图2 辐射对称与两侧对称物种花大小变异的系统发育独立比较。共6个分类组, 每一组包括两侧对称和辐射对称的物种对, 分别估计变异系数的平均值, 然后对6组值进行非参数检验: Mann-Whitney U, Z = - 0.964, p = 0.394。

Fig. 2 Pairwise phylogenetic comparisons of flower size in bilaterally and radially symmetrical species. The paired points represent family means or means of higher taxonomic groups for six independent cases where the phylogeny branches dichotomously into a bilateral and radial pair. A non-parametric test was used to examine the differences in mean coefficient of variation (CV) of the six pairs, Mann-Whitney U, Z = - 0.964, p = 0.394.
