Phylogeny and the species delimitation of Ranunclus section Batrachium (Ranunculaceae).

Section Batrachium (Water Crowfoots) is a monophyletic group of macrophytes classified within cosmopolitan, morphologically, and ecologically diverse genus Ranunculus (Ranunculaceae). Batrachium is regarded as taxonomically the most challenging groups of plants because of an extreme phenotypic plasticity, frequent hybridization and introgression, allo- and autopolyploidization, and persistence of genetically independent, sterile lineages. Only recently, thanks to the application of the molecular tools, the modern Batrachium phylogeny starts to clarify. Based on the direct sequencing of selected DNA regions (ITS and cpDNA) some Batrachium taxa were successfully molecularly characterised and general phylogenetic clades were resolved. However, molecular studies revealed also significant intraspecific genetic variation within Ranunculus trichophyllus, not directly related with morphological characters, as well as a genetic split in R. baudotii between populations from coastal regions of the Baltic Sea basin and those dispersed though the inland Europe. During presentation, the main clades of Batrachium will be presented and the complex pattern of Batrachium diversity, with well-defined species, polyploids, cryptic species and hybrids will be discussed.
