Tapping a rubber tree. Natural rubber is produced by many New World plants,the most important of which is the rubber tree,Hevea brasiliensis. Raw rubber is obtained from a milky latex exuded by the tree in response to injury; exactly why the latex is produced is not known. Tapping involves scoring a spiral cut through the bark. The latex flows slowly out and drains into a collecting cup. A single tree can yield up to 30g from a cut before the flow stops. Native to Brazil,the rubber tree was introduced in the early 20th century to Malaysia,which is now the world's largest producer of rubber. Photographed in Malaysia | |
