Pinus merkusii

A different reason for appropriating a material object comes from the kauri (Agathis alba) and merkus (Pinus merkusii) pine forests of Malaysia. Local people collect soft resin from these trees and sell it as a cash crop. Under the name Malay damar, this exudate is exported as a valued ingredient for high quality varnishes.
