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.

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.     

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.     

The correct generic and specific name for “Acremoniella atra”

Acremoniella atra auct. is taxonomically identical withHarzia acremonioides (Harz) Cost. which is the type of the genusHarzia. Harzia Cost. 1888 must replace the illegitimate nameAcremoniella Sacc. 1886. Two new combinations—Harzia velata (Onions etJones)Hol.-Jech. andHarzia verrucosa (Togn.) Hol.-Jech. are proposed.     

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.     

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.     

Annotated chromosome numbers of selected asiaticPotentilla species

(2n=14) andP. sericea L. (2n=28). Taxonomy is briefly discussed. A new combinationP. micropetala D. Don subsp.byssitecta (Soják) Měsí?ek etSoják stat. nov. is proposed.     

Chromosome numbers in selectedHieracium species in the Krkonoše Mts. (the West Sudeten)

Chromosome numbers are given of 15 species of the genusHieracium L. s. str., representing seven species groups (in the sense of Flora Europaea, roughly corresponding to Zahn's “species principales”) from the Krkono?e Mts., N. Bohemia and SW Poland. For the first time chromosome numbers are reported forH. melanocephalum Tausch (2n=27),H. tubulosum Tausch (2n=36),H. schustleri Zlatník (2n=36),H. fritzei F. Schultz (2n=27),H. rohlenae Zlatník (2n=27),H. nigrescens Willd. (2n=36),H. decipiens Tausch (2n=36),H. atrellum Juxip inSchischkin etBobrov (2n=27),H. subnigrescens (Fries exNorrlin)Dahlst. (2n=36),H. sudeticum Sternberg (2n=36),H. pedunculare Tausch (2n=36),H. glandulosodentatum Uechtr. (2n=36),H. wimmeri Uechtr. (2n=27). InHieracium alpinum L. s. str. the number 2n=27 has been confirmed. The results show a high proportion of tetraploid taxa; no diploids have been found.     

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.

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.     

Ein Beitrag zur Nomenklatur sphinctozoider Schwämme (Porifera)

The sphinctozoid sponge generaFania Senowbari-Daryan 1990 andSpica Termier &Termier 1977 are preoccupied.Fania is replaced byFanthalamia nom. nov. andSpica by the younger synonymFistulispongia Termier &Termier 1977. The invalid subfamily name FaniinaeSenowbari-Daryan 1990 is replaced by Fanthalamiinae n. subfam. The invalid family and subfamily names SpicidaeTermier &Termier 1977 and SpicinaeSenowbari-Daryan 1990 respectively are replaced by FistulispongiidaeTermier atTermier 1977 and FistulispongiinaeSenowbari-Daryan 1990. The generaWaagenium de Laubenfels 1957 andCatubria Merla 1931 were previously overlooked.Waagenium DeLaubenfels 1957 is a younger synonym ofColospongia Laube 1865. The position ofCatubria Merla 1931 is uncertain. Most probablyCatubria is an alga.
