If you want to sing it as the Carter's did it in 1927,you'll use the lyrics Gene gave. Maybelle herself gives different lyrics in the 50's. So it probably doesn't matter what really are the lyrics or trying to find some "orginal" "first" lyrics. I would suggest that any version you find is just one that someone heard. The version the Carters did probably came from the palor song of 1859 I'll Twine Midst the Ringlets by J. Webster. Another possible source of the Carter tune was The Pale Amaryliis. They themselves couldn't give the exact meaning of the phrase. So if you are looking for the meaning emanita or aronatus, you may looking for some flower or whatever that someone only guessing at when he/she sung and wrote down.
