The volume was named after the waka (a traditional Japanese poem of thirty-one syllables) composed by Ochiba no miya, the widow of Kashiwagi (see below) in the story: Although the god of leaves is not in Kashiwagi, is it appropriate to allow people to come closer to the treetop without reason?
巻名は作中で柏木（下記）の未亡人落葉の宮が詠む和歌「柏木に葉守の神はまさずとも人ならすべき宿の梢か」に因む。
