The arthropodBundenbachiellus giganteus from the Lower Devonian Hunsrück Slate, Germany

The large Hunsrück Slate arthropodBundenbachiellus giganteus (Broili, 1929) has been interpreted as a myriapod, a possible arthropleurid, and most recently as a distorted specimen of the arachnomorph arthropodCheloniellon. The Single specimen lacks the head region and is characterised by a narrow trunk bearing a series of biramous appendages with a segmented endopod and filamentous exopod. A reinvestigation demonstrates that it is not referable toCheloniellon but represents a distinct taxon of whichEschenbachiellus wuttkensis Briggs &;Bartels, 2001, also based on a Single Hunsrück Slate specimen, is a junior synonym. Minor features ofStürmer &;Bergström’s (1978) reconstruction ofCheloniellon, which were based on the holotype ofBundenbachiellus giganteus, are revised.

An account is given of 4 new species ofMirufens Girault:M. brevifuniculata Khan & Shafee, M.albiscutellum Khan & Shafee,M. magniclavata Khan & Shafee andM. longiclavata Khan & Shafee. A key to Indian species of the genusMirufens is also provided.     

Revision der Familie HippocardiidaePojeta & Runnegar, 1976 (Mollusca; Rostroconchia)

Following the revision and integration of the family PseudobigaleaidaeHoare, Mapes &; Yancey into the existing systematic concept of the rostroconch order Conocardiida the original family of hood-carrying rostroconchs, the HippocardiidaePojeta &; Runnegar, is revised and subdivided in this contribution. Here, we present the members of the subfamily HippocardiinaePojeta &; Runnegar [n. subfam.]. Its erection appeared necessary first, as the family Hippocardiidae had been used for decades as a conglomeration taxon where most varied morphotypes were assigned to the type genusHippocardia, whose character combinations only just now can be distinguished, and secondly because the number of hood-carrying hippocardiid rostroconch taxa increased markedly during our studies. Ten taxa at the species level are assigned to the generaHippocardia Brown, 1843,Bieberiana n. gen.,Cartericardia n. gen.,Fraipontia n. gen.,Hoareicardia n. gen. andPojetorum n. gen. All the taxa are precisely diagnosed and described at the subfamily, genus and species level by a uniform, revised and completed terminology of morphologic characters. This allows comparability of the taxa and aids in the reconstruction of phylogenetic relationships in the Hippocardiinae [n. subfam.], whose members occur from the Late Silurian until the Mississippian.     

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.     

Polyploidy and variation in theCampanula rotundifolia complex. Part II. (Taxonomic) I. Revision of the groupsSaxicolae,Lanceolatae andAlpicolae in Czechoslovakia and adjacent regions

A survey is given of three natural groups of the subsectionHeterophylla (Witas.)Fed. of the genusCampanula L. Within theSaxicolae four taxa of higher rank have been revealed:c. xylocarpa Kovanda (2n=34),C. gentilis Kovanda (2n=34),C. moravica (Spitzner)Kovanda subsp.moravica (2n=68), andC. moravica subsp.xylorrhiza (O. Schwarz)Kovanda (2n=102). BothAlpicolae andLanceolatae are represented by a single species: the first byC. cochleariifolia Lam. (2n=34), the latter byC. serrata (Kit. ap.Schult.)Hendrych (2n=34). Cytology, ecology and geographical distribution of all these taxa have been reviewed, and relationships to the other members of the complex discussed. Infraspecific variation within each species has also been examined.     

Verbeitung einiger seltenen und subendemischen Arten der griechischen Flora mit taxonomischen und chorologischen Betrachtungen

The taxa very rare in Greece,Gentianella bulgarica (Velen.)J. Holub andPrimula elatior (L.)Hill subsp.intricata (Gren. etGodron)Lüdi Balkan-South Carpathian and mountain subendemic taxon of South and South-Central Europe also the oreophytesGentiana asclepidaea L. andAndrosace villosa L. rare in Greece at high altitudes endemic species of Central Europe and arcto-alpic element both extending South as far as Central Italy and Central Greece as well as the relatively rare species in Greece,Crocus biflorus Mill. which exists in South Europe from Sicily and eastwards and finally four otherIridaceae, i.e.: the South Balkan Asia-Minor subendemic speciesCrocus olivieri Gay andC. pulchellus Herbert, the South Balkan endemic speciesC. veluchensis Herbert and the Mediterranean and mostly East-para-mediterranean subendemic speciesHermodactylus tuberosus (L.)Miller are reported and investigated. However new habitats and records in the Greek area of the investigated species are given, their distribution is discussed, while the existence of the taxa most rare in GreecePrimula elatior (L.)Hill subsp.intricata (Gren. etGodron)Lüdi inHegi,Gentianella bulgarica (Velen.)J. Holub,Gentiana asclepiadea L.,Androsace villosa L. andCrocus biflorus Mill. are presented in the form of a dot map and thus the southernmost limits of their spreading in the Balkan peninsula or in S.E. Europe are elucidated.     

A revision of the moss genusCrossidium (Pottiaceae) with the description of the new genusMicrocrossidium

A world revision of the genusCrossidium Jur. recognizes 11 species, which are described and discussed in the context of important taxonomic characters. An identification key is provided.C. asirense Frey & Kürschner is reduced to synonymy withC. davidai Catcheside, and the geographical range ofC. laevipilum Ther. & Trab. is extended to Europe. Phylogenetic trends are interpreted on the basis of two main evolutionary lines associated with the presence or absence of hyaline hair-points on the leaves. A twelfth species is transferred toMicrocrossidium Guerra & Cano, gen. nov., asM. apiculatum (Magill)Guerra & Cano, comb. nova, because of differences in stem anatomy, peristome configuration, and spore morphology.     

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.     

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.
