What is the geometric pattern on an osage orange or hedge apple?

The hamsters wanted some fruit and ate the post. It’s not only squirrels liking the seeds. :slight_smile: I’ll work from the title.

Two nice big pictures for those like me who have never seen it before.

It’s an aggregate fruit, made from smaller parts that grew together. Here’s a page with a picture of its flowers: http://www.extension.iastate.edu/pages/tree/osage-or.html
