A Revision of Schoenobryum (Cryphaeaceae, Bryopsida) in Africa1
Revision of Schoenobryum 147 Tropical Bryology 24: 147-159, 2003 A revision of Schoenobryum (Cryphaeaceae, Bryopsida) in Africa1 Brian J. O’Shea 141 Fawnbrake Avenue, London SE24 0BG, U.K. Abstract. The nine species and two varieties of Schoenobryum reported for Africa were investigated, and no characters were found that uniquely identified any of the taxa to be other than the pantropical Schoenobryum concavifolium. The following nine names become new synonyms of S. concavifolium: Cryphaea madagassa, C. subintegra, Acrocryphaea robusta, A. latifolia, A. subrobusta, A. tisserantii, A. latifolia var. microspora, A. plicatula and A. subintegra var. idanreense; a lectotype is selected for Acrocryphaea latifolia var. microspora P.de la Varde.

Natural Radioactive Element Content of the Old Crystalline Rocks in Southern Transdanubia (Sw Hungary)
Acta Mineralogica-Petrographica, Szeged, XL, 121-138, 1999 NATURAL RADIOACTIVE ELEMENT CONTENT OF THE OLD CRYSTALLINE ROCKS IN SOUTHERN TRANSDANUBIA (SW HUNGARY) E. PÁL MOLNÁR*, I. VADOS**, I. GERZSON**, B. KÓBOR* •Department of Mineralogy, Geochemistry and Pétrology, Attila József University "Mecsekérc Environment Protection Co. ABSTRACT On the basis of systématisation of several thousand radioactive element content analyses made in laboratories since the 50's, U and Th content of old granitoid rocks of Southern Transdanubia proved to be much higher than the average U and Th content of granitoids in the world. This value of rocks from areas west of Mecsek Mountains as well as near Szalatnak village and Pecs city is twice higher than the world average. Areas west of the Mecsek Mountains show higher U and lower Th contents than areas east of these mountains. Uranium accumulation is higher in aplites and hydrothermal formations than in granites. The western and eastern granites are less and highly sensitive to leaching, respectively. The intensive U migration resulted in significant U accumulation in young sediments in some places. INTRODUCTION Study of natural radioactive element (U /Ra1, Th, K) content of the rocks in Hungary was performed by the Mecseki Ércbányászati Vállalat (Mecsek Ore Mining Company) until 1990, when uranium exploration was stopped in Hungary. Aim of the analyses was to research U sources, therefore, rocks supposed to contain perspective U accumulation were mainly studied. The aim of this paper is to elaborate many thousands radiological data of granitoid rocks, gneisses and amphibolite-like metamorphic rocks coming from Southern Transdanubia (south of the Szekszárd-Kaposvár-Kutas line to the state boundary, and east of the Kutas-Csokonyavisonta-Barcs line to the Danube). -
Dicranum Scoparium Broom Fork-Moss Key 129, 135, 139
Dicranales Dicranum scoparium Broom Fork-moss Key 129, 135, 139 5 mm 5 mm 1 cm Identification A medium- to large-sized plant (up to 10 cm), growing in yellow-green to dark green cushions or large patches. The leaves are 4–7.5 mm long, narrowly spearhead-shaped and taper to a long fine tip composed largely of the strong nerve. They are often somewhat curved, but can also be straight and are hardly altered when dry. The leaf margins are usually strongly toothed near the tip. The back of the nerve has raised lines of cells which are just visible with a hand lens. These are also toothed, making the tip of the leaf appear toothed all round. D. scoparium occasionally produces deciduous shoots with smaller leaves at the tip of the stems. The curved, cylindrical capsule is common in the north and west of Britain, and is borne on a long seta that is yellow above and reddish below. Similar species D. scoparium is quite variable and confusion is most likely with D. majus (p. 379) and D. fuscescens (p. 382). D. majus is a larger plant with longer, regular, strongly curved leaves showing little variation; if in doubt, your plant is almost certainly D. scoparium. D. fuscescens is similar in size to D. scoparium, but has a finer leaf tip with smaller teeth on the margins and lacks raised lines of cells on the back of the leaves. The leaves in D. fuscescens are crisped when dry, and in this state mixed stands of D. scoparium and D. -

