Phylogeny of Isoetes (Isoetaceae). Maximum likelihood analysis of plastid (ndhC-ndhK, rbcL, rpoC1, ycf1, ycf66, and trnVUAC and its subsequent spacer) and nuclear ribosomal data (nrITS), but excluding nrITS data from outgroups and Isoetes wormaldii because of potential problems to infer positional homology (but see also Additional file 1: Fig. S3). Bootstrap support values and Bayesian posterior probabilities (as estimated in a separate analysis in MrBayes) are indicated on the tree as follows: maximum likelihood bootstrap / Bayesian posterior probability. Clade names A–E and their respective subclades are discussed in the text. Geographic distribution of species are indicated in color according to the legend to the left and following the World Geographical Scheme for Recording Plant Distributions [45]. An exception is the Mediterranean distribution, which refers to an occurrence in either one of the 22 sovereign countries in Europe, Africa and Temperate Asia that borders the Mediterranean Sea. Collection localities (country, and state for USA, Canada and Australia) of investigated samples are indicated in parenthesis to the right of the taxon names
