Cluster networks for dataset 8, constructed using all fragments passing the SH test against 100 random trees. The percent indicates the minimum support required for a cluster to be included in the procedure for identifying putative hybridizations. (a) 15. (b) 20. (c) 30. (d) 40. (e) 50%. The asterisk indicates a potential hybridization event leading to formation of tetraploid F. moupinensis at the highest confidence level. Networks for all datasets appear in Additional file 4: Figure S7
