Phylogenetics and phylogeography of the monocot genus Baldellia (Alismataceae): Mediterranean refugia, suture zones and implications for conservation

► The monophyly of the genus Baldellia is strongly supported. ► Confirmation of the genetic distinctness of Baldellia repens. ► Glacial refugia located in the Iberian Peninsula and the Italy/Balkan region. ► Large suture zones in northwestern Europe. ► Conservation approaches should always include phylogeographic surveys.
