Danylyk I. M. & Kricsfalusy V. V. (2020): Phytogeographical differentiation of the genus Carex (Cyperaceae) in Saskatchewan, Canada. – Thaiszia – J. Bot. 30 (1): 001021.  –

Abstract: This paper presents a phytogeographical analysis of the genus Carex (Cyperaceae) in Saskatchewan, Canada. Carex (sedges) is the largest genus of vascular plants in the provincial flora, which includes 105 species used in our analysis. Phytogeographical differentiation of the genus was determined based on zonal, climatic, altitudinal and regional position of the study species. First of all, 15 zonal range types were identified. It was found that the majority of the study species are located in moderately cold or cold natural zones and have rather large range sizes with a high degree of disjunction. After that, the study species were classified into four climatic range types, situated within the significant impact of the severe continental climate. Later, four altitudinal range types, with a slight predominance of the group of species associated with the plain and low-altitude areas, were recognised. Finally, based on the geographic distribution of Carex species they were classified into four regional range types. Overall, the range formation of the genus Carex in Saskatchewan took evolutionary a long time and was driven by latitudinal species migration in two directions – to the northern and to a lesser extent the southern boundary of the province. The genus Carex in Saskatchewan demonstrates much stronger biogeographical affinities to America, than to East Asia and Europe. There is a fairly high number of bipolar Carex species which are distributed in the province at high northern latitudes.
Keywords: taxonomic composition, geographical distribution, range types.

Abstract: Lectotypification of Orchis purpurea Huds. × O. punctulata Steven ex Lindl. (Orchidaceae), described from the territory of Crimea, is proposed. The following data are presented: basionym, original nomenclatural citation, lectotype designated according to protologue and the repository of original specimen. Some taxonomical notes and data about its modern distribution are provided. The taxon was described as a hybrid, although later it was considered a species. In some publications the taxon is cited only in the remarks for  O. punctulata or O. purpurea, or is not mentioned at all. The contemporary natural distribution of the hybrid is Crimea, Caucasus, Asia Minor and Balkan Peninsula.
Keywords: Orchis punctulata, O. purpurea, O. ×wulffiana, Orchidaceae, lectotypification, distribution.

Abstract: Salvia hispanica L. native in S Mexico to Ecuador is now widely grown for its edible seeds (‘chia’). It has been recorded as a new alien species to the vascular flora of Bosnia and Herzegovina and the Balkans. In Bosnia and Herzegovina, S. hispanica is reported from two localities near the town of Žepče in Central Bosnia in November 2019. The specimens were growing along the banks of the Bosna River in the vicinity of the village Begov Han. Brief information on the species distribution in Bosnia and Herzegovina and a short morphological description is given.
Keywords: casual alien, chia, distribution, morphology, new record.

Krahulcová A. & Krahulec F. (2020): Ploidy level and breeding system in some populations of Pilosella (Asteraceae) in eastern and southern Slovakia. – Thaiszia – J. Bot. 30 (1): 037-058.  –

Abstract: The ploidy level/breeding system was determined in following species and hybrids originating from populations of the agamic polyploid complex of Pilosella in Slovakia: P. bauhini (either sexual tetraploids or apomictic pentaploids), P. hoppeana subsp. testimonialis, P. lactucella, P. onegensis (all three taxa diploid and so supposedly sexual), P. officinarum (pentaploids, hexaploids and octoploids, all cytotypes apomictic), P. glomerata (one pentaploid, another plant hexaploid and apomictic), P. macrostolona (apomictic hexaploids), P. schultesii, (mostly tetraploid, one plant an apomictic pentaploid), P. lactucella × P. onegensis (diploid and sexual), P. lactucella × P. aurantiaca (triploid and apomictic) and P. bauhini × P. officinarum (both sexual and apomictic tetraploids, apomictic pentaploids and apomictic hexaploids). The paper provides two karyological novelties in Pilosella: (a) A new hexaploid cytotype was revealed in Pilosella glomerata; (b) The octoploid apomictic and monoclonal plants of Pilosella officinarum were grown from seeds suggesting an occurrence of fruiting octoploid maternal plant(s). Such a cytotype would represent a new highest ploidy level detected in P. officinarum in the field. The cytotypes that were attributed both to P. officinarum and to the hybrids of P. bauhini and P. officinarum differed in a within-population clonal diversity. This effect could result from a different impact of (residual) sexuality and/or a different rate of origin of particular hybrid cytotypes. All findings presented in the paper are compared with published data on Pilosella species that refer preferentially to Slovakia, but also to a broader area in Central Europe.
Keywords: hawkweed, chromosome number, DNA-ploidy level, facultative apomixis, clonal diversity, Slovenský raj, Cerová vrchovina, Krupinská planina.

