Mentioned in the Anguttara Commentary (i.74), among the Jātakas revealed by the Buddha at Sankassa in answer to the questions asked by Sāriputta.
No story of this name is found in the Jātaka Commentary, but the verse quoted in the Anguttara Commentary is found in the Jhānasodhana Jātaka (J.i.473f), for which evidently this was another name.
An Anangana Vatthu is mentioned in the Samantapāsadikā (i.158), but the reference is not clear, and probably refers to Anangana Sutta (infra).
