I am not aware of Annonas being polyembrionic, certainly not any of the common ones I have grown from seed.
Syzygiums are polyembrionic, or I should say at least some Syzygiums are polyembrionic. Syzygium is a large genus.
Citrus are also polyembrionic, again for the most part. Pomelos are not. Key limes produce two identical clones. The rest are usually cited as being triploid, but I once had a Moro blood orange seed send out eight seedlings.
