Molecular genetic diversity and structure of rare and widespread Boechera species. The mean statistical value (+/‐ the standard deviation of 1000 bootstraps) is reported. Grey bars indicate widespread species, while white bars indicate rare species. Species are indicated by either empty (B. vivariensis, B. spatifolia), or cross‐hatched fill (B. crandallii, B. stricta). Other figures follow this labeling pattern.
