  1. Sample sizes (N f: number of families, N i: number individuals), means and standard errors (SE) or 95% confidence intervals (CI) are presented. Patches are classified from the smallest (Patch 1) to the largest patch floral display (Patch 28). Four patches had a small number of individuals (N i), resulting in an irregular bootstrap distribution of F estimates. The estimates of F and ID for these four patches are, therefore, not presented (-). See the Method section for lifetime inbreeding depression calculation.
  2. Abbreviations: t m: multilocus patch outcrossing rates, s m: multilocus patch selfing rates (sm =1 - tm); Nf: number of families; SE: Standard errors; Ni: number of individuals; CI: confidence interval; ID: inbreeding depression; a: patch selfing rate not significantly different from 0 based on 95% confidence intervals. b: F significantly higher than zero (more homozygotes than expected at Hardy–Weinberg equilibrium) based on 95% confidence limits. c: bootstrap distribution of ID values significantly different from 1. d: bootstrap distribution of ID values significantly lower than 0. All other patches had ID values significantly higher than 1.
