Figure 5.

Tree summarizing the placement of the polyploid allele origins from the Iopetala group on the backbone diploid species tree. Origin placements with bootstrap support over 70% for one or more alleles are displayed, as in Figure‚ÄČ2. Tips named S. hougasii represent 4 of the S. hougasii accessions with similar results (161174, 161726, 558402, 558422). Similarly, tips marked S. iopetalum represent 5 of the S. iopetalum accessions (275181, 498021, 498251, 558405, 558409) and tips marked S. schenckii represent 3 of the S. schenckii accessions (275261, 498040, 498250).
