“…Although hybrids in Potamogetonaceae were first recognized already in the late 19th century (see for a brief review), molecular evidence became available only during the past decades by using isozyme electrophoresis (e.g., Hollingsworth & al., 1995;Fant & al., 2001;Iida & Kadono, 2002;Kaplan & al., 2002;Kaplan & Wolff, 2004;Kaplan, 2007;Bobrov & Sinjushin, 2008) and DNA-based techniques (e.g., King & al., 2001;Fant & al., 2003;Kaplan & Fehrer, 2004, 2009Ito & al., 2007Ito & al., , 2014Du & al., 2009Du & al., , 2010Les & al., 2009;Zalewska-Gałosz & al., 2009, 2010Aykurt & al., 2017;Iida & al., 2018). While these studies focused on hybrids, a few of them performed also phylogenetic analyses (e.g., Les & al., 2009;Ito & al., 2014;Zalewska-Gałosz & al., 2018), but these include only taxa relevant for the identification of hybrids. Several studies focused on the phylogeny of Potamogetonaceae (Iida & al., 2004;Lindqvist & al., 2006;Wang & al., 2007;Zhang & al., 2008;Ito & Tanaka, 2013).…”

The family Potamogetonaceae has been taxonomically re-evaluated in Turkey, employing traditional morphological as well as molecular approaches (rbcL, ITS). Our fieldwork, herbarium studies and molecular analyses proved the existence of 22 taxa, of which 18 belong to Potamogeton (including 4 interspecific hybrids), 3 to Stuckenia and 1 to monotypic Groenlandia. Morphological re-descriptions of the recognized taxa were prepared, and the information concerning their distribution in Turkey was refined, based on plant material from extensive fieldwork and on specimens stored in herbaria that were previously not examined. Additionally, new identification keys to genera and species, and distribution maps of the species were prepared. Phylogenetic relationships and intraspecific variations were assessed by including samples from other regions. The status of the Zannichelliaceae was investigated using nuclear and chloroplast DNA markers. Our results from ITS sequence divergence corroborate the separation of the two families noted by some authors, and are in accordance with the substantial morphological differences between them. Relatively large genetic distance and non-monophyly indicate that two genotypes of P. gramineus constitute cryptic species, for which the Turkish localities expand upon the previously known distribution areas. We identified P. schweinfurthii as a new species for Turkey and report P. ×angustifolius for the first time for this country. Weak morphological differentiation and high sequence similarity did not permit reliable differentiation between the closely related Stuckenia amblyphylla and S. filiformis.

“…However, only the application of isozyme electrophoresis (Hollingsworth et al 1995;Fant et al 2001a, b;Kaplan et al 2002;Kaplan and Wolff 2004) and DNA-based techniques (Kaplan and Fehrer 2004Ito et al 2007;Du et al 2009;Zalewska-Gałosz et al 2009) provided unequivocal evidence for the existence of many of the hybrids. In addition, molecular analyses have recently provided insight into the previously unknown parentage of several hybrids Zalewska-Gałosz et al 2018), contributed to the discovery of several entirely new hybrid combinations (Kaplan et al , 2018Zalewska-Gałosz et al 2010;Bobrov et al 2013) and even confirmed the existence of a natural triple hybrid (Kaplan and Fehrer 2007).…”

e interspeci c hybrid Potamogeton ×salicifolius (= P. lucens × P. perfoliatus), so far known only from several countries of Europe and a few countries of Asia, was discovered in Western Australia. Morphology of the Australian specimens ts the range of variation observed in Eurasian specimens. DNA sequencing con rmed the morphological identi cation as a hybrid P. lucens × P. perfoliatus, and identi ed P. lucens as the maternal parent. is identity is surprising because neither of the parental species are known to occur in Western Australia and P. lucens currently does not even occur in the continent. ree possible explanations for the occurrence of P. ×salicifolius in Western Australia are discussed: its relictual occurrence from a time when both the parental species occurred there, long-distance dispersal of a hybrid seed from Eurasia and the remnant of local cultivation or intentional planting.
