COLLECTING, SELECTING, AND PROPAGATING AUSTRALIAN PLANT INTRODUCTIONS
W. Rodger Elliot
The Australian flora is often referred to as being unique, but this is not an accurate description, as most of our Australian plants belong to families that are widely distributed throughout other parts of the world.
The Australian flora is closely linked with the world flora, and the endemic species have evolved since the continent was isolated. The flora can be roughly divided into three main elements:
- Asian. Many species from the Kimberleys, Western Australia, Northern Territory, northern and eastern Queenland, coastal New South Wales and far eastern Victoria have links with the Pacific and Asian region, especially those found in rainforest areas.
- Antarctic. The relationship with New Zealand, sub-antarctic island, and South America is obvious and south-eastern Australia, especially Tazmania.
- Australian. The unique development of endemic plants has occurred since isolation, especially in Western Australia, sue to the dry barriers of central Australia and Nullar-bor Plain.
