Dipterocarpus alatus, the resin tree, [3] is a tropical forest tree, of dense evergreen or mixed dense forests, in tropical Asia. It is considered vulnerable. [1]
Dipterocarpus alatus is a large tree, growing 30–60 m (98–197 ft) tall. It is insect pollinated, and sets fruit between March and April. Its seeds are wind dispersed. [1]
Dipterocarpus alatus ranges from West Bengal and Bangladesh through Myanmar, Thailand, Laos, Cambodia, Vietnam and the Philippines. [1] It is also native to Sri Lanka and the Andaman Islands. [1]
It grows in evergreen and semi-evergreen lowland dipterocarp forests in valleys and foothills. It is often found on ancient alluvial, granite, and basalt rock substrates. It requires humid and well-drained soil. It tolerates flooding but not fire or wind. [1]
It often occurs gregariously along river banks and is a key planting species for regenerating deforested land around the Dong Nai river and Cat Tien National Park.
In Cambodia, the wood is much valued in construction and cabinetwork, when not exploited for its oily resin. Generally, resin is collected for the following uses: wood lacquering, draught-proofing of boats and traditional medicine. When mixed with beeswax, it is used in bandages for ulcerated wounds. The bark of young trees is also used in traditional medicine, taken against rheumatism and diseases of the liver, and to stimulate appetite in cattle. [4]
In Myanmar, one of the largest of the species is in Kengtung, see photos.
Dipterocarpus retusus, commonly known as hollong, 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. 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.
Dipterocarpus grandiflorus is a species of flowering plant in the Dipterocarpaceae family. It is an endangered medium hardwood tree of Southeast Asia. It is a large tree which can grow up to 50 metres tall.
Sindora siamensis is a species of tree in the subfamily Detarioideae of the family Fabaceae. It has an accepted infraspecific, the variety S. siamensis var. maritima (Pierre) K.Larsen & S.S.Larsen. See taxon box to the right below, and below for details on the variety maritima. The nominate species is found in many countries in tropical Asia. Like several other species in the genus Sindora, its wood is considered valuable; the least concern conservation status may reflect efforts to replant this species, but mortality rates are high. As well as the wood, the plant provides raw material for chemical products, food and drink, and domestic utensils.
Aglaia edulis is a tree species of plant in the family Meliaceae. It occurs in Tropical Asia from India to Yunnan and South-Central China. The wood and timber are used for various purposes.
Anisoptera costata is an endangered species of plant in the family Dipterocarpaceae. The specific epithet costata means "ribbed", referring to the prominent venation of the leaf blade. A huge emergent tree up to 65 m high, it is found in evergreen and semi-evergreen lowland tropical seasonal forests of Indo-Burma and in mixed dipterocarp forests of Malesia.
Campylospermum serratum is a plant in the family Ochnaceae. The specific epithet serratum is from the Latin meaning "with teeth", referring to the leaf margin. It is found in Tropical Asia, from Sulawesi, Indonesia to Hainan, Zhōngguó/China and over to southwestern India. Gomphia serrata was a previous common name for the species. The plant is used for it wood and its sap is used in folk medicine and in the past for teeth-blackening.
Shorea obtusa, the Siamese sal, is a species of hardwood tree in the family Dipterocarpaceae, native to Southeast Asia.
Vatica harmandiana, also known by the synonym Vatica cinerea, is a species of plant in the family Dipterocarpaceae. It is a smallish tree native to Southeast Asia. It is the most common plant species in certain types of mature woodland habitat within its range and is furthermore common in disturbed secondary forests covering much of its range, nonetheless it was considered, along with most Dipterocarpaceae, to be endangered by the IUCN between 1998 and 2017. It is usually not commercially harvested except for local use.
Dipterocarpus tuberculatus is a species of tree in the family Dipterocarpaceae found in Bangladesh, Myanmar, Thailand, Cambodia, Laos and Vietnam. The tree is found in clear forests of plains, at altitudes up to 800–1,000 m (2,600–3,300 ft). It grows to a height of 5–25 m (16–82 ft).
Dipterocarpus costatus is a species of tree in the family Dipterocarpaceae found in the Indochinese and Malay Peninsulas, including Cambodia. The tree is found in "mixed dense deciduous or half-deciduous forest of the plain and in wet dense altitude forest, up to 1200 m, on well drained rich grounds." It grows to a height of 25-40m. In Cambodia the resin is used particularly for the caulking of boats, and the preparation of torches, the wood used for work not exposed to the elements.
Dipterocarpus dyeri (Khmer: rôyiëng, chhë tiël pruhs, chhë tiël th'nô:r, local name Kompong Thom: chhieutiel chgor, name used for commercial timber and the group of trees harvested for such: keruing, Vietnamese: Dầu Song Nàng, is a species of tree in the family Dipterocarpaceae found in Myanmar, Thailand, Peninsular Malaysia, Cambodia, Vietnam, and northwestern Borneo. The tree is found in rain forest and lowland semi-evergreen dipterocarp forests, an alternative habitat description is mixed dense forests of the plains, mainly among rivers and valleys. The tree is a climax or late successional species, which in some secondary forests forms relatively young pure colonies. The conservation status is based on rates of habitat loss, the major threat to the taxa, though in Vietnam it is cited as having a less threatened conservation status of Vulnerable.
Dipterocarpus intricatus is a species of tree in the family Dipterocarpaceae found in Thailand, Cambodia, Laos and Vietnam.
Dipterocarpus obtusifolius is a common species of tree in the family Dipterocarpaceae found throughout Southeast Asia, including Andaman Islands, Myanmar, Thailand, Cambodia, Laos and Vietnam.

It is associated with a number of species of fungus, insects and animals, including emus. Amongst the Mangarrayi and Yangman people of north Australia, the sweet ripe fruit of the tree are much appreciated and linked to the build-up season and to the koel.
