FIGURE 3 in Seed morphology of Portulaca (Portulacaceae) in Cuba and taxonomic implications

FIGURE 3. Variation of length/width ratio and shape 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.
