(Bryophyta: Pottiaceae) against some Pathogenic Bacteria Anshul Bishnoi, Vanshika Singh, Vinay Sharma and Afroz Alam* Department of Bioscience and Biotechnology, Banasthali University, Tonk -304 022 (Rajasthan), India *Corresponding author: Dr. Afroz Alam Phone: +919785453594 Manuscript received : 19.10.15 Manuscript accepted: 22.11.15 Abstract In recent years bryophytes have emerged as potential plants for many bioactive phytochemicals with antimicrobial efficacies. In present study antibacterial activity of Anoectangium clarum Mitt. has been assessed using various extracts. For this assessment agar diffusion method is used against selected pathogenic fungus. Tetracycline is used as positive control. The ethanolic extract of moss exhibited a superior effect than the extract prepared in methanol. The utmost effect was observed against Escherichia coli followed by Salmonella typhimurium and Bacillus subtilis. This study projects Anoectangium clarum as an eco-friendly antibacterial agent. Keywords: Anoectangium clarum, antibacterial activity, extract, moss, well diffusion method. 650 SMU Medical Journal, Volume – 3, No. – 1, January, 2016 Introduction Plants are treasured source of natural products for upholding normal health of human beings. Conventional therapeutic systems of Ayurveda, Unani and Sidha are the prevalent verification of their use in therapy. In the last few decades, with more rigorous researches for therapies based on natural systems, plants are used extensively to cure different diseases especially dermal ailments [1]. The search for unexplored plants or plant group with substantial antimicrobial action has attained massive importance these days, due to a growing concern about the attainment of antibiotic- resistance by the pathogenic microorganism.

The incomplete preservation and lack of key characters that could define the position of an ancient moss in modern classification remain the problem. Carboniferous records are still impossible to refer to any of the modern moss taxa. Numerous Permian protosphagnalean mosses possess traits that are absent in any extant group and they are therefore treated here as an extinct lineage, whose descendants, if any remain, cannot be recognized among contemporary taxa. Non-protosphagnalean Permian mosses were also fairly diverse, representing morphotypes comparable with Dicranidae and acrocarpous Bryidae, although unequivocal representatives of these subclasses are known only since Cretaceous and Jurassic. Even though Sphagnales is one of two oldest lineages separated from the main trunk of moss phylogenetic tree, it appears in fossil state regularly only since Late Cretaceous, ca.

  • SPECIES FACT SHEET Ryszard's Racomitrium Moss
    SPECIES FACT SHEET Common Name: Ryszard's racomitrium moss Scientific Name: Codriophorus ryszardii Recent synonyms: Racomitrium ryszardii. All reports of Racomitrium aquaticum (= Codriophorus aquaticus) from North America refer to Codriophorus ryszardii. Division: Bryophyta Class: Bryopsida Order: Grimmiales Family: Grimmiaceae Taxonomic Note: All North American records for Codriophorus aquaticus (= Racomitrium aquaticum) have been renamed Codriophorus ryszardii (= Racomitrium ryszardii), and C. aquaticum has been restricted to the Old World (Benarek-Ochyra 2000; Ochyra and Benarek-Ochyra 2004a). Nomenclature used in this species fact sheet follows the conspectus for the Racomitroideae proposed for use in the Bryophyte Flora of North America (Ochyra and Benarek-Ochyra 2004b). Technical Description: Plants trailing or to erect, 1-10 cm long, branched irregularly. Leaves green, yellow-green to blackish below, linear-lanceolate, straight or curved at shoot tips, imbricate when dry, 2- 4 mm long, 0.4-1 mm wide, tapered to a rounded, roughened tip; margins entire, recurved, lacking row of large thin-walled cells at base; costa forming prominent keel at back of leaf, extending nearly to leaf tip and never forming an awn; leaf cells multipapillose, the cell walls sinuose-wavy. Setae 4-8 mm long, twisted clockwise when dry. Capsules 2-3 mm long, cylindrical. Peristome teeth 0.6-0.8 mm long. Distinctive characters: (1) Leaf cells multipapillose, (2) leaves imbricate, strongly keeled and consistently awnless, (3) leaves bright green to yellow-green, (4) peristome 1 mm long, (5) moist shaded rock substrate. Similar species: Codriophorus varius (= Racomitrium varium) is very similar, but (1) usually at least some of its leaves have distinct awns, (2) its peristome teeth are an astonishing 1-1.7 mm long, forming a tepee-shaped cone that is frequently broken, and (3) its habitat on rocks, logs and soil is usually drier than that of C.

