Seeds dispersed over long distances: Anisoptera tree

The two spear-shaped wings of Anisoptera tree seeds enable long-distance dispersal because they are asymmetrical.

  "Anisoptera, one of the tallest of the trees in the same Asiatic forests, also has two wings, but they are spear-shaped and curve upwards and outwards. As its name suggests, they are also unequal in length. This asymmetry causes them to spin when they are released, and the seed resembles a tiny whirling helicopter, which may travel even further than a double-winged glider." (Attenborough 1995:19)

The Dipterocarpaceae are a family of 17 genera and approximately 500 species of mainly tropical lowland rainforest trees. The family name, from the type genus Dipterocarpus, is derived from Greek (di = two, pteron = wing and karpos = fruit) and refers to the two-winged fruit. The largest genera are Shorea (196 species), Hopea (104 species), Dipterocarpus (70 species), and Vatica (65 species).[2] Many are large forest emergent species, typically reaching heights of 40–70 m tall, some even over 80 m (in the genera Dryobalanops,[2] Hopea[3] and Shorea),[3] with the tallest known living specimen (Shorea faguetiana) 88.3 m tall.[3] 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 and Malaysia. The greatest diversity of Dipterocarpaceae occurs in Borneo.[4] Some species are now endangered as a result of overcutting, extensive illegal logging and habitat conversion. They provide valuable woods, aromatic essential oils, balsam, resins and are a source for plywood.


The dipterocarp family is generally divided into three subfamilies:

Phylogeny of the Dipterocarpaceae[4]





















  • Dipterocarpoideae: the largest of the subfamilies, it contains 13 genera and about 475 species. Distribution includes the Seychelles, Sri Lanka, India, Southeast Asia to New Guinea, and a large distribution in Borneo, where they form the dominant species in the lowland forests. North Borneo (Brunei, Sabah and Sarawak) is the richest area in the world for dipterocarp species.[2] The Dipterocarpoideae can be divided morphologically into two groups,[4][5] and the tribe names Shoreae and Dipterocarpeae are sometimes used, but genetic evidence so far does not support this division:[6][7]
    • Valvate - Dipterocarpeae group (Anisoptera, Cotylelobium, Dipterocarpus, Stemonoporus, Upuna, Vateria, Vateriopsis, Vatica). The genera of this group have valvate sepals in fruit, solitary vessels, scattered resin canals, and basic chromosome number x = 11.
    • Imbricate - Shoreae group (Balanocarpus, Hopea, Parashorea, Shorea). The genera of this group have imbricate sepals in fruit, grouped vessels, resin canals in tangential bands, and basic chromosome number x = 7. A recent molecular study suggest that the genus Hopea forms a clade with Shorea sections Anthoshorea and Doona, and should be merged into Shorea.[8]

A recent genetic study found that the Asian dipterocarps share a common ancestor with the Sarcolaenaceae, a tree family endemic to Madagascar.[9] This suggests that ancestor of the Dipterocarps originated in the southern supercontinent of Gondwana, and that the common ancestor of the Asian dipterocarps and the Sarcolaenaceae was found in the India-Madagascar-Seychelles land mass millions of years ago, and were carried northward by India, which later collided with Asia and allowed the dipterocarps to spread across Southeast Asia and Malaysia. The first dipterocarp pollen has been found in Myanmar (which at that time was part of the Indian plate) and it dates from the upper Oligocene.[10] The sample appears to slowly increase in terms of diversity and abundance across the region into the mid-Miocene[10] Chemical traces of dipterocarp resins have been found dating back to the Eocene of India.

Fossilized arthropods[edit]

52-million-year-old amber found in the Gujarat province, India, containing a large amount of fossilized arthropods, was identified as sap from the Dipterocarpaceae family.[11]


Dipterocarpaceae species can be either evergreen or deciduous.[12] Species occurring in Thailand grows from sea level to c. 1300 m elevation. Environments in which the species of the family occur in Thailand include: Lowland dipterocarp forest 0–350 m; Riparian fringe; Limestone hills; and Coastal hills.
