Table 1. Differences in Intercalary Leaflet Count between the Ascending and Descending Sides of the Leaf.

Side of the Leaf	Mean Intercalary Leaflet Count	se
Ascending	3.28	0.07
Descending	3.65	0.07

Shown are the mean intercalary leaflet counts on the ascending and descending sides of the fourth leaf. There is a highly significant increase in leaflet count on the descending side of the leaf relative to the ascending side (∼0.37 leaflets), consistent with previous studies (Koenig et al., 2009), and observations of increased auxin response on the descending side of primordia. n = 392; P = 3.12 × 10⁻¹¹ (Wilcoxon paired),
