ClassAsteretea tripolium on the territory of the former USSR and Mongolia

Higher syntaxa of the classAsteretea tripolium are reviewed. This class covers plant communities of the Euro-Asian continent on low- and medium-salinized soils with medium moisture conditions where perennial herbaceous plants (hemicryptophytes) of non-succulent character prevail. On the territory of the former USSR and Mongolia, the classAsteretea tripolium is represented by the following orders:Glauco-Puccinellietalia Beeftink etWesthoff inBeeftink 1962,Cirsietalia esculenti Mirkin etV. Golub exV. Golub ord. novus,Scorzonero-Juncetalia gerardii Vicherek 1973,Halerpestetalia Mirkin et al. exV. Golub ord. novus,Artemisio santonicae-Limonietalia gmelinii V. Golub etV. Solomakha 1988,Suaedetalia corniculatae V. Golub ord. novus. Superspecies and aggregations of species are used for the diagnosis of higher syntaxa.     

LignicolousHyphomycetes from Czechoslovakia 3.Sporoschisma,Sporoschismopsis andCatenularia

A revision ofTaraxacum sect.Piesis (Compositae)

On the basis of allozyme and cultivation data, and of additional herbarium material, a taxonomic and nomenclatural revision ofTaraxacum sect.Piesis A.J. Richards exKirschner et?těpánek is provided. The section is made up of halophilous, sexually reproducing taxa. InT. stenocephalum Boiss. etKotschy,T. pindicum Kirschner et?těpánek, sp. nov., andT. perenne Kirschner et?těpánek, sp. nov., a tetraploid chromosome number has been recorded, representing the only known case of sexuality at the tetraploid level in the genus. The complex ofT. stenocephalum, includes some geographically and morphologically extreme populations treated as subspecies: subsp.gumusanicum (Soest)Kirschner et?těpánek, comb. nov., subsp.magnum Kirschner et?těpánek, subsp. nov., and subsp.daralagesicum (Schischk.)Kirschner et?těpánek, comb. nov. In addition toT. bessarabicum (Hornem.)Hand.-Mazz., a widely distributed Eurasian species,T. stenocephalum, a complex centred in Transcaucasia and Anatolia, andT. pachypodum H. Lindb., a North African endemic, four new species are described:T. salsum Kirschner et?těpánek, sp. nov., a diploid endemic confined to E Crimea,T. perenne Kirschner et?těpánek, sp. nov., a tetraploid sexual species known only from SW Crimea,T. pindicum Kirschner et?těpánek, sp. nov., a remarkable tetraploid endemic to the Pindos Mts., Greece, andT. salsitatis Kirschner, ?těpänek etYirdirimli, sp. nov., an Anatolian diploid species. Furthermore, a hybrid betweenT. salsum andT. bessarabicum from Crimea (documented on the basis of allozyme data elsewhere) is given a binomial,T. xmesohalobium Kirschner et?těpánek, nothosp. nov.     

DieFestucetali valesiacae-Gesellschaften im Ostteil des Gebirges České středohoří (Böhmisches Mittelgebirge) I. Die Pflanzengesellschaften

Die Xerothermrasengesellschaften auf tertiären vulkanischen Gesteinen im Ostteil des Gebirges České středohoří (Böhmisches Mittelgebirge) wurden analysiert und nach der Zürich-Montpellier-Methode klassifiziert. Im Einklang mit der bisherigen Entwicklung der phytozönologischen Nomenklatur-Regeln ist für jedes Syntaxon der korrekte Name nach dem Prioritätsprinzip festgelegt. Fünf Assziationen gehören in dasAlysso-Festucion pallentis Moravec 1967 und drei in dasFestucion valesiacea Klika 1931 (KlasseFestuco-Brometea Br.-Bl. et Tx. 1943, OrdnungFestucetalia valesiacae Br.-Bl. et Tx. 1943). DasFestuco valesiacae-Stipotum capillatae Sillinger 1931 wurde aus Böhmen noch nicht angegeben und für dasAsperulo glaucae-Festucetum duriusculas Preis inKlika 1939 undMelico transsilvanicae-Sempervivetum soboliferi Preis inKlika 1939, die bisher aus synthetischen Tabellen bekannt waren, sind die ersten Vegetationsaufnahmen angeführt. Weiter werden publiziert:Alysso saxatilis-Festucetum duriusculae Klika exČeřovský 1949,Allio montani-Sedetum albi Klika 1939,Alysso montani-Potentilletum arenariae Preis 1939,Carici humilis-Festucetum sulcatae Klika 1951 undErysimo crepidifolii-Festucetum valesiacae Klika 1933. Jede Assoziation ist mit Vegetationsaufnahmen und der Synonymik belegt und ihre charakteristische Artenkombination, Artenzusammensetzung und Struktur, ihre syngenetischen und topographischen Beziehungen werden beschrieben und ein Vergleich mit der Literatur ist durchgeführt.
