Santalum is a genus of woody flowering plants, the most well known and commercially valuable of which is the Indian Sandalwood tree, S. album. Members of the genus are trees or shrubs. Most are root parasites which photosynthesize their own food but tap the roots of other species for water and inorganic nutrients. Several species, most notably S. album, produce highly aromatic wood, used for scents and perfumes and for herbal medicine. There are approximately 25 species, ranging across the Indomalaya, Australasia, and Oceania ecozones, from India across Malesia to the Pacific Islands, as far as Hawaii and the Juan Fernandez Islands off the coast of South America.
Indian Sandalwood (S. album) is found in the tropical dry deciduous forests of India, the Lesser Sunda Islands of Indonesia, and Arnhem Land of northern Australia. It is the only species found on the Asian mainland, and may have been introduced to India from the Lesser Sundas centuries ago. Indian Sandalwood has been stripped from most of India's forests, and is now rare in the wild. Five species, including S. album, are native to Australia. S. acuminatum, known as the sweet quandong or native peach, produces a shiny bright red fruit used increasingly in Australia for jams, jellies, chutneys and in pies. Four species, commonly called 'iliahi, are endemic to Hawaii. S. fernandezianum, endemic to the Juan Fernandez Islands off the coast of Chile, was overexploited for its aromatic wood, and may now be extinct.
