New floristic records from Central Europe 4 (reports 41–53)

Abstract

The fourth part of the series includes 13 new chorological records of vascular plants from Poland and Slovakia. From Poland, the first record of Rubus austroslovacus from the Vistula River valley is given as well as the first record of Erigeron ×huelsenii from Silesia. Beside this, spontaneous occurrence of Portulaca grandiflora in Kraków and P. oleracea subsp. oleracea in Suwałki has been recorded outside the cultivation. In Slovakia, new sites of endangered species Dichostylis micheliana and Stipa pulcherrima were found as well as new distribution data about Sonchus palustris and Reynoutria japonica. From railway stations, Tribulus terrestris is reported for the first time from eastern Slovakia likewise two new sites of alien species Euphorbia davidii, previously reported from only single locality in southeastern Slovakia. Alien species Xanthium spinosum was reported from the Štiavnické vrchy Mts. and also Sisyrinchium montanum in the Slanské vrchy Mts. Third report of Sagittaria latifolia in Slovakia is given with short characteristic of its coenological conditions.

Taxonomical and chorological notes 17 (178–183)

“…In this vegetation unit C. michelianus dominated, with presence of exposed bottom and marshy species such as Amaranthus blitum, Bidens fr ondosus, Butomus umbellatus, Cyperus fuscus, Echinochloa crus-galli, Chenopodium polyspermum, C. rubrum, Portulaca oleracea and Sagittaria sagittifolia. Th e species is likely more frequent on upper parts of Bodrog and Tisza rivers, which also confi rms reported localities from the Slovakian side of the Bodrog river net (Dítětová et al 2016, Dudáš et al 2019.…”

“…Tragus śródziemnomorski preferuje gleby piaszczyste i kamieniste, kwaśne lub zasadowe, suche i ubogie w składniki odżywcze. Często występuje jako chwast na pastwiskach i przydrożach (Dudáš et al, 2018;Hyde et al, 2022;Kaplan et al, 2015;Lazkov & Sennikov, 2014;Sulekic & Zapater, 2001). Dzięki hakowato zakończonym wyrostkom na plewach górnych roślina jest łatwo rozsiewana przez zwierzęta (epizoochoria), zwłaszcza owce (Lazkov & Sennikov, 2014), przez co do niektórych krajów została zawleczona razem z importowaną wełną (Kaplan et al, 2015).…”

Overview of the floristic and taxonomic studies on Iridaceae Juss. in Bulgaria

“…Sisyrinchium montanum Greene has been referred to Balkan flora as a North American adventive species, localized in Romania in 1943 (Popescu & Boruz 2008), later on in Serbia (Ranđelović et al 2010) and Bosnia and Herzegovina (Milanović et al 2018). Data on the adventitious distribution of this species are also known in other countries of Europe (Ingram 1980;Kaplan et al 2016;Dudáš et al 2019). The species has been reported as new for the flora of Bulgaria for the first time by Kolev (1972) under the name S. angustifolium Mill.…”
