'''Dipterocarpaceae''' is a [[family (biology)|family]] of 17 genera and approximately 580-680 species of mainly [[tropical]] lowland [[rainforest]] [[tree]]s with two-winged fruits. The largest genera are ''Shorea'' (360 species), ''Hopea'' (105 species), ''Dipterocarpus'' (70 species), and ''Vatica'' (60 species). Many are large [[forest]] emergent species, typically reaching heights of 40-70 m tall, with the tallest known living specimen over 85 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]] and [[Malaysia]], with the greatest diversity and abundance in western [[Malaysia]]. Some species are now [[endangered species|endangered]] as a result of overcutting and extensive [[illegal logging]]. They provide valuable woods, aromatic [[essential oil]]s, [[balsam]], [[resins]] and as a source for [[plywood]].

Because most specimens are illegally harvested, Greenpeace suggests that consumers avoid using meranti.[http://archive.greenpeace.org/foresthouse/foresthouse.swf]

The dipterocarp family is generally divided into three subfamilies:

* Monotoideae: 3 genera, 30 species. ''[[Marquesia]]'' is native to [[Africa]]. ''[[Monotes]]'' has 26 species, distributed across Africa and Madagascar. ''[[Pseudomonotes]]'' is native to the Colombian Amazon.

* Pakaraimoideae: contains a single species, ''[[Pakaraimaea roraimae]]'', found in the [[Guiana|Guaianan highlands]] of South America.

* Dipterocarpoideae: the largest of the subfamilies, it contains 13 genera and 470-650 species. Distribution includes the [[Seychelles]], [[Sri Lanka]], [[India]], [[Southeast Asia]] to [[New Guinea]], but mostly in west Malaysia, where they form the dominant species in the lowland forests. The Dipterocarpoideae can be divided into two groups (Ashton, 1982; and Maury-Lechon and Curtet, 1998):
**Valvate-Dipterocarpi 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 (Dayanandan ''et. al.'', 1999) suggest that the genus ''Hopea'' forms a clade with ''Shorea'' sections ''Anthoshorea'' and ''Doona'', and should be merged into ''Shorea''.

A recent genetic study (Ducousso ''et. al.'' 2004) found that the Asian dipterocarps share a common ancestor with the [[Sarcolaenaceae]], a tree family endemic to Madagascar. 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.
