[Wikipedia] Native range: Casuarina equisetifolia, common names Coastal She-oak or Horsetail She-oak[1] (sometimes referred to as the Australian pine tree or whistling pine tree outside Australia), is a she-oak species of the genus Casuarina. The native range extends throughout Southeast Asia, Northern Australia and the Pacific Islands; including Thailand, Myanmar, Vietnam, Malaysia, Singapore, Brunei, Indonesia, East Timor, and the Philippines (where it is known as agoho pine),[2] east to Papua New Guinea, French Polynesia, New Caledonia, and Vanuatu, and south to Australia (north of Northern Territory, north and east Queensland, and north-eastern New South Wales).[3] Populations are also found in Madagascar, but it is doubtful if this is within the native range of the species (link added by Mary Ann Machi)
