Quandong (Santalum acuminatum)
Description
Santalum acuminatum, the desert quandong, is a hemiparasitic plant in the Sandalwood family Santalaceae, widely dispersed throughout the central deserts and southern areas of Australia. The species, especially its fruit, is also referred to as quandong or native peach. The use of the fruit as an exotic flavouring, one of the best known bushfoods, has led to the attempted domestication of the species. Santalum acuminatum grows as a tall shrub, or small tree, 4 to 6 m (13 to 20 ft) high and 2–4 m (6.6–13.1 ft) 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, are pale or yellow green, and leathery. 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 white on the outer parts, reddish or brown on the inner faces; these appear on stems, are just 2–3 mm across, and are fragrant. Fruit is produced after four 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. Roots are adapted to a hemi-parasitic mechanism, utilising a haustorium, on roots able to reach out 10 metres to other root systems.
