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.

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.

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..     

LignicolousHyphomycetes from Czechoslovakia 1.Brachysporium

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.

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.

Indian species of the genusMirufens [Hym.: Trichogrammatidae]

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.     

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.     

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.     

New and critical species ofVicia in Iran and neighbouring countries 1. TheVicia variegata group

In Iran and the neighbouring regions of Turkey, Iraq, U.S.S.R. and Afghanistan, eight already known species belonging to the subsectionVariegatae Radzhi, occur:V. persica Boiss.,V. armena Boiss.,V. variegata Willd.,V. akhmaganica Kazar.,V. gregaria Boiss. etHeldr.,V. aucheri Jaub. etSpach and the two new species described here,V. rechingeri Chrtková-?ertová andV. afghanica Chrtková-?ertová. The occurrence of most species is restricted to a limited area which may be one of the evolutionary centres of this subsection.

Europe are elucidated.
