More Norfolk Island Pine trees

They are on our flag, we see them every day, but do we really see them?
Norfolk Island pine trees (Araucaria heterophylla) 

If we look closely and they are all very different including how many arms on the top of each green star.

I have yet to receive an explanation why... I really don't need one, just enjoy.

I have been fascinated by these green stars for many years now.
