Poly blooms are so interesting! If I'm not mistaken, they will have the same number of extra stamens/anthers as they have extra tepals, so a 4x4 would have 8 anthers, and a 5x5 would have 10. Here's some from my garden.
'Emerald Dream'
'Jedi Spring Charm'
'Big City Eye'
'Orange Velvet'
'Bela Lugosi'
