Styrax paralleloneurus

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