Excercise on leaves

Mille de fleur is over. You remember? Last year was my favourite year. All the fashion with the little flowers. You maybe will not understand my weakness for them without further explanation: When I was a little child we had a wallpaper with a highly ordered green flower-and-leaves pattern in my room. A relict of the seventies. Note that they were ORDERED!

 

Are there ways to describe dendritic growth?

 

(Yes, sure.)
