  1. Values are the percentage of variation at each hierarchical level. Plants were sampled from two plots (~20 plants per plot) within each of seven outcrops. Each flower was measured twice to estimate measurement error. Statistical significance of the variance components is indicated as: *P < 0.05, **P < 0.001. Note that the variance among plants within plots for the assignment probability cannot be tested for significance because individuals served as the basic unit of analysis
