Phylogenetic inference and genetic structure. (a) Floral morphology of two species pairs (Eastern species pair and Western species pair). (b) The Maximum Likelihood (ML) phylogenetic tree of 158 individuals of A. kansuensis and A. ecalcarata. (c) Results from ADMIXTURE with K = 2, 3, 4, 5 based on SNP data. (d) The first two dimensions of principal component analysis (PCA) based on SNP data. (e) Geographic distribution of the sampling locations. The colors represent ancestral genetic components (according to ADMIXTURE at K = 4)
