Mentioned in the Aṅguttaranikāya Commentary (i.74), among the Jātaka stories revealed by the Buddha at Saṅkassa 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 Aṅguttara Commentary is found in the Jhānasodhana Jātaka (J.i.473 f), for which evidently this was another name.
An Anaṅgana Vatthu is mentioned in the Samantapāsadikā (i.158), but the reference is not clear, and probably refers to Anaṅgana Sutta (infra).
