The durian is the fruit of several tree species belonging to the genus Durio. There are 30 recognised Durio species, at least nine of which produce edible fruit, with over 300 named varieties in Thailand and 100 in Malaysia, as of 1987. Durio zibethinus is the only species available in the international market: other species are sold in their local regions. It is native to Borneo and Sumatra.
