Some chromosome numbers of the CzechoslovakLeguminosae

Chromosome numbers of the Czechoslovak species of the genusLotus, from various localities have been determined. The paper includes the speciesLotus uliginosus Schkuhr,L.tenuis Waldst. etKit. andL. borbásii Ujhelyi.     

The variability of critical species ofLotus L. in Iran and in the neighbouring countries I. the circle ofL. corniculatus L. andL. gebelia Vent.

The region of Iran, Iraq, Afghanistan and the neighbouring countries is important for some groups of the speciesLotus L., especially those of the circle ofL. corniculatus L. andL. gebelia Vent. The first group is represented by the speciesL. corniculatus L. with 4 subspecies (3 of which are important for this region), andL. tenuis Waldst. etKit. which here attains the eastern boundary of the continuous area of distribution, and by the eastern speciesL. krylovii Schischk. etSerg. andL. rechingeri Chrtková-?ertová. The second group is represented by the speciesL. gebelia Vent.,L. michauxianus Ser. in DC. andL. libanoticus Boiss. their areas of distribution covering mostly those regions. Most of the species show considerable variability within the species.     

Beiträge zur Sedimentation und fossilführung des hunsrückschiefers 14.Viriatellina fuchsi (Kutscher, 1931) im Hunsrückschiefer und im Tentaculitenknollenkalk thüringens

The new genusViriatellina Bou?ek, 1964 unites the two older species namedNovakia gemündina Runzheimer, 1932 andTentaculites fuchsi Kutscher, 1931. ThusViriatellina gemuendina (Runzheimer) is cancelled, on the other handViriatellina fuchsi (Kutscher) remains valid. RecentlyViriatellina fuchsi (Kutscher) has been found in the tentaculitiferous limestone of Thuringia.     

New subfamily Proschizophoriinae of dalmanellid Brachiopds

Proschizophoria Maillieux is restudied and found to be related to the Silurian genusIdiorthis McLearn and a new genusCordatomyonia, type speciesCordatomyonia shupei, n. sp.Proschizophoria, Idiorthis, andCordatomyonia are united in the new subfamily Proschizophoriinae which is assigned to the dalmanellid family Rhipidomellidae. Rhipidomellidae and its included subfamilies Heterorthinae, Rhipidomellinae, and Proschizophoriinae are emended and newly diagnosed. A new dalmanellid genus,Megasalopina, is proposed for the Lower Devonian species“Dalmanella” elevata Williams & Breger and its allies. It is thought to have been derived from the draboviinid genusSalopina Boucot and therefore belongs to the Schizophoriidae.Dalmanellopsis Khalfin is removed from the synonymy ofLevenea and is shown to be related toSalopina.     

Holothurien-Sklerite aus dem Dachsteinkalk (Ober-Trias) der nördlichen Kalkalpen

By dissolving Dachstein-limestone with acetic acid, Holothurian sclerites were obtained, i. e. sieve plates and wheels. One new species of the genusCalclamna, two new species of the genusCalclamnella, and the well known speciesFissobractites subsymmetrica Kristan-Tollmann were received within the family Calclamidae. For the first time the family Priscopedatidae is represented in the Triassic by two new species of the genusPriscopedatus and byStaurocumites cf.bartensteini Deflandre-Rigaud. Within the family Theeliidae four new species can be adjoined to the genusTheelia whileAcanthotheelia spinosa Frizzell & Exline could be confirmed by comparison.     

