The Osage Orange or Maclura-Pomifera

This is a tree from North America called the Osage Orange or Maclura-Pomifera. They look as if they're like little fingers with tiny nails on them. But this is how these plant distributes its seeds. So these little orange like almost pustules are actually the seeds. It's getting worse. And birds come along and eat these, which are quite sweet but bonkers to look at.
