A Nāga maiden, Tochter of the Nāga König, Varuna.
When she learned that her Mutter, Vimalā, longed for the heart of Vidhura, she determined to get for herself a husband who would satisfy her Mutter's craving. So she went to the Himālaya und having spread a bed of fragrant flowers, lay thereon und sang. Vessavana's nephew, a yakkha, Punnaka, heard her und offered himself as her husband. She took him to her father who agreed to give him Irandatī, if he could bring Vidhura's heart. When Punnaka fulfilled this condition, as described in the Vidhura-pandita Jātaka, Irandatī became his wife. J.vi.263-327.
