That is an interesting looking crown! I read that you can cut a regular single crown into 4 sections to get more plants off of it.
Did you do anything to promote fruiting? I have one sugarloaf I got off of ebay last winter. It's in a pot and so far has been a real slow grower.
If you scroll about half way down this website there's a great drawing of a plant that has all the parts labeled. There's so much information here that I haven't even gotten all the way through it.
