I have the book: Fruit, Berry and Nut Inventory. Third Edition.

In the section on plums, the following varieties are listed (among many):

Methley - self-fruitful
Opal - self-fertile
Stanley - self-fertile
Sugar Prune - self-fruitful
Yellow Egg - self-pollinating

I know that all the 'self-fertiles' will produce more fruit if cross 
pollinated.

What is the difference between 'self-fertile', 'self-fruitful', and 
'self-pollinating'?
