      Forty-five taxa (32 species, 11 varieties and two forms) of Racomitrium have been reported from China. Among them, six species and two varieties of Racomitrium were originally described as new based on specimens collected from China. Based on this revisional study, 23 species of Racomitrium are considered to be taxonomically recognizable entities in China. Racomitrium joseph-hookeri Frisvoll is new to China. The new combination, Orthotrichum delavayi (Broth. et Par.) Cao based on Racomitrium delavayi, is made. Racomitrium varium (Mitt.) Jaeg. and R. occidentale (Ren. et Card.) Ren. et Card. should be excluded from bryoftora of China. A key to Chinese species of Racomitrium is given. The geographic distributions of Racomitrium species in China are discussed.

      According to “Index Muscorum” the genus Fleischerobryum Loeske has four species, S (Hampe) Loeske, F. macrophyllum Broth., F. eurybrochis (Ren. & Card.) Fleisch., and F. wallisii (C. Müll.) Loeske. The two latter belong to the related genus Philonotis Brid. and have been synonymized.

      The capsule of Fleischerobryum shows several primitive characters: The position of the capsule is horizontal or slightly pendulous, the capsule is long cylindrical or slightly asymmetric, the neck is large, ca one third of the length of the capsule, and the striae of the exothecium of Fleischerobryum are less regularly organized than are the striae in Philonotis species with ovoid or gibbous and horizontal capsules. Evolutionary lines from the primitive capsule of Fleischerobryum both to gibbous and regularly striate capsules, and to upright smooth capsules with reduced peristomes are possible. Fleischerobryum macrophyllum and F. longicolle have wide mammillose basal leaf cells and narrower more distinctly mammillose/papillose cells in the apical leaf like some Philonotis species. In the basal cells the mammilla is proximal, and in the distal cells the papilla/mammilla is distal. In the mid-leaf cells of Fleischerobryum, cells both with central papillae and with distal papillae are present. In Philonotis, with a few exceptions, the site of the papillae/mamillae is fixed either to the distal end or proximal end of the cell, on both cell ends, or papillae are central on the cell. A hypothesis is here presented that the ancestor of Philonotis, and possibly of all Bartramiaceae, was a plant having a capsule similar to that of the Fleischerobryum, and wide and smooth leaf cells.

      An analysis of the architecture of the Lembophyllaceae is presented and its value in the taxonomy of the family is assessed. The Lembophyllaceae produce a variety of growth forms, ranging from creeping mats to loose erect-ascendant wefts and pendant fronds. Characters of stem orientation, branching, rhizoid distribution, leaf orientation, size and shape, and the production of determinate or indeterminate growth are used to describe merophyte development. Variation in the pattern of merophyte development yields an architectural pattern common to taxa, and the genera differ from each other in their relative expression of this pattern. The same architecture is therefore seen to underlie the various growth forms exhibited.

      A cladistic analysis of Chinese genera of family Sematophyllaceae was conducted. The family, as defined traditionally, was shown to be paraphyletic. Isocladiella, Taxithelium and Callicladium were shown nested outside the Sematophyllum clade. Brotherella-Wijkia-Acanthorrhynchium-Warburgiella and Heterophyllium-Clastobryopsis-Gammiella are two sister clades of Sematophyllum clade.

      Results of morphological and anatomical studies of the sporophytes of Takakia ceratophylla are presented based on Chinese plants. Taxonomic relationship of Takakia is discussed. Takakia ceratophylla has a unique capsule-wall thickening which functionally causes the incurve of valves. There is a regular spiral line of dehiscence on the capsule which is derived from two rows of epidermal cells less incrassate at maturity and also on the green capsule. Spiral twisting of the capsule and seta seems to be useful for more efficient spore dispersal. In several features the sporophytes of Chinese populations of this species are larger than those of the Aleutians.

      CO2 exchange (CO2 assimilation, dark respiration), potential photochemical activity and blue and red fluorescence ratios (F450/F690, F690/F735) of the desiccation-tolerant (DT) ectohydric moss (Tortula ruralis) and two DT lichens (Cladonia convoluta and C. furcata) from a temperate semidesert grassland during desiccation and rehydration are reported. Optimal water content for carbon fixation (RWC = 100%) was less than 50% of the saturation water content in all investigated species. The water-content compensation point of CO2 assimilation was also low and ranges 6-8% of saturation water content. Thylakoid membrane activity as measured by slow chlorophyll fluorescence is unchanged through a broader range of water content. On rehydration photosynthesis recovered fully and rapidly within 1 h in all three species. The low water content requirement for net CO2 assimilation in the three DT species allows them to revive periodically and prosper during the dry seasons. These plants can gain water from dew or air humidity at dawn and maintain slight positive carbon balance day by day. During the desiccation-rehydration cycles blue/(far)red and red/far red fluorescence ratios (F450/F690, F450/F735, F690/F735) suggest changes in cell volumes and in the optical properties of the plants rather than shifts in the photosynthetic pigment and secondary metabolite levels.

