The Dipterocarpaceae are a family of 16 genera and about 695 known species of mainly tropical lowland rainforest trees. The family name, from the type genus Dipterocarpus, is derived from Greek and refers to the two-winged fruit. The largest genera are Shorea, Hopea, Dipterocarpus, and Vatica. Many are large forest-emergent species, typically reaching heights of 40–70 m, some even over 80 m, with the tallest known living specimen 93.0 m tall. The species of this family are of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina, Indonesia, Malaysia and Philippines. The greatest diversity of Dipterocarpaceae occurs in Borneo. Some species are now endangered as a result of overcutting, extensive illegal logging, and habitat conversion. They provide valuable woods, aromatic essential oils, balsam, and resins, and are a source for plywood.
Dipterocarpus is a genus of flowering plants and the type genus of family Dipterocarpaceae.
Zeuxine, commonly known as verdant jewel orchids, is a genus of about eighty species of orchids in the tribe Cranichideae. They are native to parts of tropical Africa, Asia, Southeast Asia, New Guinea, Australia and some Pacific Islands. They have relatively narrow, dark green leaves and small, dull-coloured resupinate flowers with the dorsal sepal and petals overlapping to form a hood over the column. The labellum has a pouched base and its tip has two lobes.
Cotylelobium melanoxylon is a tropical rainforest tree found in Maritime Southeast Asia. The name melanoxylon is derived from Greek and describes the dark heartwood. It is a very good quality timber, as it has very hard and heavy as well as durable wood. C. melanoxylon is a tall emergent tree, up to 60 m, found in mixed dipterocarp forest on yellow sandy soils. It also occurs as a smaller canopy tree in kerangas forest on podsols. The tree occurs in at least three protected areas. Local names of the tree include Resak tembaga in Malay and Khiam (เคี่ยม) in Thai. The tree is the provincial symbol tree of Surat Thani Province, Thailand.
Shorea teysmanniana is a timber tree of the family Dipterocarpaceae. It occurs in Sumatra, Peninsular Malaysia and Borneo.
Hopea is a genus of plants in the family Dipterocarpaceae. The genus was named after John Hope, 1725–1786, the first Regius Keeper of the Royal Botanic Garden, Edinburgh. It contains some 113 species, distributed from Sri Lanka and southern India to southern China, and southward throughout Malesia to New Guinea. They are mainly main and subcanopy trees of lowland rainforest, but some species can become also emergent trees, such as Hopea nutans.
Parashorea macrophylla is a species of plant in the family Dipterocarpaceae. The name macrophylla is derived from Greek and refers to the species extremely large leaves. It is endemic to Borneo, being found in Brunei, Sarawak and West Kalimantan. The timber is sold under the trade name of white lauan or white seraya. It occurs in protected areas in Sarawak but elsewhere it is threatened by habitat loss.
Shorea siamensis is a species of tree in the family Dipterocarpaceae. It is native to most of mainland Southeast Asia.
Stemonoporus is a genus of plants in the family Dipterocarpaceae.
Cotylelobium is a genus of plants in the family Dipterocarpaceae. The name Cotylelobium is derived from Greek and describes the receptacle. It contains five species distributed in Sri Lanka, Peninsular Thailand, Sumatra, Peninsular Malaysia and Borneo. All five species are listed on the IUCN redlist, as either vulnerable, endangered or critically endangered.
Anisoptera is a genus of plants in the family Dipterocarpaceae. The name Anisoptera is derived from Greek and describes the unequal fruit calyx lobes. It contains ten species distributed from Chittagong (Bangladesh) to New Guinea. Eight out of the ten species are currently listed on the IUCN redlist. Of these, four species are listed as critically endangered and the other four as endangered. The main threat is habitat loss. The timber is a light hardwood.
Parashorea smythiesii is a species of plant in the family Dipterocarpaceae. It is endemic to Borneo. It is a large emergent tree, up to 55 m tall, found in mixed and upper dipterocarp forests on fertile clay soils. It is found in some protected areas.
Parashorea parvifolia is a species of plant in the family Dipterocarpaceae. The name parvifolia is derived from Latin and refers to species small leaves. It is endemic to Borneo. It is a large emergent tree, up to 60 m tall, found in mixed dipterocarp forests on fertile clay soils. It is present in protected areas, including Lambir Hills National Park.
Cotylelobium burckii is a species of plant in the family Dipterocarpaceae. The species is named after W. Burck, (1848–1910), a botanist that worked on the Dipterocarpaceae and the Sapotaceae. C. burckii is a canopy tree, up to 40 m, found in kerangas forests on deep white sand podsols. The species is endemic to Borneo. It is found in at least two protected areas.
Cotylelobium lanceolatum is a species of plant in the family Dipterocarpaceae. The name is derived from Latin and refers to the shape of the leaf blade. C. lanceolatum is a canopy tree, up to 45 m, found in kerangas forests on raised beach terraces and sandstone plateaux and on organic soils over limestone. The species is found in Peninsular Thailand, eastern coastal areas of Peninsular Malaysia, the Anambas Islands and Borneo. It is found in at least two protected areas.
Shorea exelliptica is a species of plant in the family Dipterocarpaceae. This species has previously been confused with Shorea elliptica and the species name is derived to highlight this point.
Dipterocarpus lowii is a tree in the family Dipterocarpaceae.
Hopea jucunda is a species of plant in the family Dipterocarpaceae. It is endemic to the island of Sri Lanka.
Farmeria is a genus of flowering plants in the family Podostemaceae, native to Sri Lanka and India. They attach to rocks using holdfasts, and their flowers are protected by boat-shaped spathella until they emerge.
Christisonia is a genus of flowering plants belonging to the family Orobanchaceae.
