Data S1. IMa2 commands.

Fig. S1 Mean and SD of model likelihood from 20 STRUCTURE runs. The data excluded SNPs in the upper 5% tail of the FST distribution.

Fig. S2 Mean and SD of model likelihood from 20 STRUCTURE runs based on 36 SNPs in the upper 5% tail of the FST distribution.

Fig. S3 Ancestry proportions, based on 1808 SNPs (one SNP randomly selected per reference contig), assuming 2, 3 and 4 groups. The first 20 samples are from Great Sand Dunes National Park and Preserve, followed by 10 H. petiolaris from outside the park (abbreviations as in Fig. 3) and 10 H. annuus individuals from across its range.

Fig. S4 (a) Ancestry proportions, based on 1772 SNPs (one SNP randomly selected per reference contig and excluding the upper 2% tail of the FST distribution), assuming 2, 3 and 4 groups. The first 20 samples are from Great Sand Dunes National Park and Preserve, followed by 10 H. petiolaris from outside the park (abbreviations as in Fig. 3) and 10 H. annuus individuals from across its range. (b) Ancestry proportions, based on 36 SNPs representing the upper 2% tail of the FST distribution, assuming 2 or 3 groups.

Fig. S5 Hybrid indices of dune individuals, testing H. annuus ancestry with reference to the non-dune form. (a) Putatively neutral SNP loci. (b) SNPs with in the upper 5% tail of the dune/non-dune FST distribution. Grey vertical bars group individuals by subpopulation.

Fig. S6 Hybrid indices of dune individuals, estimating the contribution of H. petiolaris from outside the San Luis Valley to the ancestry of the dune (a) and non-dune (b) forms with reference to the non-dune forms, respectively. Grey vertical bars group individuals by subpopulation.
