I think it is how the veins are formed, for example: Pinnate venation has one main vain going through the leaf, and other veins branching out. There is also palmate, parallel, and netted. Hope I helped!
Moonbeam leaves, which belong to the Astilbe plant family, are not parallel. Instead, they typically exhibit a feathery, fern-like structure with pinnate or compound arrangements. The leaflets are arranged in a way that creates a more intricate pattern rather than the simple parallel venation seen in some other plant species.
A palmate leaf.
If L1 is parallel to L2 and L2 is parallel to L3 then L1 is parallel to L3.
A structure that is parallel.

When you look at the image of a Sassafras leaf, would you say that it is shaped more like the palm of your hand (palmate), or is it shaped more like a feather (pinnate)? If you Google "Sassafras image", you can answer the question yourself.
The venation of a cottonwood leaf is typically palmate, with several primary veins radiating outward from a central point at the base of the leaf. This venation pattern helps distribute water and nutrients efficiently throughout the leaf.
