FIGURE 2. Box plots of the comparison of characters between Ilex fargesii and I. micropyrena (A), and the two subspecies of I. fargesii (B1–B5). A, rachis length. B1, leaf length; B2, leaf width; B3, ratio of leaf length/width; B4, length of leaf pedicel; B5, rachis length. The boxes (rectangle region) represent the interquartile range and the whiskers (vertical line) represent the range excluding the outliers (circles). The upper, middle and lower lines on the boxes represent the 75%, 50% and 25% of the variables, respectively. The upper and lower ends of the whiskers represent the maximum and minimum values of the variable, respectively. The circles represent the single value, where the variable value exceeds 1.5 times the difference between the 75% and 25%.
