(Received: 6 March 2019; Accepted: 16 July 2019)

The distribution of Sonchus palustris in Slovakia was studied using herbarium specimens and literary sources. The herbarium studies, supplemented with targeted field search in the years 2015–2018, revealed 61 new localities and confirmed many other older locations. The species has been recorded in 19 phytogeographical districts and sub-districts of Slova- kia. Most of the records are concentrated in the Podunajská nížina lowland in SW Slovakia and in the Ipeľsko-rimavská brázda region in southern Slovakia. Our results showed that the species is relatively common in different types of wetlands and its re-evaluation in the recent version of the Slovak red list is not needed. Chromosome number data for two new populations in eastern Slovakia (both 2n = 18) were counted. The distribution map is given.

INTRODUCTION

According to Boulos (1973, 1974a, b) there are more than 50 species within the genus Sonchus L. (Asteraceae, Cichorieae, Sonchinae) arranged into three subgenera with centre of distribution in Europe, Northern America and Mid- dle Asia (Meusel and Jäger 1992). Sonchus palustris L. (syn. Sonchus paluster L.) naturally occurs in temper- ate, non-Mediterranean Europe from northwestern England to the Caucasus and Uzbekistan (Lansdown 2014, Meusel and Jäger 1992). It has also been reported from Pakistan (Qureshi et al. 2002). The species is considered as ex- tinct in Switzerland (Bornard et al. 2016). Secondary occurrence was found in North America (Brunton and Crompton 1993). The research based on ITS sequences supports the inclusion of S. palustris to highly polyphyletic subgenus Sonchus, section Maritimi and series Palustres (Kim et al. 2007).

The oldest literature record of S. palustris was published by Genersich (1798) from northeastern Slovakia from damp places and fens in the Spiš (= Zips) region. 30 years later, Endlicher (1830) published finding in the surroundings of Bratislava (southwestern Slovakia). Hazslinszky (1847) states more precisely the locality in the Spiš region near the village of Lipovce (= Lipovec, Lipócz). Other authors published few data on the species’ occurrence in southwestern (Knapp 1863, Résely 1867, Reuss 1853, Schiller 1864), northeastern (Hazslinsz- ky 1853, Kárpáti 1939), western (Kárpáti 1939, Krzisch 1857, Mikeš 1938) and southeastern (Hazslinszky 1866, Hulják 1942) parts of Slovakia. Neilreich (1866, 1870) summarised the information available till that time on the distribution of S. palustris for the whole territory of historical Austro-Hungary (incl. Slovakia). From the end of World War I to 1970, the distribution of S. palustris in south- ern Slovakia was described by Domin and Podpěra (1928), Hendrych (1963, 1968) and Holub and Moravec (1965) and marginally mentioned in the works of Šomšák (1963), Zahradníková-Rošetzká (1965) and Berta (1970). In the last decade, the research of aquatic and marsh vegetation has be- come a point of interest in most parts of Slovakia (e. g. Kochjarová et al. 2012, Bubíková et al. 2016, and many others). Despite the fact that many regional works deal with aquatic vegetation, the information on the occurrence of Son- chus palustris in natural as well as anthropogenic water habitats are very rare (Balázs 1996, Hrivnák 1999). From the end of 18th till to first quarter of 20th century the data about the distribution of S. palustris were published more or less randomly. Between the years 1960–2005, the published distribution data (and collected herbarium specimens) are more frequent. Exploratory field excursions in southern part of central Slovakia in the basins of Rimava and Slaná Rivers (Kliment et al. 2000, Kochjarová 2010) brought new populations findings. The distribution continues here along the Ipeľ (= Ipoly) and Slaná (= Sajó) rivers to northern and central Hungary, where the species is commonly occurring (cf. Bánkuti and Vojtkó 1995, Bartha et al. 2015, and our observations). In western Slovakia, the occurrence in the Záhorská nížina lowland is tied up to distribution in southern Moravia and eastern Lower Austria. In Moravia, only three areas in the present time around the towns of Hodonín, Mikulov and Tišnov are known (Křísa 2004). Jongepier and Jongepierová (2006) and Perný (2007) mentioned S. palustris from the Biele Karpaty Mts as rare in waterlogged places along streams, mainly in southwestern part of the mountains. However, the detailed extension of the species has not been processed so far in Slovakia. In the latest version of the Slovak red list of ferns and flowering plants of Slovakia (Eliáš et al. 2015) the species is evaluated by the category NT (near threatened).

