Anonaceae, Artabotrys hexapetalus, Ylang-Ylang vine

I got seed from a good friend of mine, the only other person I know who has this species. He mentioned something about it being the true Cananga odorata (Ylang-Ylang). I have found it identified as Artabotrys hexapetalus, originating in India. The plant grows like a sprawling shrub that will turn in to a vine if it is given a support structure. I planted this one next to an Orchid tree and a grafted Rambutan and it has effectively grown up into each of them. Although not apparent in the photos, the branches have hook-like protrusions (like Una de Gato, less sharp). These aid the sprawling branches in climbing. 

I am interested in getting a positive ID on this one and any other significant information. No flower photos at this point.

I currently have a large batch of seeds germinating.
