Figure 2. Violin plots with Bonferroni pairwise comparisons showing the differences in morphological features between the three elevation zones in LNP and SNP. Within three elevation zones in LNP and SNP, features that do not share the same alphabet have significantly different values (p < .05). See Supplement 4 for details of statistical analyses.

Figure 3. Transverse sections of a (A), (C) basal stem and (B), (D) ultimate branch collected from LNP (A and B, sample LC10) and SNP (C and D, sample SN6). V = xylem vessel, R = ray parenchyma, FT = fiber tracheid, RB = growth ring boundary, and P = pith.

Figure 7. Violin plots with Bonferroni pairwise comparisons showing the variation in anatomical features of the ultimate branch in three elevation zones of LNP and SNP. Different elevations that do not share the same alphabet within LNP and SNP have significantly different values (p < .05). See Supplements 7 and 8 for details of statistical analyses.
