The Roman History · Amm. 24.3.13

They say further that the female trees produce fruit when impregnated by the seeds of the male trees, and even that they feel delight in their mutual love: and that this is clearly shown by the fact that they lean towards one another, and cannot be bent back even by strong winds—and if by any unusual accident a female tree is not impregnated by the male seed, it produces nothing but imperfect fruit, and if they cannot find out with what male tree any female tree is in love, they smear the trunk of some tree with the oil which proceeds from her, and then some other tree naturally conceives a fondness for the odour; and these proofs create some belief in the story of their copulation.
