Santalum murrayanum

Santalum murrayanum, commonly known as the bitter quandong, is an Australian plant in the sandalwood family, Santalaceae. The Noongar name for the plant is coolyar.

It bears a bitter fruit, from which a common name derives, in contrast to congener Santalum acuminatum - sweet quandong. The plant is also known as Ming. It occurs in a hemi-parasitic relationship with the roots of several other plants, in a non-destructive way, as with all the species of the genus Santalum.

The shrub or small tree typically grows to a height of 1 to 5 m. It blooms between October and January producing white to yellow-green flowers. It is found on sandplains and dunes and has a scattered distribution through the Wheatbelt, Great Southern and Goldfields-Esperance regions of Western Australia where it grows in sandy or gravelly lateritic soils.
