Arboricola leaves are thicker, actinophylla leaves are as thin as most tree leaves generally. Arboricola leaves tend to grow out from the stem in the same direction as the stem, actinophylla leaves array out perpendicular to a central point on the end of the stem.
But those aren't always 100% true, sometimes there can be grey areas and similarities in younger trees.
You can crush a leaf in your hand and if it has a slight black pepper smell it's Arboricola.
