Taraxacum Sect. Erythrosperma in Slovakia Iii: Taraxacum Parnassicum Dahlst., New Localities and Notes on Its Distribution and Taxonomy

Abstract

The paper presents new records of Taraxacum parnassicum, the most common member of Taraxacum section Erythrosperma in Slovakia. The species has been recorded in most of the 31 phytogeographical districts of Slovakia. At least 25 new localities were discovered, and many old ones were confirmed. T. parnassicum prefers natural and semi-ruderal sites on limestone, rarely on volcanic and sandy soils, predominantly not shaded. The majority of populations occur from the lowland to supracolline vegetation belt, mainly at elevations of 140–700 m a.s.l., with the altitudinal maximum at 1,410 m a.s.l. A distribution map is given with the list of localities from the whole territory of Slovakia as well as short discussion about its taxonomy and ploidy level.

Taxonomy and distribution of Taraxacum sect. Erythrosperma (Asteraceae) in Poland

“…Distribution data of species from the Taraxacum sect. Erythrosperma were obtained from herbarium collections, published taxonomic studies (Uhlemann 2003;Vašut 2003;Schmid et al 2004;Vašut et al 2005;Dudáš 2014Dudáš , 2018Zámečník 2016;Dudáš et al 2020;Nobis et al 2020b;Dudáš and Vašut 2022), and our herbarium materials collected in the field. Since the studied species are a group of critical, morphologically similar taxa, we decided not to use data from available online databases.…”
