Santalum

Santalum is a genus of woody flowering plants in the Santalaceae family, the best known and most 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. It has about 25 known species which are native to Island Southeast Asia (Indonesia, Timor-Leste, and the Philippines), Melanesia (Papua New Guinea, Vanuatu, Fiji, and New Caledonia), Australia, Polynesia, the Bonin Islands of Japan, and the Juan Fernández Islands of Chile.

Indian sandalwood (S. album) is native to the tropical dry deciduous forests the Lesser Sunda Islands of Indonesia, the Philippines, and Arnhem Land of northern Australia. It is the only species of the genus found on the Asian mainland, having 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 pies. Four species, (including Santalum paniculatum, commonly called iliahi), are endemic to Hawaii. S. fernandezianum, endemic to the Juan Fernández Islands off the coast of Chile, was also overexploited for its aromatic wood, and may now be extinct.
