What would this comb be called?

[BeerCanChikCoop]

Here is one of our babies from this spring. We ended up with two that have this type of comb and are wondering what it would be called.
The eggs were from a coop that contains Rhode Island Red hens, Buff Orpington Hens, Barred Rock Hens and a Black Cochin Rooster (most likely) and a Crested Polish (less likely as he was moved to another coop approx a week before the eggs were collected)
Anyone else have interesting combs? Pictures a plus!!

Looks like a buttercup comb, only maybe a little rounder.

Beautiful bird!
