Distributions of vascular plants in the Czech Republic

“…Husák et al 1988). Because of frequent misidentifications, the distribution map of this species is based solely on examined herbarium specimens and on plants examined using flow cytometry (Prančl et al 2018).…”

“…It is classified as critically endangered (Grulich 2012). The map is based solely on examined herbarium specimens and on fresh plants examined by flow cytometry (Prančl et al 2018).…”

“…Maps resulting from studies on Ranunculus sect. Batrachium (Prančl et al 2018), Diphasiastrum (Hanušová et al 2014) and Orobanche (Zázvorka 2010) are included in this paper. Another genus with species difficult to identify is Carex, which is represented here by ten species.…”

Discovery of the Northern Hemisphere hybrid Potamogeton ×salicifolius in the Pilbara region of Western Australia

“…e taxonomic complexity of aquatic plants is o en further increased by interspeci c hybridization (Cook 1970;Les and Philbrick 1993;Moody and Les 2007). is makes their taxonomy di cult because species o en cannot be easily sorted based on morphology (Kaplan and Symoens 2005;Kaplan 2008;Moody and Les 2010;Kaplan and Marhold 2012;Kabátová et al 2014;Prančl et al 2014Prančl et al , 2018. e cosmopolitan genus Potamogeton L. (Potamogetonaceae) has the highest species diversity among all aquatic plants (Wiegleb and Kaplan 1998).…”

Evolutionary history and genetic diversity of apomictic allopolyploids in Hieracium s.str.: morphological versus genomic features

“…Cytogenetic investigations (genomic– and fluorescence in situ hybridization [GISH and FISH]) are powerful tools in verifying the origin of polyploid taxa, as well as the genome dosage of the respective parents (Heslop–Harrison and Schwarzacher, ). Genome size is usually stable within morphologically defined species and often differs even between closely related species (e.g., Bräutigam and Bräutigam, ; Prančl et al., ; Róis et al., ; Zahradníček et al., ). This may help resolving conflicting hypotheses about the origin of polyploids (auto– vs. allopolyploidy) and identifying putative parental combinations in hybridogenous species (e.g., Mahelka et al., ).…”
