FIGURE 2. Variation of length (A) and width (B) of Portulaca seeds in Cuba. For each species in a boxplot the mean, the 95% confidence intervals (estimated by Monte Carlo using 10,000 randomizations) and the 95% range for the central data are presented; to the left of the boxplot the point cloud is shown and to the right its density curve. Different letters represent statistically significant differences between species.