This paper provides a detailed distribution of Sonchus palustris in Slova- kia, including historical, as well as recently confirmed locations and reassess- ing its conservation status based on field observation. We analysed chromo- some number in material from two localities in Slovakia.

MATERIALS AND METHODS Collecting of distribution data

The study and field research was carried out during the years 2015–2018. The data concerning the distribution of the species were found only in 14 pub- lic herbaria: BP, BRA, BRNU, HLO, KO, LTM, OL, OLM, NI, SAV, SLO, TM, TTM and W. Herbarium acronyms follow Thiers (2019) and Vozárová and Sutorý (2001) for small local collections. The species’ records were collected also from published and unpublished studies and botanical databases (the file database stored in the Plant Science and Biodiversity Centre, Slovak Academy of Sciences, Bratislava, Slovakia; distribution data from habitats and species mapping of Slovakia (Šefferová Stanová et al. 2015; http://www.biomonitor- ing.sk/); the central database of phytosociological relevés (http://ibot.sav.sk/ cdf/)). The distribution map was designed in the program ArcGIS, version 9.2. The mapping grid follows the grid template described by Niklfeld (1971). A list of revised specimens and other records were compiled according to the di- rectives of the work Flóra Slovenska VI/1 (cf. Goliašová and Michalková 2012).

Karyology

For the karyological studies, the seeds of S. palustris were collected at two localities: (1) Šarišská vrchovina hill area, Hendrichovce (col. M. Dudáš in 2016, voucher specimen deposited in KO: 34307) and (2) Spišské kotliny Ba- sins, Domaňovce (col. V. Kolarčik in 2017). The root-tip meristems of germi- nating seeds were used for chromosome counting. Root tips were pre-treated in 0.002 M aqueous solution of 8-hydroxyquinoline (16 hrs at 4 °C), fixed in the mixture of 96% ethanol and 98% acetic acid (3:1 for 1 hr), then washed with distilled water, macerated in 1 M HCl in water bath (60 °C, 5 min) and washed again. The slides were made using the cellophane square method (Murín 1960). The slides were stained by a 7% solution of Giemsa Stain, Modified Solution, Fluka Analytical, in Sörensen phosphate buffer, dried and observed in a drop of immersion oil. For the observation of chromosomes microscope Leica DM 2500 equipped with camera HDCE-X5 and software ScopeImage 9.0 was used.

RESULTS Distribution and ecology

Altogether, we have seen over 90 herbarium specimens and collected at least 30 published and unpublished records not supported by herbarium specimens. Our field research revealed 61 new localities and confirmed at least twelve historical locations. The detailed locations of S. palustris in Slova- kia are reported in the Appendix 1. Sonchus palustris has been found in Slovakia altogether in 19 of total of 31 phytogeographical districts and subdistricts. Seven of them are included in the area of the Pannonian flora province (Pannonicum) and twelve in the area of the Carpathian flora province (Carpaticum).

Karyology

Seedlings from the localities of Hendrichovce and Domaňovce (eastern Slovakia) showed 2n = 2x = 18 as somatic numbers, being one of the pairs sat- ellite in both cases.

DISCUSSION Distribution

As the distribution map (Fig. 1) has shown, most of the species’ locali- ties are situated in the southern part of the country (the Podunajská nížina lowland, the Ipeľsko-rimavská brázda Region, southern parts of the Sloven- ský kras Karst, the Košická kotlina Basin and the Východoslovenská nížina lowland) where the species grows in marshes predominantly along railway embankments, streams, fishponds, canals, mining pit-ponds and alluvial meadows. From lowlands and basins of the Pannonicum province in the southern Slovakia the species has penetrated into the neighbouring Carpathian prov- ince, where it is very rare, but locally it may form abundant populations. In the Carpathian province, S. palustris prefers larger warm valleys and basins at lower altitudes. From these sides it always spreads in ditches and wet places along railway embankments and roads. Isolated occurrence in northeastern Slovakia is represented by small local enclaves. One of them, northern of the village of Domaňovce (Spišské kotliny basins) reaches the altitudinal maxi- mum in 439 m a. s. l. in Slovakia. Historical altitudinal maximum, known at the village of Lipovce at the altitude of ca 530 m (Hendrych 1963) has not been confirmed at the present time by us.

