Linear regression analysis of correlation between leaf traits for B. calthifolia and elevation based on 258 specimens. (a): leaf length (cm), (b): number of teeth, (c): leaf width (cm), (d): perimeter (cm), (e): leaf shape (represented by ratio of leaf length to leaf width), (f): tooth density (calculated by number of teeth divided by perimeter), (g): leaf area (cm2), (h): petiole length (cm). The numbers in the left upper corner are correlation coefficient (r), with its significance (P-value), between each trait and elevation. The red font represents significantly strong correlation (|r| > 0.3 and P-value < 0.01)
