This species has roots that are partially parasitic on a range of other plants and is widespread across much of dryland southern Australia [1,2,3]. It extends from coastal south west Western Australia, across southern Northern Territory, most of South Australia, to New South Wales and south western Queensland. Santalum acuminatum is usually a small tree to 5 m tall. It is found in a wide range of habitats, often as isolated trees.
Flowering and seeds
Flowering in this species starts in late autumn but has been recorded in October to March along the coast in south west Western Australia ; fruits ripen during late winter and spring and soon drop. There are about 20* viable seeds per 10 grams; seeds start to germinate in about 10 days if grown at 20°C with no pretreatment required .
Cultivation and uses
Santalum acuminatum is a slow growing, fire-sensitive species adapted to semi-arid and arid conditions. Its root system is parasitic and dependent on the roots of a host plant to establish . The outer fleshy layer of the fruit is used to make jams and conserves, sauces and various confectionary products, while the hard kernel is also edible and has a high protein, vitamin C and oil content . Plantations to produce commercial quantities of fruit from this species have recently been established . The foliage of this species is apparently 'relished' and heavily grazed by stock  and it is considered a useful amentity plant .
