Tm does not correlate with cell orientation, time of last division, or area. We looked for correlations between tm and cell orientation (A and D), time of last division (B and E), and ln(area) (C and F) for real (blue) and spatially averaged (red) cell lineages of flowers A (A–C) and B (D–F). The cell orientation is measured as the angle (radians) between the main sepal axis and the main axis of each cell. The time of last division is indicative of whether the cell lineage is actively dividing (late time of last division) or endoreduplicating (early time of last division). We take the logarithm of the cell area to avoid spreading out. Both the area and the angle are measured at the reference time point.