Evarts-Bunders P. & Evarte-Bundere G. (2020): Development and approbation of methodology for monitoring invasive plant species: the case of Latvia. – Thaiszia – J. Bot. 30 (1): 059-079.  –

Abstract: Categorisation of invasive alien species based on their impact is an important way to improve the management of biological invasions. The impact of 35 alien plant species in Latvia was evaluated based on information in the literature and certain studies of their environmental and socio-economic impacts. As a result, 15 priority monitorable species, or the Black List, have been evaluated, for which seven of the nine criteria set were met. The other 20 invasive plant species make up the list of monitorable invasive plants, or the Grey List. The list and methodology developed during the study were approbated in the vegetation season of 2016 in 16 randomly selected monitoring quadrates, which were further stratified according to geobotanical regions of Latvia, which is proportionally 1,57% from all 1017 quadrates of Latvia. In total, 34 alien species were identified during approbation of methodology as showing signs of invasiveness: 10 from Black List, 10 from Gray List and 14 other invasive species, not included in the monitorable species list of developed monitoring methodology. In general, half of the species found during approbation of the methodology are trees and shrubs that were deliberately imported into Latvia in the past to be used in landscape gardening. A large proportion (41%) of the invasive species encountered come from North America. The most commonly encountered invasive species are Elodea canadensis Michx., Impatiens parviflora DC. and Solidago canadensis L. The data obtained through the field approbation show that the areas rich in invasive species are covered by forests and transit corridors, but the areas where no invasive species have been detected are transition mires and raised bogs as well as intensively managed farmland. Following the developed methodology, it was concluded that 50% of the quadrates to be monitored should be randomly selected while maintaining the principle of geobotanical regions, while the other 50% should be selected in previously known invasive plant populations.
Keywords: alien plant, invasion, habitats, regional distribution, monitoring, Latvia.

Abstract: Taraxacum danubium is xerothermic species of Taraxacum sect. Erythrosperma occurring in Central Europe with the highest frequency in southeastern Czechia, northeastern Austria and southwestern Slovakia. Since its description in 1970 from Devínska Kobyla Hills in Slovakia the species was documented from numerous localities across the country, however overall study on the species distribution in Slovakia was still lacking. Thus in this paper, we present a detailed survey on its chorology in Slovakia based on our long-term field observation and data excerption from herbarium specimens with commentary on the distribution (over 60 localities in Slovakia) and biology of the species. Western Slovakia seems to be a centre of its distribution, while towards east the number of populations rapidly decreases. Karyology and ecology are discussed. The full list of locations and distribution map are presented.
Keywords: lesser dandelions, occurrence, Central Europe, xerothermic habitats, chorology.

Abstract: Analysis of chloroplast DNA sequences (trnL intron and trnLtrnF intergenic spacer) of the helophytic colony-forming Aglaodorum griffithii (Schott) Schott and other representative species of Araceae supported its placement within Aglaonema Schott. It is therefore proposed that Aglaodorum Schott should be recognised as a generic synonym of Aglaonema.

Berisha N., Ćušterevska R., Millaku F., Kostadinovski M. & Matevski V. (2020): Contribution to the knowledge on the flora of Mt. Luboten, Sharri Mts., Kosovo. – Thaiszia – J. Bot. 30 (2): 115-160. –

Abstract: With the aim of improving the floristic knowledge of Kosovo, here we present an inventory of the plant taxa recorded and collected between the March 2015 and September 2019, in the mountain massif of Luboten, Sharri Mts., SE Kosovo. Field surveys were conducted repeatedly for four years, on each vegetation season. With this work we aimed to provide detailed data concerning the vascular flora richness and distributional patterns. Floristic samples were studied in all representative habitats and sites, concerning climate, exposition, altitude and bedrock composition. This research led to the identification of a total 853 plant taxa of vascular plants, belonging to 354 genera and 93 families. Among these taxa, 82 are Balkan endemics and 53 are included into the Red Book of Vascular Flora of Kosovo. Out of them, 4 are critically endangered, 16 endangered, 3 vulnerable, 8 near threatened and 22 least concern. On the basis of the available floristic literature, 2 plant taxa are found to be new for Kosovo: Bromopsis cappadocica subsp. cappadocica and Pilosella macrotricha. At a national scale, we have found new distribution records for 17 taxa and additionally for 2 plant taxa: Ranunculus fontanus and Sesleria wettsteinii, conservation suggestions are provided. All natural habitats were classified according to EUNIS and their floristic richness is herein provided. Furthermore, the corresponding EUNIS habitat(s) for each taxon of where it was recorded to be growing are also indicated.

