LignicolousHyphomycetes from Czechoslovakia 8.Endophragmiella andPhragmocephala

Thirteen species and one variety ofEndophragmiella Sutton and three species ofPhragmocephala Mason etHughes collected by the author in Czechoslovakia, and occasionally in other regions of Europe are described and illustrated. Four new species and one new variety are described inEndophragmiella—E. aseptata Hol.-Jech.,E. fatrensis Holt.-Jech.,E. ramificata Hol.-Jech.,E. similis Hol.-Jech. andE. uniseptata (Ellis) Hughes var.pusilla Hol.-Jech..     

Notes on some African hepatic genera 6–9

The present study deals with African species ofSyzygiella Spruce,Allisoniella Hodgs. andGymnomitriaceae Klinggr. Three species ofSyzygiella Spruce,S. geminifolia (Mitt.) Steph.,S. concreta (Gott.) Spruce and one indeterminable species with orbicular leaves (known only in sterile condition) occur in Africa.Allisoniella nigra (Rodw.) Schust. represents a genus hitherto unreported for the African flora. The present knowledge ofGymnomitriaceae Klinggr. in subsaharan Africa is summarised; five species ofMarsupella Dum., one ofGymnomitrion Corda and five ofHerzogobryum Grolle are reported. Finally, some additions to the generaIsotachis Mitt.,Anastrophyllum (Spruce) Steph. andLophozia (Dum.) Dum. are presented.     

Echinodorus grandiflorus (Cham. etSchlecht.)Mich., its geographical distribution and variability

The taxonomy and geographical distribution ofEchinodorus grandiflorus (Cham. etSchlecht.)Mich. (Alismataceae) are stated. Former authors also included plants from southern Brazil and Argentina in this species, without the typical pellucid points on the blades; these belong to different species or to hybrids. The author further describes the hybrids ofE. grandiflorus with some other species of the same genus and two varieties.     

A review of the morphology and relationships of the Oligocene spikefish generaAcanthopleurus Agassiz 1844 andCryptobalistes Tyler 1968 (Tetraodontiformes: Triacanthidae)

A fish from the early Oligocene (Rupelian) of Canton Glarus, Switzerland,Cryptobalistes brevis (Rath 1859), until now placed incertae sedis among triacanthoid tetraodontiforms, is shown to be a triacanthid. It is redescribed and compared with the only other known fossil triacanthids, these being the two species ofAcanthopleurus, also from Canton Glarus, and with the seven Recent species of four genera. All of these triacanthids share five derived features. The four Recent genera are in a clade defined by five synapomorphies, andCryptobalistes andAcanthopleurus form an unresolved trichotomy with that clade. Reconstructions of the three fossil species are provided.     

Contribution to the knowledge ofEchinodorus macrophyllus (Kunth)Mich. andE. scaber Rataj from tropical America

The paper deals with the taxonomy and geographical distribution of the two species of the genusEchinodorus whichFassett (1955) did not work up satisfactorily in his revision i.e.Echinodorus macrophyllus (Kunth)Mich. whichFassett does not quote at all, andE. scaber Rataj whichFassett mistook forE. muricatus Griseb. Further a new variety and the diagnoses of hybrids, among whichE. punctatus Mich. is included, are cited.     

The stuttgart collection of oligocene primates from the fayum province of Egypt

In 1907, R. Markgraf made a small collection of Oligocene fossil primates from Egypt for the Staatliches Museum für Naturkunde in Stuttgart. Circumstances of discovery suggest that this collection came from the same stratigraphic horizon (the Upper Fossil Wood zone) and possibly the same locality as a similar collection made earlier that year byMarkgraf for the American Museum of Natural History in New York. Three new genera and species were described bySchlosser, based on the Stuttgart collection.Parapithecus fraasi Schlosser is a junior synonym ofApidium phiomense Osborn. “Parapithecus“grangeri Simons is placed in the new genusSimonsius. Propliopithecus haeckeli Schlosser andMoeripithecus markgrafi Schlosser have previously been recognized as synonyms. In addition,Aegyptopithecus zeuxis Simons is known from the Upper Fossil Wood zone.     

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.     

Lower Cambrian tubular micro-to macrofossils from the Paseky Shale of the Barrandian area (Czech Republic)

The carbonaceous megafossil (mega-alga)Marpolia spissa Walcott 1919 is described from the Early Cambrian of the Barrandian area for the first time. Macroscopic remains of colonies ofM. spissa are compared with tubular microfossils of the same rocks. Different areas in colonies ofM. spissa are assignable to several (part-based) genera and species of microfossils. Therefore, the microfossil taxaSiphonophycus robustum (Schopf 1968)Knoll et al. 1991,S. typicum (Hermann 1974)Butterfield 1994,S. kestron Schopf 1968,S. capitaneum Nyberg &Schopf 1984,Polytrichoides lineatus Hermann 1974, emend.Knoll et al. 1991,Tortunema angusta (Kolosov 1984)Butterfield 1994 andTortunema wernadskii (Schepeleva 1960)Butterfield 1994 should only be used as form-species in the sense of an artificial taxonomy. The palaeoenvironment of the Paseky Shale and the biological assignment ofMarpolia spissa are discussed.     

Taxonomic observations on some species of the genusParietaria

Taxonomy and distribution ofParietaria serbica.Pan?,P. lusitanica L.,P. micrantha Lebed. andP. mauritanica Dur. is briefly discussed.P. serbica is an endemic species of SE. Europe and is related toP. judaica Strand in L.P. lusitanica is divided into two subspecies.P. micrantha is treated as a variety ofP. lustitanica subsp.chersonensis (Lang) Chratek.P. mauritanica is reported as a new species for Sicily.     

