Another Tamil word for creepers is Valli, the honey collecting daughter of the chief of the Veddas mountain tribe. The chief and his wife prayed to the Mountain God for a girl-child and their prayers were answered when the chief found a new-born girl child during a hunting expedition. As she was found among creeper plants, they named the child Valli and she grew up as princess of the tribe in Kurinji and became the consort of lord Murugan.
