Contemporary with Béroul and Thomas, Marie de France presented a Tristan episode in one of her lais: "Chevrefoil". It concerns another of Tristan's clandestine returns to Cornwall in which the banished hero signals his presence to Iseult by means of an inscription on a branch of a hazelnut tree placed on the road she will travel. The title refers to the symbiosis of the honeysuckle and hazelnut tree which die when separated, as do Tristan and Iseult: ""Ni vous sans moi, ni moi sans vous."" ("Neither you without me, nor me without you.") This episode is reminiscent of one in the courtly branch when Tristan uses wood shavings put in a stream as signals to meet in the garden of Mark's palace.
