Styrax paralleloneurus (syn. Styrax sumatranus) is a species of Styrax native to Sumatra and Peninsular Malaysia.[1] It is the main source of benzoin Sumatra or Sumatran benzoin,.[2] Its balsamicresin is superior than that of Styrax benzoin, another source of benzoin Sumatra, as the latter dries slowly and remains sticky, hence more inpurities.[3][4]
