Numerical analysis of infraspecific variation in European Silene alba and S. dioica (Caryophyllaceae)
Infraspecific variation among European populations of Silene alba and S. dioica was analysed by non‐metric multidimensional scaling, which was applied to K‐dissimilarity matrices based either on 16 seed characters or on 34 seed, flower and capsule characters. The material used for analysis consisted of 167 collections of wild seed, largely obtained from European botanic gardens, and 97 sets of mat
