Green Sapote Surpise

There have been buds maturing on my Pouteria viridis (green sapote) for many weeks now and I have no idea what they look like before they open. My Pouteria hypoglauca (cinnamon apple) has a bunch of tiny blossoms that are between the leaves and opening in clusters, but the green sapote has pairs of much larger buds. Now there are little proboscis structures emerging from the center. The morphology has me very confused, I guess I'll keep waiting to see what happens if they don't abort.
