   Indies; cf. Sp. papayo papaw, papaya the fruit of the papaw.]
   [Written also {pawpaw}.]
   1. (Bot.) A tree ({Carica Papaya}) of tropical America,
      belonging to the order {Passiflore[ae]}. It has a soft,
      spongy stem, eighteen or twenty feet high, crowned with a
      tuft of large, long-stalked, palmately lobed leaves. The
      milky juice of the plant is said to have the property of
