What is a palmate leaf arrangement?

In palmately compound leaves, the leaflets form and radiate from a single point of attachment called the distal end of the petiole or rachis. Another way to describe the palmate form is that the whole leaf structure is “palm-like” and shaped like the palm and fingers of your hand.

What does palmate and pinnate mean?

What are pinnate veins?