Reclassifications and new names for some European Phanerogams

On the basis of taxonomic and nomenclatural revisions of various plant groups 37 new nomenclatural combinations are proposed mostly for European phanerogamous taxa (21 for species, 14 for subspecies, 2 for hybrids.)Medicula Medicus,Pseudofumaria Medicus andThlasidia Rafin. are accepted as taxonomically justified genera and correct generic names.Dactylorhiza longebracteata (F. W. Schmidt)Holub is proposed instead ofD. fuchsii (Druce) Soó, andHylotelephium triphyllum (Haworth) Holub isstead ofH. purpureum (L.)Holub.     

Bucania (Gastropoda) from the Ordovician of Estonia

Seven species ofBucania Hall 1847 from the Ordovician of Estonia are presented, also taking into consideration Pleistocene drift material from Germany, and their stratigraphical and geographical distributions are revised. The Middle Ordovician speciesBucania latissima Koken 1897 andBucania salpinx Koken 1897 are tentatively assigned toMegalomphala Ulrich inUlrich &Scofield 1897, while the Lower Ordovician speciesBucania macera Koken inKoken &Perner 1925 is placed inSalpingostoma Roemer 1876. The Middle OrdovicianBucania czekanowskii (Schmidt 1858) and the Upper OrdovicianBucania radiata (d’Eichwald 1856) were earlier considered conspecific, but based on study of the type material they are here considered distinct species.Salpingostoma cornu (Koken 1897), commonly referred to this genus because of the trema, is here transferred toBucania. Two Upper Ordovician specimens ofBucania display wide and abruptly flaring apertures morphologically far removed from other species of the genus.     

LignicolousHyphomycetes from Czechoslovakia 5.Septonema,Hormiactella andLylea

Three genera of lignicolousHyphomycetes Septonema Corda,Hormiactella Saac. andLylea Morgan-Jones are discussed. Illustrations and determination keys are provided. Five species ofSeptonema—S. fasciculare (Corda) Hughes,S. leptaleum (Ellis & Harkn.) Hughes,S. pinicola Hol.-Jech.,S. secedens Corda andS. laricium Hol.-Jech.—and two species ofHormiactella—H. fusca (Preuss) Sacc. andH. asetosa Hol.-Jech.—have been found in Czechoslovakia. A new speciesS. pseudobinum Hol.-Jech. is described from Romania.Septonema tetracoilum (Corda Hughes is accommodated in the genusLylea Morgan-Jones.     

The genusMicromeles revisited

Micromeles Decaisne emend.Koehne (Rosaceae, Maloideae) is shown to be generically distinct fromSorbus L. emend.Crantz. Problems in the taxonomy of the genus are reviewed. The genus appears to be most closely related toRaphiolepis Lindl. but is readily distinguished by a constant set of characters. Both genera may be derived fromSorbus L. emend.Crantz subg.Aria Pers. Analysis of morphological characters is provided. A survey for flavonoids revealed the presence of vitexin and/or luteolin 7-O-glucoside in some members of the genus in a pattern similar to that found in certain Asian species ofSorbus. There are also brief taxonomic notes on some of the species which were examined.     

Notes on the genusOenothera subsect.Oenothera (Onagraceae) in the Czech Republic

Up-to-date results of taxonomic and phytogeographic studies ofOenothera subsect.Oenothera in the eastern part of the Czech Republic (Moravia and Silesia) are presented. A new hybridogenous species,Oe. moravica Jehlík etRostański (=Oe. fallax × Oe. victorini), is described from S Moravia. Several taxa and hybrids are reported for the first time for the Czech Republic:Oe. victorini Gates etCatcheside (=Oe. rostanskii Jehlík),Oe. × wienii Renner exRostański,Oe. acutifolia × Oe. victorini. Other taxa are recorded from the eastern part of the Czech Republic for the first time:Oe. acutifolia Rostański,Oe. hoelscheri Renner exRostański,Oe. parviflora L.,Oe. subterminalis Gates. The taxonomy ofOe. pycnocarpa Atkinson etBartlett is discussed. A survey of species and hybrids ofOenothera subsect.Oenothera in the Czech Republic is added.     

Ein Beitrag zur Nomenklatur sphinctozoider Schwämme (Porifera)

The sphinctozoid sponge generaFania Senowbari-Daryan 1990 andSpica Termier &Termier 1977 are preoccupied.Fania is replaced byFanthalamia nom. nov. andSpica by the younger synonymFistulispongia Termier &Termier 1977. The invalid subfamily name FaniinaeSenowbari-Daryan 1990 is replaced by Fanthalamiinae n. subfam. The invalid family and subfamily names SpicidaeTermier &Termier 1977 and SpicinaeSenowbari-Daryan 1990 respectively are replaced by FistulispongiidaeTermier atTermier 1977 and FistulispongiinaeSenowbari-Daryan 1990. The generaWaagenium de Laubenfels 1957 andCatubria Merla 1931 were previously overlooked.Waagenium DeLaubenfels 1957 is a younger synonym ofColospongia Laube 1865. The position ofCatubria Merla 1931 is uncertain. Most probablyCatubria is an alga.     

Bemerkungen zu einigen balkanischenOxytropis-Arten

The present paper deals with the following three mountainOxytropis species:Oxytropis urumovii Jáv. inUrumov, an endemic species of the Pirin (Bulgaria);O. dinarica (Murb.) Wettst. distributed predominantly in Yugoslavia, andO. campestris which is common in the East Alps, but very rare in the Balkans. Three subspecies ofO. dinarica were distinguished: subsp.dinarica, subsp.weberi Chrtek etChrtková, and subsp.velebitica Chrtek etChrtková. In addition, a new combinationO. halleri Bunge exKoch subsp.korabensis (Kümmerle etJáv.)Chrtek etChrtková is given.
