Table 1. Nine species classification models compared for marginal likelihoods.

Model	Species delimitation	Number of included species
1	EWSI	(1 species)
2	EW+S+I	(3 species)
3	E+W+S+I	(4 species)
4	E+W+SI	(3 species)
5	E+WSI	(2 species)
6	ESI+W	(2 species)
7	EW+SI	(2 species)
8	EWI+S	(2 species)
9	EWS+I	(2 species)

Each model represents a possible relationship for Silene sect. Cryptoneurae with varying number of species. Abbreviations correspond to S. ertekinii (E), S. cryptoneura (W), S. salamandra (S), and S. insularis (I).