Karyo-taxonomic study of the genus<Emphasis Type="Italic">Pseudolysimachion</Emphasis> (<Emphasis Type="Italic">Scrophulariaceae</Emphasis>) in the Czech Republic and Slovakia

Flow cytometry was used to determine ploidy levels in the Czech and Slovak taxa of the genusPseudolysimachion (W.D.J. Koch)Opiz (=Veronica auct. p.p.,Scrophulariaceae). In total, 123 populations from the Czech Republic, Slovakia, Ukraine (one locality), Austria (one locality) and Hungary (one locality) were analyzed. InP. maritimum (L.)Á. Löve etD. Löve andP. spicatum (L.)Opiz, two cytotypes were found: diploid (2n=2x=34) and tetraploid (2n=4x=68). In both species the tetraploid cytotype predominated (P. maritimum: 41 tetraploid populations out of 45;P. spicatum: 57 tetraploid populations out of 58). The two cytotypes ofP. maritimum have no taxonomic significance because ploidy level is not obviously correlated with morphology, distribution pattern or ecology. Tetraploid populations ofP. spicatum belong to two morphologically different subspecies, subsp.spicatum and subsp.fischeri Trávní?ek. The diploid cytotype (one population only) should be provisionally classified as a third subspecies ofP. spicatum, which is morphologically similar to the Asian subsp.porphyrianum (Pavlov)Trávní?ek. Only diploid plants (2n=2x=34) ofP. orchideum (Crantz)Wraber were found; all 13 populations that were analyzed belong toP. orchideum s.str. One diploid population sample ofP. spurium subsp.foliosum (Waldst. etKit.)Holub (2n=2x=34) and one tetraploid sample ofP. incanum subsp.pallens (Host)Trávní?ek (2n=4x=68) were also analyzed. In addition, three tetraploid populations of hybrid origin were investigated:P. maritimum ×P. spicatum subsp.spicatum (one population) andP. maritimum ×P. spurium subsp.foliosum (two populations). While hybrid plants ofP. maritimum ×P. spicatum arose from tetraploid parental species, plants ofP. maritimum ×P. spurium probably resulted from a cross between tetraploidP. maritimum and diploidP. spurium. The putative origin and evolutionary importance of polyploids in thePseudolysimachion are discussed.     

Cytotaxonomic notes on the generaIndigofera L. andCyamopsis DC.

Continuing cytotaxonomic research in the generaCyamopsis andIndigofera, this time with attention payed for the greater part to East Tropical African species yielded the following results:

1. 1.
   Except for four rather small subsections ofIndigofera proper and the related genusRhynchotropis Harms, information was obtained about all Taxa. Of the 283 species described inGillett'ss monograph, some 80 species, among them a few with subspecies and varieties, now have been cytologically examined.     
   
   

Die GattungEridoconcha Ulrich & Bassler (Eridostraca) im Mitteldevon von Ost-Thüringen

The presence of the genusEridoconcha Ulrich & Bassler 1923 (Eridostraca) is reported for the first time from the Lower Paleozoic sediments of Germany. The three speciesE. spinosa n. sp.,E. papillosa n. sp., andE. cf.rugosa Ulr. & Bassl. are described from the Lower Middle Devonian of eastern Thuringia.     

Some notes onCornaceae

Colmeiroa F. v.Muell. ist a later homonym and therefore a new name is proposed—Paracorokia. Its systematic position is discussed: it seems to belong toCornaceae rather than toEscalloniaceae. SubgenusDiscocrania Harms of the genusCornus is published in a generic rank.

Differentiation of species in Gonioloboceras

The type specimen ofGonioloboceras goniolobum (Meek), rediscovered by Spath in the British Museum, is the foundation for a more accurate comparative study of this and other species ofGonioloboceras.Gonioloboceras described asG. goniolobum byElias in 1938 is differentiated asGonioloboceras schmidti, new species. Suture sets (new term) for several growth stages inG. goniolobum (Meek),G. welleriSmith,G. schmidtiElias, G.eliasiMiller &Owen, andG. asiaticumLibrovitch are assembled and used for differentiation of the species.The Kazakhstan goniatite faunule containingG. asiaticum is considered of very late Pennsylvanian age.     