Dicranum scoparium and Porella platyphylla taxa of bryophytes were used in the present study carried out to determine the free radical scavenging activities, fatty acid, and vitamin contents. In this study, it was aimed to underline the importance of bryophytes for scientific literature and to provide a basis for further studies on this subject. The data obtained in this study indicate that the DPPH radical scavenging effect of D. scoparium taxon is significantly higher than that of P. platyphylla taxon. It is known that there is a strong relationship between the phenolic compound content of methanol extracts of the plants and the DPPH radical scavenging efficiency. When the fatty acid contents were examined, it was observed that levels of all unsaturated fatty acids were higher in the P. platyphylla taxon than the D. scoparium taxon, except for α-Linolenic acid. When the vitamin contents of species were compared, it was determined that D-3, α -tocopherol, stigmasterol, betasterol amount was higher in Dicranum taxon. Keywords: DPPH, Fatty Acid, Vitamin, Dicranaceae, Porellaceae Dicranum scoparium ve Porella platyphylla taxonlarının biyokimyasal bileşiklerinin serbest radikal temizleme faaliyetleri Öz Ülkemizde briyofitler ile ilgili olan çalışmalar genellikle briyofloristik amaçlı olup serbest radikal temizleme aktiviteleri ve yağ asidi içerikleri gibi diğer amaçlı çalışmalar yok denecek kadar azdır. -
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). -

Report of the Botanist 1868
) ;:; HEW Y««li BOTAPilCAL ( D. OAtOEN REPORT OF THE BOTANIST. Dr. S. B. WoolWORTH, Secretary of the Regents : Sir—The following report for 1868 is respectfully su])initted : The specimens of plants known as the " Beck Collection " have been taken from the folios, poisoned, and arranged in the cabinet case prepared for them. A few folios, containing the undistributed spec i mens of the collection, jet remain, there not being room for them in the case without too close pressing. The unmounted duplicate specimens of the State Herbarium have been arranged, with their proper labels, in the empty folios. The number of specimens* of the State collection that have been poisoned and mounted is about one thousand five hundred, representing four hundred and ten species, distributed as follows Phoenogamia, or flowering plants, one hundred and seventy-eight Cryptogamia, or flowerless plants, two hundred and thirty-two ; of which nine species are ferns, one lumdred and eighty mosses, and forty-three are liverworts. The names of the species are given in the accompanying list, marked A. In mounting the specimens of mosses, the species, so far as pos- sible, have been represented by series of specimens illustrating the different forms, variations in size, aspect, etc. In most instances a single plant has been separated from the tuft and placed by itself on the species sheet, that it may be seen individually as well as collect- ively. When the genus contains several or many species, the speci- mens of it have been prefaced by arranging a single plant of each species side by side on one sheet, thus giving, as it were, a synopsis <^^ of the genus. -
BOTANY,Degree 01H/Sub.,BRYOPHYTA :General Introduction.Dr.Dilip Kumar Jha (Lecture Series 19 ). Bryophytes Are the Simplest
