission.copyrightStatement## Mon, 23 Dec 2019 12:37:39 +0000 Morphological and molecular identification of ten plant pathogenic fungi <p>Ten pathogenic fungi of Deuteromycetes were isolated from seven angiospermic&nbsp;hosts such as pointed gourd, tomato, rice, wheat, maize, chickpea and jute.&nbsp;Morphological characterization and molecular analyses were performed for accurate&nbsp;identification of the isolated pathogenic fungi.

The diversity center of this species is in the Fertile&nbsp;Crescent and in central Asia and could also be found in many places in Iran. In this&nbsp;experiment, 359 accessions provided by National Plant Gene Bank of Iran (NPGBI) were&nbsp;used. Based on the geographical distribution, the highest distribution of <em>A. cylindrica</em> is&nbsp;found in North, West and North-West regions of Iran. The data on the distribution of <em>A.&nbsp;cylindrica</em> showed that its distribution centers in Iran are more than those reported in the&nbsp;previous studies. Chromosome counting showed that all <em>A. cylindrica</em> accessions are&nbsp;tetraploid (2n=4x=28). Results of factor analysis for nine morphological chromosome&nbsp;traits showed that karyotypic variation within accessions are related to the length of&nbsp;chromosomes and there is difference between the accessions for their total chromosome&nbsp;length, but the karyotype of different accessions are almost the same for the symmetry.&nbsp;Low coefficient of variation in morphological traits as well as symmetric karyotypes of&nbsp;<em>A. cylindrica</em> species observed in this study could lead us to predict that <em>A. cylindrica&nbsp;</em>could be a recently evolved species among the remote relatives of bread wheat.</p> Behnam Bakhshi, Mohammad Jaffar Aghaei, Eissa Zarifi, Mohammad Reza Bihamta, Ehsan Mohseni Fard, Mohammad Reza Naroui Rad ##submission.copyrightStatement## Mon, 23 Dec 2019 13:35:03 +0000 Three new species records of the genus <i>Pinalia</i> Lindl.

(Convolvulaceae) grown in Asir region, Saudi Arabia <p>DNA barcoding and morpho-anatomical characters of two forms of <em>Convolvulus&nbsp;arvensis</em> L. growing in Asir region, Saudi Arabia were studied. We applied three&nbsp;molecular markers, ITS, rbcL and matK for phylogenetic reconstruction in combination&nbsp;with 24 morpho-anatomical characters to provide proposal for the recognition of its&nbsp;population under two forms. Plant samples were collected from ten various populations&nbsp;of <em>C. arvensis</em> supposed to be of two different forms, and finally these have been found to&nbsp;be of two new forms (small leaf) and form (large leaf) for the flora of Saudi Arabia.&nbsp;TWINSPAN results showed that there was negative group with twenty one objects&nbsp;including stem length, stem thickness, seed shapes, petiole length, leaf apex, leaf length,&nbsp;petal circumference, leaf width, capsule length, capsule width, stamen length, anther&nbsp;width, anther length, carpel length, venations type, pollen grains shape, T.S of stem, root&nbsp;and leaf, stigma shape and anther base surface and positive group including hairs,&nbsp;stomata and anther shape. Dendrogram upon morpho-anatomical characters resolved two&nbsp;main clusters, one cluster of form (large leaf) and the other of form (small leaf).&nbsp;Amplified gene region for the form (small leaf)-<em>rbc</em>L showed 100% identity with <em>C.&nbsp;lineatus</em>; form (small leaf)-<em>mat</em>K and form (large leaf)-<em>mat</em>K had 99% identity with&nbsp;<em>Calystegia sepium</em> (L.) R. Br. Form of (small leaf)–ITS had 100% identity with that of <em>C.&nbsp;arvensis</em>; form (large leaf)-<em>rbc</em>L had 100% identity with those of <em>C. arvensis</em> and <em>C.&nbsp;lineatus</em>. Form (large leaf)–ITS had 99% identity with that of <em>C. arvensis</em>. The results of&nbsp;molecular phylogenetic analyses based on certain morphological and rbcL data support&nbsp;two main clusters within <em>C. arvensis</em> which is consistent with two forms, form (small&nbsp;leaf) and form (large leaf).</p> Mahmoud Moustafa, Saad Alamri, Ali Shati, Mohmed Al-Kahtani, Sulaiman Alrumman, Abdelraheem Tawfek ##submission.copyrightStatement## Mon, 23 Dec 2019 14:10:06 +0000 Morphological and anatomical investigation among six variants of <i>Canna indica</i> L. <p>The present study explores detailed morphological and anatomical features of six&nbsp;variants of <em>Canna indica</em> L. Noticeable variations have been recorded in the morphology&nbsp;of six variants of <em>C. indica</em> especially on the basis of their different colours of leaves,&nbsp;flowers, staminodes and fruits. Root, stem and leaf anatomy of <em>C. indica</em> revealed little&nbsp;variation among the variants employed in the study. Phloem is 5-6 layered in the variant&nbsp;2 (small red), 4-5 layered in the variant 4 (orange), and 3-4 layered in the remaining&nbsp;variants. The variant 4 (orange) can be distinguished from other five variants&nbsp;anatomically, by presence of 5-7 layers of schlerenchymatous tissue, and morphologically&nbsp;by its green pseudostem, ovate to obovate leaves, orange flowers, green bracts&nbsp;with maroon edges and orange-red staminodes. However, based on morphological and&nbsp;anatomical discrepancies the variants of <em>Canna indica</em> cannot be assigned to discrete&nbsp;taxonomic variety.</p> Nahid Sultana, Sabiha Sultana Akhi, Md.

