I received the following from an author in New Zealand. Maybe some of you can

I am a New Zealand novelist and my third novel is
about to be published. In it I refer to a graft hybrid citrus
tree created by one of my characters, an American
orange-grower of the 1890s. He creates a tree that
produces both oranges and lemons. I am very much
hoping you might be able to tell me whether, in theory,
this is possible!
