Relationships between genome size and anatomical traits: (a) lg, (b) Ds, and (c) Dv. In all panels, insets show log-log relationships and R2 values are from standard major axis regressions (lg n = 242; Ds n = 247; Dv n = 198). Phylogenetically corrected major axis regressions have similar slopes, R2, and p-values, and are shown in Table 1. Data can be found in S1 Data. Ds, stomatal density; Dv, leaf vein density; lg, guard cell length.
