Figure 4. NeighborNet analysis of cloned ITS1+ITS2 variants.
Particular clones belong to: Ranunculus cassubicifolius (“S”-clones), R. notabilis (“N”-clones), their synthetic hybrid (“X”-clones) and the putative hybrid, R. variabilis (“V”-clones). The spring leaf silhouettes illustrate the main phenotypic difference between the auricomus and the cassubicus morphotypes. Italic letters mark clones which exhibit non-compensatory base changes in the ITS1 or ITS2 secondary structures. Bootstrap values are given for the main clusters.
