At some point I looked this carol up, and found references to the earliest known telling of this set of miracles, in about the fifth century, in one of the books of the apocrypha, which told the story as being a palm tree, during the flight into Egypt. Fast forward to fifteenth century England (or sometime thereabouts), when the palm tree had become our cherry tree in the ancestor of this carol.

Now, the trouble is that I have lost track of where I found this information, and I'd like to check what that source said. Does anyone know what I'm talking about here, or have ideas about how to direct me?
