Dipterocarpus retusus, commonly known as hollong,[3] is a large tree and perhaps the best known species in the genus Dipterocarpus. It is native to China, Vietnam, Philippines, Laos, Cambodia, Malaysia, Indonesia, Myanmar, and India.[1][4] The tree, some 20–30 metres (70–100 ft) tall, is found in Cambodia in dense forests of the plains, common on hillsides and along rivers and in forests between 800 m (2,600 ft) and 1,500 m (5,000 ft) altitude.[4]
Hollong (Dipterocarpus macrocarpus) is the State Tree of Assam, India. Hollong is a medium hardwood, timber tree. It grows naturally in forests of upper Assam and Arunachal Pradesh. Hollong is a sacred tree for Moran community of Assam. Today Hollong is used in plywood industries.[citation needed]
Uses
It is famed for its timber and resin. In Cambodia, the resin is collected by people in the mountainous regions, in order to make torches and candles, while the wood is used in construction to make columns and boards.[4]
