Ibis & Alice, they are definitely poor V grafts, but this type of grafting procedure does not ever produce the nicest looking trees. Looks to me that the grafting party used very large (wide) branches and root stock which resulted in coarse Union.
I have heard of people shaving the trunk down, but I have not tried it or know a great deal about this, so I would not try.
At least you both rescued and are giving them good care now. Hopefully their blooms will make up the lack of stem appearance.