  • Globally Widespread Bryophytes, but Rare in Europe
    Portugaliae Acta Biol. 20: 11-24. Lisboa, 2002 GLOBALLY WIDESPREAD BRYOPHYTES, BUT RARE IN EUROPE Tomas Hallingbäck Swedish Threatened Species Unit, P.O. Box 7007, SE-75007 Uppsala, Sweden. [email protected] Hallingbäck, T. (2002). Globally widespread bryophytes, but rare in Europe. Portugaliae Acta Biol. 20: 11-24. The need to save not only globally threatened species, but also regionally rare and declining species in Europe is discussed. One rationale of red-listing species regionally is to be preventive and to counteract the local species extinction process. There is also a value in conserving populations at the edge of their geographical range and this is discussed in terms of genetic variation. Another reason is the political willingness of acting locally rather than globally. Among the rare and non-endemic species in Europe, some are rare and threatened both in Europe and elsewhere, others are more common outside Europe and a third group is locally common within Europe but rare in the major part. How much conservation effort should be put on these three European non-endemic species groups is briefly discussed, as well as why bryophytes are threatened. A discussion is given, for example, of how a smaller total distribution range, decreasing density of localities, smaller sites, less substrate and lower habitat quality affect the survival of sensitive species. This is also compared with species that have either high or low dispersal capacity or different longevity of either vegetative parts or spores. Examples from Sweden are given. Key words: Bryophytes, rarity, Europe, dispersal capacity, Sweden. Hallingbäck, T. (2002).

The geographical range of the new species is restricted to the southern-temperate and southern-cool-temperate zones of Tasmania and New Zealand, with maximum occurrence on the South Island of the latter insular country. The species is described and illustrated and its distribution is mapped. The systematic position of B. seppeltii is revealed to be a sister to New Zealand B. allanfifei Bednarek-Ochyra & Ochyra by molecular evidence based on parsimony analysis of nuclear sequences. In some morphological and anatomical traits, B. seppeltii is similar to southern South American cool-temperate B. heterostichoides (Cardot) Bednarek-Ochyra & Ochyra but is distinct by its smooth laminal cells, strict hyaline leaf hair points, erect growth form, and very broadly recurved leaf margin in the distal portion.

Distributional patterns were 21 analysed using a geographic information system. Biogeographic patterns were determined 22 with a variety of multivariate statistics. 23 24 Results Plants have been recorded from throughout the Antarctic including all latitudes 25 between 60°S and 86°S. Species richness declines with latitude along the Antarctic 26 Peninsula, but there was no evidence for a similar cline in Victoria Land and the 27 Transantarctic mountains. MDS ordinations showed that the species composition of the 28 South Orkney, South Shetland Islands and the north western Antarctic Peninsula are very 29 similar to each other, as are the floras of different regions in continental Antarctica. However 30 they also suggest that the eastern Antarctic Peninsula flora is more similar to the flora of the 31 southern Antarctic Peninsula than to the continental flora (with which it has traditionally been 32 linked).

БОРОВИЧЕВ1,2, ВАДИМ А. БАКАЛИН3,4, АННА А. ВИЛЬНЕТ2 Abstract The genus Asterella P. Beauv. includes four species in Russia: A. leptophylla and A. cruciata are restricted to the southern flank of the Russian Far East and two others, A. saccata and A. lindenbergiana occur mostly in the subartcic zone of Asia and the northern part of European Russia. Asterella cruciata is recorded for the first time in Russia. The study of the ribosomal LSU (or 26S) gene and trnL-F cpDNA intron confirmed the placement of Asterella gracilis in the genus Mannia and revealed the close relationship of A. leptophylla and A. cruciata, and the rather unrelated position of A. saccata and A. lindenbergiana. The phylogenetic tree includes robustly supported terminal clades, however with only weak support for deeper nodes. In general, Asterella species and M. gracilis from Russia show low levels of infraspecific variation. An identification key and species descriptions based on Russian specimens are provided, along with details of specimens examined, ecology and diagnostic characters of species. Резюме Род Asterella P. Beauv. представлен в России четырьмя видами: A. leptophylla и A. cruciata ограничены в распространении югом российского Дальнего Востока, а два других вида, A. saccata и A. lindenbergiana, распространены преимущественно в субарктической Азии и северной части европейской России.

