In Sanskrit and South Indian languages traditions, Pallav can also be written as Pallava, with an additional vowel "a" in the end.
In the Sundara Kanda chapter of Ramayana, when Lord Hanuman visits Lanka to find Sita ji, he hides in a tree of Ashok Vatika; the soft leaves (Pallavas) of that tree give shelter and comfort to Lord Hanuman.
In the available works of Indian history, the other known usage of this name comes from the Pallava Dynasty of South India.