On the taxonomy ofPuccinia sieversiae Arth. and some remarks on the phylogeny of the rusts onGeeae

Puccinia tatrensis Urban onGeum reptans in Czechoslovakia is recognized as a subspecies ofPuccinia sieversiae Arth.Puccinia waldsteiniae, P. gei andP. gei-parviflori appear to be the most ancient rusts known on the tribeGeeae and it is assumed that their common ancestral form was already present in the Cretaceous period.Puccinia sieversiae is more advanced and has its centre of origin and spread in Central Asia. Phylogenetically most advanced and at the same time most differentiated from each other are species ofPhragmidium, i.e.P. circumvallatum andP. miyabeanum.     

Zur Entwicklung und Taxionomie der Tricornidae (Ostracoda) in Mitteleuropa

This paper is an attempt to summarize the existing knowledge on the Tricornidae Contrary toBlumenstengel (1965) the range of the family is vastly extended and its position as well as the taxonomic significance of its characteristic features are discussed. Several trends as to lateral view, strengthening of sculpture and marginal structures can be discerned within the entire generic group consisting ofOvornina—Tricornina—Bohemina—Saalfeldella. Probably these genera listed constitute a genuine phylogenetic line. The author gives a review on the range and delimitations of the most important genera. As a new genusOvornina (type speciesTricornina ovata Blumenstengel 1962; Ordovician—Devonian) is described; new subgenera of the same genus areOvornina andTricornella.     

Some new taxa ofPotentilla L.

Five new species and two varieties from the sectionMultifidae are described from the Sino-Himalayan region. They are referred to the affinity ofP. multifida L. andP. griffithii Hook. f.; one of the new species is probably related toP. gerardiana Lindl. and one is intermediate between the species of the sectionsMultifidae andNiveae.     

Protein characters and relationship betweenPhaseolus vulgaris ssp.Aborigineus Burk. and related taxons of the genusPhaseolus

Both quantitative and qualitative immunochemical methods were used for studying the mutual relationships of several spocies and the subspecies of the genusPhaseolus: Ph. vulgaris L. ssp.vulgaris, Ph. vulgaris L. ssp.aborigineus Burk.,Ph. coccineus L.,Ph. acutifolius A. Gray,Ph. lunatus L. (American endemites) andPh. aureus L. (a typical Asian bean). Protein characters of cotyledons (i.e., ?storage” proteins) of the above species were compared with the aid of antisera prepared against seed (cotyledon) proteins ofPh. vulgaris L. ssp.vulgaris, cv. Veltruská Saxa, using

Glacial relics in the bryoflora of the highlands Českomoravská vrchovina (Bohemian-Moravian Highlands); Their habitat and cenotaxonomic value

The paper sums up the information which the author has so far collected about the habitats and phytocenotic conditions of the glacial relics ofScorpidium scorpioides (Hedw.) Limpr.,Calliergon trifarium (Web. etMohr.)Kindb.,Paludella squarrosa (Hedw.) Brid., andMeesia triquetra (Hook. etTayl.)Aongstr. in the Highlands ?eskomoravská vrchovina (Bohemian-Moravian Highlands) in Czechoslovakia.

Schädelknochen vonCeratodus Agassiz aus dem Stubensandstein (Trias,Mittl. Keuper 4) Württembergs und ihre Bedeutung

Notice is given of the first skull-bones ofCeratodus rectangulus Linck found in the Germanic Trias; they have been compared with those ofC. sturii Tell. and the recent genusEpiceratodus. The number of fossil teeth ofCeratodus is much larger, relatively, than that of the bones of the skull. This is explained by the assumption that these dipnoans were not embedded in their natural biotops.     

Morphology and distribution ofKerpina Struve (Devonian Atrypida)

The anomalous atrypid brachiopod genusKerpina Struve (family AtrypidaeGill) is restricted in distribution to Eifelian (Middle Devonian) rocks of the Eifel region, Germany, and is found associated with, or attached to, the platy tabulate coralAlveolites. Both coral and brachiopod appear to be characteristics of a currentagitated shallow water environment. The marked variation in shell shape and beak incurvature, as well as the unique internal morphology of the type speciesKerpina vineta Struve are described for the first time.
