The effects of various aphids as larval prey on the development ofMetasyrphus corollae [Dipt.: Syrphidae]

The suitability of thirteen aphid species for the polyphagous larvae ofMetasyrphus corollae (Fabr.) was investigated in laboratory tests. The length of larval and pupal development, weight of puparia, mortality during larval and pupal stages were compared. Cannibalism was not observed in the larvae reared in groups on suitable food.Aphis sambuci Linneaus was not a suitable prey for the larvae.Cavariella theobaldi (Gillette Bragg) collected fromPastinaca sativa L. was toxic to larvae ofM. corollae, although it was possible to rear the larvae onAphis fabae Scopoli orAnuraphis subterranea (Walker) from the same host plant.     

Notes on some African hepatic genera 1–5

The present study deals with five genera of hepatics in Africa, Isotachis Mitt., Anastrophyllum (Spruce) Steph., Tritomaria Schiffn. ex Loeske, Gymnocoleopsis (Schust.) Schust. and Lophozia (Dum.) Dum. All African populations of the genus Isotachis Mitt. are considered to be one species, I. aubertii (Schwaegr.) Mitt. Four species of Anastrophyllum (Spruce) Steph. (s.l.), A. auritum (Lehm.) Steph., A. piligerum (Nees) Spruce, A. subcomplicatum (Lehm. et Lindenb.) Steph. and A. minutum (Schreb.) Schust., and two species of Tritomaria Schiffn. et Loeske, T. camerunensis S. Arnell and T. exsecta (Schrad.) Schiffn. ex Loeske occur in Africa. Gymmocoleopsis multiflora (Steph.) Schust. represents a genus and species hitherto unreported for the African flora. Finally, five Lophozia (Dum.) Dum. species, L. argentina (Steph.) Schust., L. capensis S. Arnell, L. decolorans (Limpr.) Steph., L. hedbergii S. Arnell and L. tristaniana (S. Arnell) Váňa, are reported from central and southern Africa; two of these (L. argentina (Steph.) Schust. and L. decolorans (Limpr.) Steph.) represent the first reports from Africa.

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.     

New chromosome counts in nine endemic species from Iran

Original meiotic chromosome counts are presented for nine endemic species in seven families of Angiosperms from Iran including:Arum giganteum Ghahr. (Araceae) (n=14),Caccinia actinobole Bunge (Boraginaceae) (n=8),Delphinium aquilegifolium (Boiss.)Bornm. (Ranunculaceae) (n=8),Diplotaenia damavandica Mozaff., Hedge etLamond (Apiaceae) (n=11),Gypsophila caricifolia Boiss. (Caryophyllaceae) (n=17),Iphiona arachnoidea (Boiss.)Anderb. (Asteraceae) (n=9),Moltkia gypsacea Rech. f. etAellen (Boraginaceae) (n=20),Onobrychis gaubae Bornm. (Fabaceae) (n=8) andOnosma platyphyllum Riedl (Boraginaceae) (n=9). Eight counts are reported for the first time. Furthermore, the previous chromosome count forIphiona aracnoidea is corrected. Based on cytological data the species status ofMoltkia gypsacea is confirmed; it is not merely synonymous withM. coerulea (Willd.)Lehm. The basic chromosome number n=11 is reported in the genusDiplotaenia for the first time.     

A revision of the genusOlpitrichum Atk

A revision of the genusOlpitrichum Atk. was undertaken, revealing three species:O. macrosporum (Farlow exSacc.)Sumstine,O. patulum (Sacc etBerl.)Hol.-Jech. andO. tenellum (Berk. etCurt)Hol.-Jech.O. macrosporum andO. tenellum occur on decayed cotton bolls,O. patulum on dead rotten wood and bark. Aspergilliform phialosporous state has been found inO. macrosporum andO. patulum.     

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.

Survey and distribution ofCybocephalidae [Coleoptera] in Israel

Nine species ofCybocephalus were found in a survey conducted throughout Israel:C. micans (Reitter),C. nigriceps nigriceps (J. Sahiberg),C. nigriceps sinister Endrödy-Younga,C. aegyptiacus Endrödy-Younga,C. mediterraneus Endrödy-Younga,C. pullus Endrödy-Younga,C. fodori minor Endrödy-Younga,C. membranaceus (Reitter) andCybocephalus sp. n.C. micans andC.n. nigriceps are the most prevalent: the former in the Coastal Plain on citrus and the latter in the Arava region on date palms. In most cases the population density of the predator appeared to be related to that of the prey. Armoured scale insects(Homoptera: Diaspididae) were the main prey ofCybocephalus.

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.     

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.     

Determination of host range in relation to systematics forPeristenus stygicus [Hym.: Braconidae], A parasitoid ofMiridae

Peristenus stygicus Loan develops inMirinae speciesLygus hesperus,Knight,L. lineolaris, (Palisot de Beauvois) andPolymerus basalis (Reuter),Orthotylinae speciesLabopidicola geminata (Johnston),Phylinae speciesPseudatomoscelis seriatus (Reuter) and partially develops in the mirineDichrooscytus sp. The parasitoids attackMicrophylellus maculipennis (Knight) (Phylinae) and another orthotyline species, but do not develop in these.Taedia johnstoni (Knight) (Mirinae), 2 species ofBrycorinae and 3 species ofLygaeidae are not acceptable as hosts. Olfactometer studies show the parasites are significantly more attracted to lygus nymphs whenPhaseolus vulgaris L. is present than either the nymphs or bean alone. Host color, mobility, size, previously infested plant material, and host plant species are rejected as host selection criteria.     

Scanning electron microscopic study of anamorphs of someBasidiomycetes in culture

The anamorphs in cultures ofLepista nuda (Bull.:Fr.)Cooke,Coprinus comatus (Müll.:Fr.)S.F. Gray,Fistulina hepatica Sohaeff.:Fr.,Pholiota adiposa (Fr.)Kumm. andAsterophora lycoperdoides (Bull.)S.F. Gray, an imperfect state ofNyctalis lycoperdoides (Bull.)Schroet., were studied by scanning electron microscopy. Arthroconidia were described inLepista nuda for the first time. Examination of the fine structure of dendroid forms inCoprinus comatus revealed why those structures were not propagative.     

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.