Despite a lack of previous data in other areas, during our field research in southern Slovakia almost continual distribution along the railway embank- ments in line Rožňava – Číž – Jesenské – Hodejov (in length of ca 50–60 km) was found. The plants have always grown here over 3 m high and wind gen- erated by passes of trains significantly contribute to anemochory spreading of the achenes. The railway embankments are associated with many marshes and wet places and this fact supports the spread of the species to further lo- calities along the railways. We noted the species rarely in eastern Lower Austria, mainly along canals, while the most localities were found around the lake Neusiedler See in large areas of Phragmitetum communities in the season of 2018. In the Podunajs­ká nížina lowland, the occurrence is fragmented in small islands, but intensive field study in the future surely brings new population findings. Evident decrease in number of localities was found in the Východoslo­ venská nížina lowland. There were published more than 10 localities of S. palust­ris in the past (Berta 1970, Bogoly 1992, Šomšák 1963). These sites have probably disappeared due to the drainage and riverbed modification of the Latorica River (Šimková et al. 2014). However, we confirmed only two of them (around the town of Kráľovský Chlmec located in oxbow of the Latorica Riv- er) and found only one new (on waterlogging alluvial meadows of the Onda- va River, on an area approximately 1 km2 with thousands of individuals). In Ukraine, the species was recently noted by Woch and Trzcińska-Tacik (2015) in western part of the country located on northern side of the Carpathians Mts, while on the southern side along the Latorica River, there is not known any information about a recent occurrence (V. Sabadosh 2016, pers. comm.), and Chopik and Fedoronchuk (2015) ascribed it as very rare. Isolated occurrence of the species in northeastern Slovakia is represented by three localities. The occurrence in the first locality at the village of Lipovce (Branisko Mts) was given already in the first half of 19th century (Hazslinszky 1847) and it was last time confirmed by Hendrych (1963) around the Salvátor spring. It has not been recently confirmed by us, despite the fact that large area of Phragmitetum community has been growing here until now. In the years 1958–1959 V. Pospíšil collected other Sonchus species here (the speci- mens deposited at BRNM), but his collection does not contain any specimen of S. palustris. The second population was recorded near Domaňovce in an alluvium of the Lodina stream (see also Karyology chapter). The third and most isolated occurrence is represented by a small population south of the town of Bardejov at the Kobyly village. Hazslinszky (1853) published the occurrence “in valleys of the rivers of Poprad and Hornád” (without exact locality). Although some suitable large areas with common reed (Phragmites australis) are present along the Hornád and Svinka Rivers, the occurrence of S. palustris in alluvium of the Poprad River has surely little probability (cf.

Chrtek and Skočdopolová 1986, Mártonfi 1992). Small number of populations in northeastern part of Slovakia follows rare occurrence in southeastern Po- land, where the most of the species distribution is concentrated in northwest- ern and central part of the country (Zając and Zając 2001).

Karyology

The chromosome number 2n = 18 from two locations (Domaňovce, Hen- drichovce) agree with previously published data from western Slovakia (Má- jovský 1976) and as in material of diverse origin as from Europe and Caucasus (Goldblatt and Johnson 2019) and Northern America (Brunton and Cromp- ton 1993). Therefore it seems, there are no different cytotypes at least within the European distribution range of the species. Karyological analysis of both populations further consistently showed, that one chromosome pair is bear- ing chromosome satellite. Presence of 1–3 satellite chromosomes in karyotype of Sonchus species with 2n = 18 is very common, which may or may not be of taxonomic relevance in particular groups (Mejías and Andrés 2004; Mejías et al. 2012, 2018).

Conservation status

In the last version of the Slovak red list (Eliáš et al. 2015) the species is evalu- ated as near threatened (NT). Considering the common occurrence of this spe- cies in southern Slovakia, conservation status should be reconsidered. On the other hand, although S. palustris is quite common in some regions of Slovakia, its occurrence has declined significantly or the populations have become restricted to small number of individuals in some cases. Probably, the distribution range of S. palustris in Slovakia was underestimated in the past, which led to the over- estimation of the species threat. Methodologically rigorous mapping and demo- graphic analyses for the area required to the accurate evaluation of their conser- vation status (Jensen and Meilby 2012, U.S. Fish and Wildlife Service 2011). Curiously, the species is evaluated as “rare” with category C2b in the Czech Republic (Grulich 2012), while it is protected but not considered to be endangered in Hungary (Király 2007). Finally, S. palustris is ranked in the LC category (least concern) in the global IUCN red list of threatened species. It is widespread with stable populations and does not face any major threats (Lansdown 2014).
