Dipterocarpus gracilis (Tagalog: panao / Indonesia: kaboa aka sancang) is a critically endangered species of tree in the family Dipterocarpaceae, native to South Asia and Southeast Asia. [1]
The species is found in Kalimantan, Bangladesh, India (the Andaman and Nicobar Islands, Arunachal Pradesh, Assam and Tripura), Indonesia (Java, Kalimantan, Sumatra), Peninsular Malaysia, Myanmar, Thailand, the Philippines, Vietnam and China (Yunnan Province).
This large tree is found in lowland seasonal semi-evergreen and evergreen dipterocarp forests.
It is often used as a commercial grade plywood, it is one of the most important sources of keruing timber.
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 coriaceus is a species of tree in the family Dipterocarpaceae endemic to Kalimantan, Sumatra and peninsular Malaysia. This very large tree occurs in mixed dipterocarp forests on hillsides and undulating land. This species was reported in the New Straits Times to be extinct in Peninsular Malaysia in July 2013 as its last natural habitat in Bikam Forest Reserve in Perak was de-gazetted and cleared for oil palm cultivation.
Dipterocarpus cornutus is a species of tree in the family Dipterocarpaceae native to peninsular Malaysia, Singapore, Sumatra and Kalimantan. Reaching heights of up to 50 meters tall, it is known for having large leaves. Its flowers are around 4 cm in diameter and of a pale yellow colouration. It drops seeds with green holes in the middle.
Dipterocarpus elongatus is a species of tree in the family Dipterocarpaceae found in Indonesia, Malaysia and Singapore. This large tree occurs in secondary and primary forest, as well as in freshwater swamp forest.
Dipterocarpus fusiformis is a species of tree in the family Dipterocarpaceae. The tree is endemic to Borneo, where it is found in Central and East Kalimantan provinces of Indonesia and Sabah state of Malaysia.
Dipterocarpus glabrigemmatus is a species of tree in the family Dipterocarpaceae. The tree is endemic to Borneo.
Dipterocarpus globosus is a species of tree in the family Dipterocarpaceae endemic to Borneo, where it occurs in Brunei, Sarawak (Malaysia) and Kalimantan (Indonesia).
Dipterocarpus hasseltii is a species of tree in the family Dipterocarpaceae. This large tree occurs in lowland dipterocarp forest and is cut for keruing timber. It is found in Indonesia, Peninsular Malaysia, Sabah, the Philippines, Thailand and Vietnam.
Dipterocarpus humeratus is a species of tree in the family Dipterocarpaceae. The species name humeratus is derived from Latin and refers to the articulated petiole. D. humeratus is an emergent tree, up to 50 m tall, found in mixed dipterocarp forests on well-drained clay soils. The species is found scattered or semi-gregarious on undulating land and clay ridges below 700 m elevation. It is found in Sumatra and Borneo and occurs in at least three protected areas.
Dipterocarpus kerrii is a species of tree in the family Dipterocarpaceae, native to the Andaman Islands, Sumatra, Borneo, Peninsular Malaysia, Laos, Myanmar, the Philippines, Singapore, Thailand and Vietnam.
Dipterocarpus semivestitus is a species of tree in the family Dipterocarpaceae, occurring in Kalimantan and peninsular Malaysia. This tree is almost always found in lowland forest on swampy land. It is very close to extinction.
Dipterocarpus validus is a species of tree in the family Dipterocarpaceae, endemic to Kalimantan, Sabah and the Philippines. The species is common in both primary and secondary forest, often occurring along rivers and in freshwater swamps. It yields wood-oil and is cut for keruing timber.
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.
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.
Dipterocarpus alatus, also known colloquially as the resin tree, is a tropical forest tree, of dense evergreen or mixed dense forests, in tropical Asia. It is considered vulnerable.
Spongiforma is a genus of sponge-like fungi in the family Boletaceae. Newly described in 2009, the genus contains two species: S. thailandica and S. squarepantsii. The type species S. thailandica is known only from Khao Yai National Park in central Thailand, where it grows in soil in old-growth forests dominated by dipterocarp trees. The rubbery fruit bodies, which has a strong odour of coal-tar similar to Tricholoma sulphureum, consists of numerous internal cavities lined with spore-producing tissue. S. squarepantsii, described as new to science in 2011, is found in Malaysia. It produces sponge-like, rubbery orange fruit bodies with a fruity or musky odour. These fruit bodies will—like a sponge—resume their original shape if water is squeezed out. The origin of the specific name derives from its perceived resemblance to the cartoon character SpongeBob SquarePants. Apart from differences in distribution, S. squarepantsii differs from S. thailandica in its colour, odour, and spore structure.
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 turbinatus is a species of tree in the family Dipterocarpaceae native to north-eastern India and mainland Southeast Asia, and cultivated in surrounding regions. It is an important source of the wood known as keruing, and is often used in the plywood industry.
Dipterocarpus lowii is a tree in the family Dipterocarpaceae.
Dipterocarpus stellatus is a tree in the family Dipterocarpaceae. The specific epithet stellatus means "star-like", referring to its trichomes.