BOTANY,Degree 01H/Sub.,BRYOPHYTA :General Introduction.Dr.Dilip Kumar Jha (Lecture series 19 ). ● Bryophytes are the simplest and first among terrestrial (land inhabiting) plants . ● They are non ‐vascular,non ‐flowering and non‐seeded. ● They are the first embryophytes (zygote develops into embryo ),first archegoniate (female sex organ is archegonium) which occupy an intermediate position between thallophyta (algae ) and pteridophyta. ● In bryophytes mechanical tissue are absent . Sex organs are stalked , multicellular and covered by single layered sterile jacket. ● In Bryophytes vascular tissue (xylem and phloem ) is absent. Thus, they are also called atrcheata. ● Bryophyta is a small group of plants including about 24000 species under 800 genera. Distribution and Habitat of Bryophytes ● Bryophytes are cosmopoliton in distribution .They are present in tropical and subtropical forests upto arctic region, upto height of appx 20000 feet on mountains. ● Bryophytes are probably not present in sea and antarctica. ● Bryophytes are terrestrial .They complete their vegetative phase on land but water is necessary for their reproduction.Thus,they are called amphibians of the plant kingdom. ● Bryophytes generally grow in moist and shady places eg.moist rocks,moist ground, tree trunks etc.Species of Sphagnum grows in boggy and marshy conditions. ● Some bryophytes are aquatic eg.Riccia fluitans,Ricciocarpus natans.Riella completes its life cycle fully under water. ● Some bryophytes grow as epiphytes on trunk of other plants eg.Dendroceros,Porella . ● Polytrichum juniperum,Tortula desertorum are some xerophytic bryophytes. ● Radula protensa grows on the fronds of fern ( epiphyllous ). ● Bryophytes are generally autotrophic.But,Buxbaumia aphylla and Cryptothallus mirabilis are saprophytic PLANT BODY OF BRYOPHYTE ● Bryophytes are first among the plant kingdom to show heteromorphic alternation of generation I.e. -

Adatok a Baranyai-Dombság Flórájához -..:::: Kitaibelia
17 KITAIBELIA XIII. évf. 1. szám pp.: 17-28. Debrecen 2008 Adatok a Baranyai-dombság flórájához PURGER Dragica Pécsi Tudományegyetem, TTK, Biológiai Intézet, Állatökológia Tanszék, H-7624 Pécs, Ifjúság útja 6. [email protected] Bevezetés A Mecseken és környékén végzett botanikai kutatások több mint kétszáz éves történetét HORVÁT Adolf Olivér munkái foglalják össze (HORVÁT 1942, 1958, 1975, 1976, 1977). Az elmúlt évtizedekben végzett florisztikai felmérések eredményei számos adattal gazdagították ismereteinket a Baranyai-dombság növényvilágáról (KEVEY 1986, 1988, 1995, 2001, KEVEY & HORVÁT 2000, DÉNES 1997, TÓTH 1998, 1999, 2000). Az utóbbi öt évben országszerte intenzív terepbotanikai kutatások folytak, és a legújabb eredmények (K EVEY 2004, PÁL 2002 a, b, 2003, PURGER 2002 a, 2002 b, CSIKY et al. 2005) arról tanúskodnak, hogy a vizsgált terület még sok feltáratlan botanikai értéket rejt. A vizsgált terület és módszerek A Baranyai-dombság a Mecsekt ől délre-délkeletre terül el. Négy részre tagolódik. Délen a Pécsi-síkság, attól északkeletre, pedig a Geresdi-dombság helyezkedik el. Legnagyobb részét a Dél-Baranyai dombság kistáj teszi ki. A Baranyai-dombság negyedik részét, mint egy sziget a Villányi hegység képezi (MAROSI & SOMOGYI 1990). Ez utóbbi tájegységet azonban e munkában mell őzzük, tekintettel arra, hogy a növényföldrajzi dolgozatokban a Villányi-hegységet általában külön (pl. MOLNÁR 1999), vagy a Mecsekkel együtt tárgyalják (pl. BORHIDI 2006). A félreértések elkerülése végett itt jegyzem meg, hogy az el őző cikkemben (PURGER 2002 a) a „Baranyai-dombság” név alatt a Dél-Baranyai dombságot értettem. Mindazonáltal, az egész térséget, és ezt a területet is, a geográfusok és a botanikusok több néven tárgyalyák: pl.: Mecsekalja (HORVÁT 1942), Tolna-Baranyai dombvidék (BORHIDI 2006, PÁL 2003).
