Ficus rubiginosa
Ficus rubiginosa, the rusty fig, Port Jackson fig, or little-leaf fig (damun in the Sydney language) is a species of flowering plant in the family Moraceae that is native to eastern Australia. It is a banyan of the genus Ficus which contains around 750 species worldwide in warm climates, including the common fig (Ficus carica). Ficus rubiginosa can grow to 30 m (100 ft) high and nearly as wide with a buttressed trunk, and glossy green leaves.
