Standard diameters of round flowers

The willow is a modified form of a round flower. The only difference between the two is that the willow has a vertically symmetrical axis and appears most clearly in the configuration when we see it at right 

We have other varied irregular forms other than the round and willow but generally they have no artistic centre.
