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.     

Some new nomenclatural combinations I

Twenty new nomenclatural combinations are proposed for various taxa.Haloscias Fries 1846 (aff.Ligusticum L. 1753),Hylebia (Koch)Fourr. 1868 (aff.Stellaria L. 1753) andStuckenia Börner 1912 (aff.Potamogeton L. 1753) are accepted as separate genera,Acetosella (Meisn.)Fourr. 1869 is included inAcetosa Mill. 1754.     

Chromosome counts and chromosome morphology of some selected species

In the years 1976–1981 we studied chromosome counts and karyotypic formulae of the following 29 species of plants from 41 localities (of these 6 from Bohemia, 32 from Moravia, 3 from Slovakia):Batrachium baudotii (Godron) F. W. Schultz,Chenopodium rubrum L.,C. polyspermum L.,C. murale L.,C. ficifolium Sm.,C. opulifolium Schrader ex DC. inLam. et DC.,C. strictum Roth [subsp.strictum, subsp.glaucophyllum (Aellen)Aellen inJust etAellen, subsp.striatiforme Uotila],Arenaria grandiflora L.,Illecebrum verticillatum L.,Spergula morisonii Boreau inDuchartre,Spergularia marginata (DC. inLam. et DC.)Kittel S. marina (L.)Griseb.,S. rubra (L.)

Pomel)Dvo?ák],S. officinale (L.)Scop.,Descurainia sophia (L.)Webb exPrantl inEngler etPrantl,Nasturtium officinale R. Br. inAiton,Barbarea arcuata (Opiz inPresl J. et C.)Reichenb.,Lunaria annua L.,Soldanella montana Willd.,S. carpatica Vierh. inUrban etGraebner,Lotus tenuis Waldst. etKit. exWilld.,L. uliginosus Schkuhr,Trigonella monspeliaca L.,Geranium sibiricum L.,Lactuca tatarica (L.)C. A. Meyer.     

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.     

Selected chromosome counts of the Czechoslovak flora III

Chromosome numbers compared with as yet published data are given for the following 12 Phanerogams (both native species and aliens) from Czechoslovakia:Ambrosia trifida L.,Cardamine chelidonia L.,Dephne cneorum L.,Epipactis albensis Nováková etRydlo,Linum flavum L.subsp flavum, Lunaria rediviva L.,Nepeta grandiflora M.BIEB.,Reseda luteola L.,Thlaspi montanum L.,Tithymalus salicifolius (Host)Klotzsch etGarcke,Tithymalus virgultosus (Klokov) Holub andVerbascum speciosum Schrad. subsp.speciosum. The chromosome number 2n=40 is presented for the first time in autogamousEpipactis albensis Nováková etRydlo. New chromosome numbers were found inCardamine chelidonia L. (2n=32) and inTithymalus salicifolius (Host) Klotzch etGarcke (2n=40). Known but less frequent cytotypes are reported inLinum flavum L. subsp.flavum (2n=28) and inVerbascum speciosum Schrad. subsp.speciosum (2n=30).     

Observations on the floral morphology of someDioscorea species (Dioscoreaceae) in Nigeria

Observations on floral morphology of eight species ofDioscorea L., namely,D. bulbifera L.,D. dumetorum (Kunth) Pax,D. hirtiflora Benth.,D. minutiflora Engl.,D. preussii Pax,D. odoratissima Pax,D. rotundata Poir. andD. Smilacifolia De Wild. are presented. The most remarkable distinctive features of the taxa studied are: the presence of large fruits and raceme inflorescences inD. preussii, the absence of pendulous inflorescences inD. dumetorum, and the absence of stalks in female flowers ofD. bulbifera.     

Untersuchungen über den PolyploidkomplexVeronica cymbalaria agg. (Scrophulariaceae)

Veronica panormitana Tin. inGuss. (sparsely distributed from Corsica and Sicily to Syria) andV. trichadena Jord. etFourr. var.freyniana M. Fisch. (Mallorca) are diploid (2n = 18), and very probably the ancestors of the allopolyploidV. cymbalaria Bod. The latter consists of tetraploid (2n = 36) and hexaploid (2n = 54) strains (confirmed on new material from Italy, Greece, and Turkey). The diploid taxa are morphologically well separated from each other and fromV. cymbalaria, whereas the tetraploids and hexaploids are not separable morphologically.—Another poorly known diploid strain from Kurdistan is described as new:Veronica cymbalaria Bod. var.baradostensis M. Fischer.—V. panormitana is reported from Greece for the first time.

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.
