Leaf Margins: Undulate

Waves in leaf margin (if margins have more sever waves see: sinuate) that give more 3-dimensionality to the margin of the leaf. This characteristic can make a leaf hard to flatten or press.

This is not easy to display in leaf collections, but it is easy to see on a live sample.
