Some taxonomic changes withinLycopodiales

Some taxonomic and nomenclatural problems withinLycopodiales are discussed. InHyperzia Bernh. three subgenera have been distinguished, one of them described as a new one. With regard to a separate position ofLycopodium sect.Magellanica B. Øllgaard, a new genusAustrolycopodium Holub was proposed, comprising eight species mostly from the Southern Hemisphere. An analysis of the validity of the generic nameDiphasium C. Presl 1845 was carried out with an affirmative result. Six names for infrageneric taxa ofHuperzia and 44 new combinations for species have been proposed; in addition to those ofAustrolycopodium (8) they refer mainly toHuperzia (22) andPalhinhaea (9).     

Taxonomic and nomenclatural remarks onChamaenerion auct

The group of species usually referred toChamaenerion is maintained as forming a separate genus; asChamaenerion (auct.) is an illegitimate name,Chamerion (Raf. 1818)Raf. 1833 must be used as the correct name of the group. At presentChamerion includes 9 species; remarks on the nomenclature ofC. angustifolium (L., em.)Holub andC. dodonaei (Vill.)Holub are given.     

New names inPhanerogamae 3

New nomenclatural combinations are proposed, resulting from the adoption of a narrower concept of the generic classification unit or from necessary changes of the taxonomic rank in several taxa. A new genus—Anemonidium (Spach)Holub—is proposed inRanunculaceae. Four genera are accepted, includingChamaepitys Hill (Ajuga L. p. p.),Cota J. Gay (Anthemis L. p. p.),Euchiton Cass. (Gnaphalium L. p. p.) andRostraria Trin. (Koeleria Pers. p. p.+Trisetum Pers. p. p.).Genistella Ortega is preferred toChamaespartium Adans. In all 95 new combinations are proposed (83 for species, 11 for subspecies, 1 for a variety), including 21 inCota, 13 inRostraria, 11 inChamaepitys and 10 inEuchiton.     

New names inPhanerogamae 2

New nomenclatural combinations are proposed, necessitated mostly by the adoption of a narrower concept of the generic classificatory unit or, in some cases, by necessary changes of the taxonomic rank in several taxa. Explanatory comments on the taxonomic and nomenclatural problems are provided in the following genera:Aegonychon S. F. Gray (Lithospermum L. p.p.),Anemonastrum Holub andAnemonoides Mill. (Anemone L. p.p.),Bromopsis Fourr. (=Bromus L. p.p.),Calathiana Delarbre (Gentiana L. p.p.),Calcitrapoides Fabr. (Centaurea L. p.p.),Ciminalis Adans. (Gentiana L. p.p.),Pistolochia Bernh. (Corydalis Vent. p.p.),Psyllium Mill. (Plantago L. p.p.) andTephroseris (Reichenb.)Reichenb. (Senecio L. p.p.). In all 300 new combinations are proposed, including 17 inAnemonastrum, 32 inAnemonoides, 70 inBromopsis, 13 inCalathiana, 13 inCalcitrapoides, 29 inPistolochia, 40 inTephroseris and 25 inXanthoxalis.     

Validation of generic names inLycopodiaceae: with a description of a new genusPseudolycopodiella

Four earlier proposed and invalidly published generic names ofLycopodiaceae are validated:Lateristachys (type:Lycopodium laterale R. Br.),Lycopodiastrum (type:Lycopodium casuarinoides Spring),Pseudodiphasium (type:Lycopodium volubile G. Forster) andPseudolycopodium (type:Pseudolycopodium densum (Rothm.) Holub). A new genusPseudolycopodiella (type:Lycopodium carolinianum L.) is described. New nomenclatural combinations are proposed for 17 species of these genera and ofLycopodiella.

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.     

Ploidy variation in the group ofMyosotis palustris andM. laxa in the Czech Republic and Slovakia

In 74 natural populations of theMyosotis palustris andM. laxa groups from former Czechoslovakia three euploid and one aneuploid cytotypes were found that belong to the following species:M. nemorosa Besser, 2n=22,M. palustris (L.)Nath. em.Reichenb. inSturm, 2n=66,M. laxiflora Reichenb., 2n=66,M. radicans Opiz, 2n=66(64),M. brevisetacea (Schuster) Holub, 2n=66(64), andM. caespitosa C.F. Schultz, 2n=88. With the exception ofM. nemorosa, the chromosome numbers are published for the first time for the Czech Republic. The chromsome numbers, 2n=66, 2n=64 are found inM. brevisetacea, are new for the literature. The correlation between pollen size and ploidy level has been studied as well, and statistically significant differences were found between cytotypes belonging to different ploidy levels.     

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.     

Karyological and taxonomic observations onDracocephalum foetidum Bunge andKoenigia islandica L.

Chromosome numbers are reported for two Mongolian species,Dracocephalum foetidum Bunge (2n=12) andKoenigia islandica L. (2n=14). The relationship ofD. foetidum toD. moldavica L. (2n=10) and some patterns of phenotypic variation inK. islandica are briefly discussed. The following new combinations are proposed:K. cyanadra (Diels) Měsí?ek etSoják,K. forrestii (Diels) Měsí?ek etSoják,K. hubertii (Lingelsh.) Měsí?ek etSoják, andK. nummularifolia (Meisn.) Měsí?ek etSoják.     

Subspecies names from Berher,La flore des Vosges (1887)

Subspecies names have been studied from the nomenclaturally omitted bookBerher, La flore des vosges, 1887. A commented enumeration containing 107 names published in that book has been comiled. 41 subspecies names have been examined in more detail. Thirteen ofBerher's subspecific combinations may be employed in present taxonomic classifications. Nine ofBerher's names determine priority of the relevant subspecific epithets (parabasionyms). Two new nomenclatural combinations are proposed:Acetosa alpina subsp.amplexicaulis andBetula alba subsp.glutinosa. More detailed attention has been paid to the problems of names in the group ofRumex arifolius.

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.     

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 were karyologically examined for the first time, viz.T. trilobifolium Hudziok,T. lissocarpum agg.,T. paucilobum Hudziok,T. subalpinum Hudziok andT. mendax, a new pentaploid species. Taxonomic and nomenclatural notes are added.     

Notes on the biology ofBrachymeria [Neobrachymeria] nosatoi and its importance in the control ofNephantis serinopa

Nephantis serinopa Meyrick is now known to be parasitised by six species ofBrachymeria, viz.,B. nephantidis Gahan,B. lasus Walk.,B. excarinata Gahan,B. (Neobrachymeria) nosatoi Habu,B. euploeae Westw., andB. hime attevae Joseph Of these,B. (N.) nosatoi is the most effective pupal parasite ofN. serinopa in Kerala. Certain aspects of the biology of this parasite have been studied.     

Further taxonomic notes onRubiaceae in Europe

Several new names and combinations of EuropeanRubiaceae, i.e.Galium andCruciata, are proposed. The nomenclatorial interpretation ofGalium saxatile L. (=G. harcynicum Weigel) andG. megalospermum All. (=G. helveticum Weigel) is clarified. Among important publications from the year 1806Willdenow, Sp. Pl.4(2) has priority overSibthorp etSmith, Prodr. Fl. Graec.1 (part 1).