      Investigation on effects of human interferences (i.e. pollution in the widest sense) to stream bryophyte vegetation was carried out at four mountainous areas in Hungary. The bryophyte associations of the sections affected by human disturbance were uniform independently of the substrate. The diversity of bryophytes was lower than in other stream sections and Amblystegium species as A. riparium, A. humile, and A. serpens were very frequent in each level. Although the stream sections investigated were situated in natural conservation areas of Hungary, 10% of them belonged to this category.

      The lipophilic constituents of liverworts have been studied using 1H NMR spectroscopy by extracting small samples of the liverworts with the NMR solvent CDCl3. One application of the technique has been to compare samples of Adelanthus decipiens of different origin, including herbarium specimens; of particular interest is a re-investigation, using a voucher specimen, of material that was the subject of a GC-MS study in 1981. The strength of the technique is demonstrated by the finding that compounds previously thought to be eudesmanolides are actually wettsteins A and B, two of the ten highly oxygenated naphthalenes and acetophenones identified in Adelanthus decipiens. The 1H NMR spectrum of the extract of one sample of Cryptothallus mirabilis showed that one compound was predominant in the extract; this compound is 15-acetoxypinguisone, a simple derivative of the sesquiterpene ketone first isolated from Aneura pinguis, a fellow member of the Aneuraceae.

      The bryoflora of Xinjiang consists of 417 species and subspecific taxa distributed in 163 genera and 55 families. Among them 61 species, 31 genera, and 21 families are hepatics. The floristic characteristics and geographical distribution of Xinjiang bryophytes are analyzed. The similarity coefficients of the bryophyte genera between Xinjiang and six such regions as Altai Mountain of Russia, Mongolia, Inner Mongolia, Xizang, Qingling Mts., and NE China are calculated. The data indicate that the floristic affinities between Xinjiang and its adjacent regions are close to each other. The geographic distribution of Xinjiang bryophytes are divided into five regions:(1)Altai Mountain Region; (2)Tianshan Mountain Region; (3)Kunlun Mountain Region; (4)Jungar Basin Region; (5)Tarim Basin Region.

      The moss flora of Thailand contains a total of 621 species and 31 subspecific taxa distributed among 191 genera and 52 families. Endemism of the flora is estimated at 6% at the species level. The floristic composition and phytogeographical connections of Thai mosses are analyzed. Overall taxonomic diversity is compared among East Asian, Malesian, and the Thai moss floras. The study suggests that Thai land is a transitional region forming a bridge between the Malesian and Sino-Himalayan floras. Two floristic regions, the Sino-Himalayan region in the north and northeast and the Malesian region in the southeast and peninsular Thailand, are represented by the Thai moss flora. The mosses of high elevations in the north exhibit affinities to those of eastern Himalayas, southwestern China, and Indochina. In the south, most species occurring there belong to the Malesian elements known from Malay Peninsula, Java, Sumatra and its archipelago, and the Philippines. A list of families and genera of Thai mosses with information on number of species in each genus is provided.

      Sweden has a bryophyte flora of slightly more than 1000 species. Of these, 24% or 241 taxa are redlisted. Some examples of habitats rich in bryophyte species are described. Forest is the main terrestrial habitat in Sweden. However, 95% of this is being managed and cut for commercial purposes. Among the most important habitats for conservation action today are the remnants of old-growth forests. The major threat to bryophytes is forestry, agriculture, air pollution and lack of knowledge. Deposition of both sulphuric acid and nitrogen compounds is still extensive and has negatively affected the abundance of some species. Damming of water courses for hydroelectric purposes has destroyed many shores along rivers and lakes. Roughly 90% of all larger river systems is affected by dams and by water regulation from reservoir operations. Many riverine habitats are lost and the taxonomic richness has been lowered considerably in water regulated rapids in North Sweden. In the agricultural landscape, the intensified cultivation on fertile soil and the abandonment of poor soils has led to fewer bryophyte species on both arable land and untilled marginal land. The alpine region is the only major landcape in Sweden where the bryophyte flora is considered to be virgin and very little affected by man. The total protected area in Sweden amounts to almost 6% of the total land area of the country and most of this area consists of high-altitude landscapes. However, most redlisted species occur in the lowlands. The protection of species in Sweden is mainly done by establishing nature reserves on known sites and habitats of particular importance for wild plants and animals.

