Native Apricot - inedible!

This is Pittosporum angustifolium, otherwise known as the native apricot, Butterbush, Cattle Bush, Gumbi Gumbi, etc. It is a hardy desert species first described in 1832.  While the fruit is inedible its leaves are the most useful in indigenous medicine. Traditionally aboriginal people pounded the leaves to help with eczema, skin irritations and arthritis. A warm compress would also help bring on milk in nursing mothers. Some sort of cure-all from what I read. It also produces a chewable gum. These trees can live for up to 100 years. This seed is no more than 1cm across.