Ethnomedicinal data&nbsp;were collected using semi-structured interviews with key informants during June 2017 to&nbsp;July 2018 followed by field interviews, plant interviews, checklist interviews and group&nbsp;discussion techniques. A total of 92 ethnomedicinal plant species under 46 families have&nbsp;been documented. These species were used to treat 55 ailments through 200 formularies.&nbsp;Herbs are the most common medicinal plants in the study area followed by trees, shrubs&nbsp;and climbers. Leaf is mostly used for the preparation of herbal medicine. Among the total&nbsp;92 ethnomedicinal plants, 11 species have been used for diabetes management by the&nbsp;community people. Disease category diabetes showed maximum factor informant<br>consensus value. Most cited ethnomedicinal plant species for the diabetes management&nbsp;are <em>Gynura nepalensis</em> DC., <em>Coccinia grandis</em> L. Voigt, <em>Aloe vera</em> (L.) Burm. f., <em>Syzygium&nbsp;cumini</em> (L.) Skeels, <em>Swietenia mahagoni</em> (L.) Jacq., <em>Momordica dioica</em> Roxb. <em>ex.</em> Willd.,&nbsp;<em>Catharanthus roseus</em> (L.) G. Don, <em>Streblus asper</em> Lour., <em>Bryophyllum pinnatum</em> (Lamk.)&nbsp;Oken, <em>Tamarindus indica</em> L. and <em>Scoparia dulcis</em> L. The results in the present study for&nbsp;diabetes management were very preliminary and based on which sound conclusion was&nbsp;not possible. Further ethnopharmacological study is very essential on such species to&nbsp;validate their efficacy in the management of diabetes. Our findings also provide baseline&nbsp;data to establish a connection between the traditional users of medicinal plants and&nbsp;scientific communities, which can be substantial in novel drug discovery. Furthermore,&nbsp;ethnomedicinal data is of significant value for conservation managers and policy makers&nbsp;for sustainable management of ethnomedicinal plant species, which are under threat due&nbsp;to rapid urbanization.</p> Mohammad Zashim Uddin, Farhana Yesmin Mitu, Atiya Begum Rifat, Abdullah Al-Kaium ##submission.copyrightStatement## Mon, 23 Dec 2019 14:40:40 +0000 Morpho-molecular characterization of <i>Ceratobasidium</i> sp.: A mycorrhizal fungi isolated from a rare epiphytic orchid <i>Gastrochilus calceolaris</i> (J. E. Sm.) D. Don <p>A mycorrhizal fungus, <em>Ceratobasidium</em> sp. GC (NCBI Gene Bank Accession no&nbsp;GQ369961) associated with the roots of an epiphytic orchid <em>Gastrochilus calceolaris</em> was&nbsp;investigated by cultural morphology, microscopic features and molecular analysis of&nbsp;Internal Transcribed Spacer (ITS) regions sequences of nuclear ribosomal DNA. The&nbsp;colony appearance of the fungal endophyte was fluffy growth pattern and the colour of&nbsp;the young colony was milky white on both surfaces that turned in to brown at maturity on&nbsp;the upper surface and deep brown on reverse surface. The microscopic features of the&nbsp;fungus i.e. hyphal diameter, multi-nucleate vegetative cells, right angle branching pattern&nbsp;with slight constriction at branching point and a dolipore septum near the branching point&nbsp;were observed. All the characters corroborated the identity with anamorphic <em>Rhizoctonia&nbsp;</em>like fungi. The ITS regions sequences of nrDNA and phylogenetic analysis based on the&nbsp;neighbor-joining method showed clustered with <em>Rhizoctonia</em> like fungi, and the&nbsp;maximum identity (98.28%) with <em>Ceratobasidium</em> RR and <em>Ceratobasidium</em> FPUB&nbsp;isolated from <em>Rhynchostylis retusa</em> and <em>Dactylorrhiza hetagera</em>, respectively.