Arepieva L., Kulikova E., Abramova L., Golovanov Y., Bulokhov A. & Kharin A. (2020): Communities of the association Melilotetum albo–officinalis Sissingh 1950 in the European part of Russia and Belarus. – Thaiszia – J. Bot. 30 (2): 161-186. –

Abstract: The purpose of the study is to revise relevés of synanthropic communities dominated by Melilotus albus and M. officinalis from forest, forest-steppe and steppe zones of the European part of Russia and Belarus and to reveal the variation in their floristic composition in this territory. In the present paper, 66 relevés from 2004 to 2016 are analyzed. As a result of the study, the association Melilotetum albo–officinalis was identified. It includes three subassociations that reflect different ecological conditions and some geographical distribution features of communities. Subass. typicum includes the most typical communities. It has two variants. Communities of var. typica often contain few species due to the strong dominance of Melilotus albus and M. officinalis. Var. Ambrosia artemisiifolia includes early successional phytocoenoses affected by regular disturbances. The mesophytic communities which are rich in mesophilous meadow and ruderal species are assigned to the subass. tussilaginetosum farfarae. They tend to spread in the northwestern part of the study area located in the forest zone. Subass. сarduetosum acanthoidis includes xeromesophytic communities. Its coenoflora contains highly constant species of the order Onopordetalia acanthi and a high proportion of subcontinental and continental species. They are widespread in the eastern part of the study area, in steppe and forest-steppe zones. Еnvironmental differences between habitats of the described communities are shown using targeted ecological indicator values. The highest variability between syntaxa was identified in the levels of moisture in soils and substrates, temperature, continentality and hemeroby.
Keywords: syntaxonomy, ass. Melilotetum albo–officinalis, subassociations, variants, ecological differentiation, geographical distribution of plant communities.

Iamonico D. (2020): Nomenclature survey of the genus Amaranthus (Amaranthaceae). 10. What is Amaranthus commutatus? – Thaiszia – J. Bot. 30 (2): 187-196. –

Abstract: The name Amaranthus commutatus, originally validated by Kerner for a plant taxon from Hungary and Slovakia, was studied as part of a series of contributions with the final aim to clarify the complicated nomenclature of the genus Amaranthus. On the basis of the protologue, the name Amaranthus commutatus cannot be associated with any European species, while out of Europe, Kerner’s original data of A. commutatus may match the morphology of the Australian species A. rhombeus. Unfortunately, no original material has been traced so far and thus no lectotype can be designated (Arts. 9.3 and 9.4 of Shenzhen Code). Consequently, neotypification is desirable according to Art. 9.8. However no specimens of Amaranthus seen by Kerner have been traced and it was very difficult to understand Kerner’s concept of that taxon. Having no suitable specimens available, I prefer to avoid the designation of a neotype, and the possible synonymization of A. commutatus with A. rhombeus based just on Kerner’s data. Furthermore, the synonyms cited by Kerner in the protologue [Amaranthus blitum var. polygonoides (here lectotypified on a specimen preserved at K), and A. blitum var. prostratus (lectotype designated by Iamonico in 2016 on a Balbis’ illustration] refer to other species, i.e. A. albus (new proposed synonymy) and A. deflexus, respectively. The treatment of Amaranthus commutatus appears inconsistent but this fact is not ground for rejecting of the name since does not threat any other name and there are no disadvantageous nomenclatural changes (Art. 56.1). Since the failure to properly designate a type, and the impossibility to reject A. commutatus, Kerner’s name continues to be of ambiguous nature and is proposed as listed as a name incertae sedis.
Keywords: Bulgaria, Hungary, incertae sedis, nomenclature, new synonym, Slovakia, typification.

Marcinčinová M., Širka P. & Dudáš M. (2020): The lichen flora of the Košice Zoological Garden (E Slovakia). – Thaiszia – J. Bot. 30 (2): 197-207. –

Abstract: The Košice Zoological Garden offers a wide range of habitats from sunny exposed meadows, hedges and semi-natural well-lit to shaded forests with brooks together with concrete paths and animal cages. To best represent the area, 14 locations were selected. Total of 61 species were recorded. Most of the recorded species were epiphytic or epigeic; epilithic species were limited to a few limestone boulders or anthropogenic substrates. Besides common and widespread nitrophilous species, two recorded species are critically endangered (Arthonia radiata, Parmelia submontana), four are endangered (Evernia prunastri, Flavoparmelia caperata, Graphis scripta and Pleurosticta acetabulum), one is vulnerable (Usnea hirta), while eight are listed as near threatened in Slovakia. The discovery of Bryoria sp. is particularly interesting because of missing records of this species in the area. The lowest altitude of 412 m a.s.l. for Parmelia submontana in Slovakia was recorded. The region provides a suitable environment for a wide spectrum of lichen species and is worth of our biodiversity conservation concerns.
Keywords: lichen diversity, endangered species, air pollution, Carpathians, biodiversity.
