   A friend has a wild pear (pyrus spp.) that bears inedible fruit.  To 
help him out, I grafted scionwood from my pears onto his wild pear.  His 
tree accepted all of my grafts.  Several of those grafts were from my Ure 
Pear.  When I saw the abundance of edible fruit on his tree, I grafted his 
wild pear scionwood onto my Ure but the Ure rejected all grafts.  That is 
curious:  How can scions be accepted onto a tree whose scions are rejected 
by the other?  I guess that is one of the mysteries of Nature.
