Santalum acuminatum, the desert quandong, is a hemiparasitic plant in the sandalwood family, Santalaceae, (Native to Australia) which is widely dispersed throughout the central deserts and southern areas of Australia.
The species, especially its edible fruit, is also commonly referred to as quandong or native peach. The use of the fruit as an exotic flavouring, one of the best known bush tucker (bush food), has led to the attempted domestication of the species.
Desert quandong is an evergreen tree, its fruit can be stewed to make pie filling for quandong pies or made into a fruit juice drink. The seed (kernel) inside the tough shell can be extracted to be crushed into a paste then be used on sore gums or an oral gum boil to ease the pain. In far-west New South Wales being one of the few drought-tolerant fruit trees around, many Aboriginal communities and local Australians that know about this fruit like to grow it.
Santalum acuminatum grows as a tall shrub, or small tree, high and wide. The rough bark is dark grey and the branches ascending in character. Smaller plants formed by suckers from the roots are sometimes found surrounding larger plants. The smaller branches have a more weeping habit. The slender to ovate leaves are pointed at the tip, and are pale yellowish-green bringing a slightly grey and leathery appearance. These are supported on a short leaf stem, 5 – 10 mm long, the leaves themselves being 45 – 115 mm long. They are tapered in outline, and arranged in opposite pairs on the branchlets.
Flowers can be green or creamy white on the outer parts, reddish or yellowish brown on the inner faces; these appear on stems, are just 2–3 mm across, and are fragrant. Fruit is produced after 4 years and is red or sometimes yellow, measuring between 20 and 25 mm across. A 3-mm layer of flesh covers a brain-like nut with a hard shell that encases the seed. This fruit is referred to as a drupe. It ripens from green to a shiny red in late spring or summer, and is globe-shaped and 20 to 40 mm across. The skin of the fruit is waxy.
