The number of leaves or flowers measured of each species, and the Kolmogorov-Smirnov statistic comparing L*, a* and b* distributions with a Gaussian distribution modelled from the mean and standard deviation are also shown. ** the null hypothesis that the actual and modelled distributions are the same is not supported at P<0.05.
