Hmmm...looks like tip 101 or 103 done kinda like the rose, just more petals? I'll have to look again, it might be done backward (bottom petals first).
Edited to add: nope, not backward.
That looks a lot like a rose to me. I grow peonies in my garden and they all have the center in them. In the May June issue of Decorated Cakes by Marcela Sanchez there are instructions on making the gumpaste peony. It is really pretty.
