Method S1 Supplementary methods and results of testing the instantaneous expansion model of Picea purpurea and estimating the parameters of a second contact model between Plikiangensis and Pwilsonii.

Fig. S1 Diagrams showing the optimal number of groups (K) obtained by structure across Picea schrenkiana, Ppurpurea, Plikiangensis and Pwilsonii.

Fig. S2 Results of a neutrality test using MFDM.

Fig. S3 Networks of haplotypes or alleles at nuclear loci of Picea purpurea.

Fig. S4 Diagram for inferring the optimal K obtained by structure across Picea purpurea, Plikiangensis and Pwilsonii using ΔK statistic of Evanno et al. (2005).

Fig. S5 Posterior distributions (red lines) estimated using ABCtoolbox based on the nuclear multilocus sequence data and prior (black lines) for all parameters in the hybrid speciation model.