      The moss communities of the southern Fildes Peninsula region (including Ardley Island) of King George Island, South Shetland Islands, are classified and described, based on species composition, physiognomy and structure, and ecological factors. Two principal moss-dominated formations class, Antarctic moss tundra and Antarctic moss swamp, are recognised. Within the Antarctic moss tundra, eight formations are recognised with 18 associations defined. Within the Antarctic moss swamp two formations and two associations are recognised. The development and distribution of these communities is determined by water supply and stability of the substrate. The characteristics of the communities are discussed and species richness, evenness and diversity determined.

      The first botanical collections from the Antarctic regions were made from the South Shetland Islands in 1820; on Cockburn Island of the north east tip of the Antarctic Peninsula, in 1843; and from Cape Adare, northern Victoria Land (the first continental Antarctic collection) in 1895. Since then most expeditions have made biological collections, now scattered amongst a great many institutions and different countries. The flora of Antarctica includes only 2 vascular plants, around 100 mosses, 25-30 hepatics, 250 lichens, and around 700 terrestrial and aquatic algae, confined to the 2% of its 14 million km2 area that is ice free. Historically, most studies have been of a biogeographic nature, with comparatively few critical taxonomic appraisals. While there are a number of apparently endemic taxa, particularly amongst the lichens, recent critical studies have shown that under the severe climate many morphotypes have been incorrectly determined. There is an increasing extra-Antarctic and Bipolar element in the flora. Logistic difficulties, lack of specialists interested in the Antarctic flora, differing taxonomic interpretations and, often, poor collections, compound the difficulties associated with the study of the flora. Despite this, a renewed interest in phytogeography and biodiversity, and the application of new methodologies such as ecophysiology and molecular genetics, is leading to new insights on the origin and biodiversity of the flora, and potential impacts of global climate change. The time is now ripe for a coordinated and integrated methodological approach to the study of this fascinating region and its flora.

      Sporophytes and spores from the liverwort Pellia epiphylla (L.) Corda have been examined for their secondary metabolites and compared to those from the gametophytes. The sporophytes contained five africanane-type sesquiterpenes, epi-swartzianin A, 9(15)-africanene, isoafricanol, leptographiol, and the new 10β-hydroxy isoafricanol, the new humulane derivative 1,8-humuladien-5-ol, caryophyllene oxide, phytol, and (1,2)-bis-nor-phytone. Further substances were palmitic acid, linolic acid methyl ester, 7, 10, 13-hexadecatriene acid methyl ester, octadecanol and three bisbibenzyls: perrottetin E, 10'-hydroxy perrottetin E and 10'-hydroxy perrottetin E-11-methyl ether. Caffeic and ferulic acid methyl esters could be obtained from the more polar extract along with four flavones: luteolin, luteolin-7-methyl ether, luteolin-7,3'-dimethyl ether and the new luteolin-5,7,3'-trimethyl ether.

      Column and thin-layer chromatography revealed the presence of the following carotenoids in the thalli of 72 specimens of Cladonia portentosa from various dune habitats on the Danish Wadden Sea island of Fanø: α-carotene, β-carotene, β-cryptoxanthin, zeaxanthin, lutein, lycopene-5,6-epoxide, antheraxanthin, lutein epoxide, violaxanthin, neoxanthin, hydroxyechinenone, adonixanthin, canthaxanthin, astaxanthin, capsochrome and apo-6'-lycopenal. The total content of carotenoids ranged from 12.05 (specimen no. 8827, group I) to 89.36μg g-1 dry mass (specimen no. 8913, group XVII). The carotenoid composition of the analysed specimens varied to such an extent that the taxonomic significance is negligible. Based on these results and previous papers, the biological role of the carotenoids and their possible use in lichen taxonomy is discussed.

      The influence of acute gamma radiation on three physiological characteristics and the lipid and fatty acid composition in Peltigera aphthosa and Hypogymnia physodes was investigated. Photosynthetic intensity in P. aphthosa decreased with increasing radiation dose. Respiratory intensity, membrane permeability and composition of individual lipids in both lichen species appeared to be relatively stable after radiation doses of 100 and 1000 Gy. A dose of 10000 Gy decreased the respiratory intensity, caused damage to cell membranes and considerable changes in lipid composition. As far as fatty acids concerned, gamma radiation stimulated their desaturation.