Tous droits réservés The genus Plagiochasma (Aytoniaceae, Marchantiopsida) in Thailand Sahut CHANTANAORRAPINT* & Kitichate SRIDITH Department of Biology, Faculty of Science, Prince of Songkla University, Hat Yai, Songkhla, 90112 Thailand Abstract – The genus Plagiochasma Lehm. et Lindenb. in Thailand is reviewed, based on herbarium specimens and especially on recently collections. The genus is reported for the first time from Thailand. Two species are recognized, namely P. appendiculatum Lehm. et Lindenb. and P. cordatum Lehm. et Lindenb. Descriptions, illustrations, and a key to species are provided. Aytoniaceae / complex thalloid liverworts / Marchantiopsida / Plagiochasma / Thailand INTRODUCTION Thailand is well-known as one of the richest areas in term of biodiversity. This area is located in both the Indo-Burmese and Sundaland hotspots (Myers et al., 2000), and includes areas identified as the overlapping zone of the Sino- Himalayan and Malesian floristic regions (Smitinand, 1989). The first report for liverworts in Thailand was made by Stephani (1902) who recorded seventeen species of liverworts from Koh Chang (Island), including four new species. During 1901-1904, Hosseus collected plant specimens from the northern part of the country, and reported five liverworts (Hosseus, 1911). Later, many contributions of Thai liverworts were received. In 2008, Lai et al. published an updated checklist of Thai liverworts and hornworts based on the literatures and their currently collections, including 376 species of liverworts. In recent years, some additions of interesting liverworts to Thailand have been reported (Kornochalert et al., 2010; He et al. 2012, 2013; Kornochalert et al., 2012; Wei & Zhu 2013; Sukkharak, 2013).

Brid. make it difficult to study. However, in Europe, there has been increasing interest in this species in the past few years, mostly as a result of the implementation of the Natura 2000 network. In Poland, B. viridis has only been reported in isolated studies that have been limited in terms of area and the number of participating workers. One of the Polish regions where B. viridis was recently recorded is the Bieszczady Mountains, but there have been no large-scale surveys of that region to date. The objective of the current work was to describe the B. viridis population in the Bieszczady Mountains in terms of its spatial distribution and abundance, investigate its selected microhabitat preferences, and evaluate the conservation status of this moss species within the Natura 2000 site Bieszczady PLC180001. The studied region encompassed 93,490.44 ha, including 69,056.23 ha of managed forests and 24,434.21 ha of forests belonging to the Bieszczady National Park.

  • GUIDE to the MOSSES of CENTRAL FLORIDA with an INTERACTIVE KEY by Frederick B
    Go to Index GUIDE TO THE MOSSES OF CENTRAL FLORIDA WITH AN INTERACTIVE KEY by Frederick B. Essig University of South Florida Herbarium Institute for Systematic Botany [Revised March 4, 2020] This guide has been prepared as an adjunct to the Atlas of Florida Plants. It includes an interactive key and illustrated species profile pages. The guide presently focuses on the common mosses of central Florida and includes 59 species, or for some entries just a genus. The guide is a work in progress, with the intention to gradually expand it to include less common species, as well as to expand the area of coverage from Central Florida to the entire state. It will therefore be periodically updated. The guide also includes an index, which includes all species reported as occurring in Florida, with the species included in the key set in bold face and larger type. The index also serves as a list of photo credits for the species included in the species profile pages. The key is in pdf format, with active links to move through the key and to the species profile pages. In the profile pages and the index, there are links to the appropriate pages in the Atlas. To make the guide as broadly useful as possible, simple botanical and/or English terminology has been used, rather than the specialized bryophyte terminology of technical keys. Corrections and suggestions will be greatly appreciated, and should be sent to Fred Essig at [email protected]. 1 Go to Index Interactive Key 1.
