What trees are there in the white boat?

The Little White Boat is a very classic nursery rhyme.

The lyrics of "Little White Boat" are like this: "In the blue sky and the Milky Way, there is a little white boat; There are osmanthus trees on the boat, and the white rabbit is playing; The paddle is invisible, and there is no sail on the ship; Gone with the wind, gone with the wind, gone with the wind to the west.
