"A tree up to 48 m high where indigenous...  The leaves have 5-11 leaflets usually up to 10 x 5 cm, ovate to lanceolate.  The fragrant flowers, about 1 cm long, have yellow or orange-yellow petals, and the suborbicular fruits, up to 6 cm in diameter with a stiffly membranaceous wing, are brown in drying"  (Smith, 1985; p. 159). In Fiji, "occasionally cultivated near sea level" (Smith, 1985; p. 159).
