The basic pattern of these stories goes like this:
Young man gets three fruits or plants containing young women.
Young man releases women by cutting fruit, but fails to provide water for first two.
Young man leaves young woman in tree while he prepares for wedding.
False bride turns true bride into animal or plant.
Young man returns and marries false bride.
True bride tries to get attention of young man in whatever nonhuman form she's in.
True bride (in many versions) moves in with a woman.
True bride manages to get attention of young man
False bride is removed; true bride moves in.
There is considerable variation among versions. For instance, the young lord in The Young Lord and the Cucumber Girl has to go on a long quest, get milk for a lion, meat for a tiger, chewing gum for a witch, drink from a blood-and-pus fountain, and slip past giants to get 3 cucumbers from a giantess. In contrast, the prince in The Princess of the Third Pumpkin had only to get up at dawn, put on his coat, and take a bottle of water to his parents' garden, where three pumpkins are growing on one vine.
The Enchanted Flower, page 81, is like the continuation of the Apollo and Daphne story. It begins with a flower that used to be a woman who didn't want to marry the Count of Lauenburg. She avoids him by turning into a white flower. The tale deals with how the flower becomes a woman again: the right person has to pluck her. In this case, the right person is a young woman about to be married.
This week's Google book is Tales and Traditions of the Eskimo containing the story The Blind Man who Recovered His Sight. A cruel mother blinds her son--the son recovers his sight--the son and daughter kill the mother--there are consequences for matricide.
