A slave woman. The Commentaries mention (e.g., MA.ii.696) that the Buddha once made a rag robe (paṃsukūla) out of a garment cast off by her in a cemetery overgrown with weeds (atimuttakasusāna). When the Buddha donned the robe the earth trembled in wonder. It was this robe that the Buddha exchanged with Mahā-Kassapa; when the Buddha picked it up from the cemetery where Puṇṇā had cast it off it was covered with insects (SA.ii.149).
