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.     

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.     

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.     

Bemerkungen zur Taxonomie und Nomenklatur vonLotus krylovii Schischk. etSerg. undL. corniculatus L. subsp.frondosus Freyn

Lotus krylovii Schischk. etSerg. undL. corniculatus L. subsp.frondosus Freyn sind zwei unterschiedliche Taxa, gekennzeichnet durch einige morphologische Merkmale.L. krylovii ist am nächsten mitL. tenuis Waldst. etKit. verwandt;L. corniculatus subsp.frondosus gehört in den Umkreis der Unterart vonL. corniculatus L., die im östlichen Teil des Areals der Art verbreitet ist. Nach ihrer Haupt-Verbreitung gehören die beiden Taxa zu den westasiatischen Arten.     

Der Jura-KrokodilierMachimosaurus H. v. Meyer

Up to nowMachimosaurus was known only from isolated teeth. Its systematic position was uncertain. Recently discovered remains ofMachimosaurus from the Upper Jurassic of Portugal allow a reconstruction of the skull. This find proves thatMachimosaurus belongs to the crocodilian family Teleosauridae. The genus comprises the only speciesMachimosaurus hugii H. v.Meyer. The speciesMachimosaurus mosae Sauvage & Liénard is based on heterogeneous material and is unmaintainable. Osteological characteristics show that the environment ofMachimosaurus was the open seas.     

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.     

The variability of critical species ofLotus L. in Iran and in the neighbouring countries II

The paper deals with some problems of distribution and variability of the speciesL. angustissimus L.,L. halophilus Boiss. etSprun.,L. laricus Rech. fil.,Aellen etEsfandiari, L.,schimperi Steud.,L. compactus Chrtková-?ertová,L. garcinii DC.     

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

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.     

Die systematische Stellung von Angustiphyllum cuneiforme n. gen. n. sp., einer eigenartigen Tetrakoralle aus dem Mitteldevon Nordspaniens

The newly found tetracoralAngustiphyllum cuneiforme n. gen. n. sp. from theGosseletia-Sandstein (Couvinium) of Candás/Prov. Oviedo (Northern Spain) is described and designed an ancestor of the so called “cuneate corals”Homalophyllum Simpson, 1900,Xenocyathellus Bassler, 1937 andHomalophyllites Easton, 1944 from the Devonian and Mississippian of North-America. Because of their undoubtful genetic relations the whole group of cuneate corals is joined to the subfamily Homalophyllidae n. subfam. within the family ZaphrentoididaeSchindewolf, 1938. Evidently the evolution developed in a progressive orthogenetic manner from the new genesAngustiphyllum (Middle Devonian) toXenocyathellus (higher Middle Devonian) andHomalophyllites (Mississippian), whileHomalophyllum (Middle Devonian) separated from this line in a early stage and thenceforth had its own evolution.     

Some new taxa inLotus corniculatus L.

Four new taxa in the variable speciesLotus corniculatus L. has been described: var.alandicus Chrtková-?ertová, var.norvegicus Chrtková-?ertová, var.fallax Chrtková-?ertová and var.posoniensis Chrtková-?ertová.     

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.     

Über böhmische und türkische Vertreter vonAnetoceras (Ammon., Unterdevon)

The Bohemian speciesAnetoceras solitarius (Barrande 1865) is re-described, including the TurkishA. barrandei (De Verneuil 1866). The other Bohemian species areA. aff.advolvens Erben 1960 and?A. fritschi (Barrande 1877). A new speciesA. recticostatum n. sp. is described from the German Lower Devonian, and several still problematical species of the genus are discussed. Finally, the supposed phylogenetic position and the relations ofAnetoceras are pointed out. The Upper SiegenianA. hunsrueckianum Erben 1960 is regarded as most primitive coiled ammonoid and as connecting link between the bactritids, and early coiled ammonoids.Mimosphinctes Eichenberg is considered to be a descendant fromAnetoceras.     

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.     
   
   

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.
