Tan, K., Sfikas, G. & Vold, G. 1997:Viola parnonia (Violaceae), a new species from southern Greece. — Ann. Bot. Fennici 34: 149–152.
Viola parnonia Kit Tan, Sfikas and Vold (Violaceae), a new species endemic to the peak of Mt Parnon in the Peloponnese, southern Greece, is described and illustrated. Its affinities are with V. euboea (Halácsy) Halácsy and V. graeca (W. Becker) Halácsy.
Göktürk, R. S. & Sümbül, H. 1997: A new species of Cephalaria (Dipsacaceae) from South Anatolia, Turkey. — Ann. Bot. Fennici 34: 153–155.
A new species is described from South Anatolia: Cephalaria ekimiana R. S. Göktürk & H. Sümbül (Dipsacaceae). The closest species to this one is Cephalaria lycica Matthews. The main features that differentiate Cephalaria ekimiana from C. lycica are that all bracts are dark brown margined, the involucral bracts are orbicular and the involucel has eight equal or subequal teeth (not 4 long and 4 short teeth) and the stem is much taller.
Søchting, U. 1997: Epiphyllic cover on spruce needles in Denmark. — Ann. Bot. Fennici 34: 157–164.
Epiphyllic microbial cover on Norway spruce (Picea abies) needles has increased in recent years in Denmark and in neighbouring countries. Based on a survey of 2445 needles from seven localities in Denmark and Poland, the development of the microbial crust through 11 needle generations was analysed. An algal crust consisting of mainly Apatococcus lobatus (Chodat) Boye-Petersen and Desmococcus viridis Brand is built up during the first four years, peels off during the subsequent three years whereafter a new crust starts accumulating. These crusts are frequently colonized by two fungi, Scolecotheca cornuta Søchting & Sutton and Capronia sp. The amount of microbial cover on the needles did not reflect the varying levels of nitrogen deposition within the area.
Iqbal, S. H. 1997: Species diversity of freshwater hyphomycetes in some streams of Pakistan. II. Seasonal differences of fungal communities on leaves. — Ann. Bot. Fennici 34: 165–178.
Significantly more fungal species colonized leaves in summer, spring and autumn during the first week of submersion than in winter. Higher amounts of dry leaf mass were lost in summer, spring and autumn than in winter. Rapid loss of dry mass was accompanied by rapid development of a fungal community. Colonization and sporulation rates varied with each fungal species. Maximum frequency of occurrence of fungal species were reached earlier (3–4 weeks) in summer and spring communities than in communities of autumn (4 weeks) and winter (6 weeks). More conidia were produced per milligram plant material in winter and autumn than in summer and spring. Flagellospora curvula dominated the communities in autumn, winter and spring while Lunulospora curvula dominated the summer community. The occurrence of rich fungal communities on leaves in four seasons is due to the availability of deciduous substrata contributed by the riparian vegetation, supplemented with seasonal addition of wheat and rice straw and enrichment of the canal water with phosphates and nitrates washed down from the bordering fields.
Frahm, J.-P. 1997: A taxonomic revision of Dicranodontium (Musci). — Ann. Bot. Fennici 34: 179–204.
The 39 species of Dicranodontium which are currently included in the genus are critically revised and reduced to 7. Dicranodontium fleischerianum Schultze-Motel could not be separated from D. uncinatum (Harv.) Jaeg. and is regarded as synonymous with the latter. Dicranodontium dimorphum Mitt. has proven to be synonymous with D. didictyon (Mitt.) Jaeg., D. meridionale Bartr. with D. pulchroalare Broth., D. ceylonense Fleisch., D. subasperum Williams and D. perviride Dix. & P. Varde are synonymous with D. denudatum (Brid.) Britt., D. subintegrifolium Broth., D. attenuatum (Mitt.) Wils., D. caespitosum (Mitt.) Par. and D. decipiens (Mitt.) Mitt. ex Broth. are synonymous with D. didymodon (Griff.) Par., D. blindioides (Besch.) Broth., D. sparsum Dix. are synonymous with D. uncinatum (Harv.) Jaeg. Dicranodontium sinense (C. Müll.) Par. is identical with Campylopus japonicus Broth. and recognized as Campylopus sinensis (C. Müll.) J.-P. Frahm comb. nov. Dicranodontium falcatum Broth. (described as endemic from Hawaii) is synonymous with D. porodictyon Card. & Thér. from China, D. tanganyikae J. Tayl. & P. Varde is identical with Campylopus flexuosus (Hedw.) Brid. var. incacorralis (Herz.) J.-P. Frahm, D. humilis P. Varde is a species of Blindia, D. interruptum P. Varde is identical with Bryohumbertia filifolia (Hornsch.) J.-P. Frahm, D. horricuspis Card. and D. capillifolium (Dix.) Takaki are synonymous with D. asperulum (Mitt.) Broth. Dicranodontium brasiliense Herz. is placed as subspecies in D. pulchroalare. Dicranodontium intermedium Allen is placed into Atractylocarpus and recognized as A. intermedius (Allen) J.-P. Frahm comb. nov. Dicranodontium insularum Bartr. and D. tristaniense Dix. & Thér. belong to Dicranoloma. Dicranodontium tenii Broth. described from China is identical with Dicranum hamulosum Mitt. from Japan. Dicranodontium tenuinerve Dix. & Sak. described from Japan is identical with Bryohumbertia subcomosa (Dix.) J.-P. Frahm. Dicranodontium filifolium Broth. seems not to belong to this genus, but its systematic position is dubious. Dicranodontium subporodictyon Broth. is transferred to the genus Dicranum Hedw. and recognized as D. subporodictyon (Broth.) Gao. The types of Dicranodontium tapes (C. Müll.) Par. and D. papillifolium Gao were not available, but it is very unlikely that these species belong to this genus.
