Dipterocarpaceae occurs as family of 17 genera & close to 580-680 coinage of chiefly tropical lowland rainforest trees with both-winged fruits. A big genera come Shorea (360 metal money), Hopea (105 mintage), Dipterocarpus (Lxx metal money), & Vatica (Lx coinage). Several come big forest emergent species, often reaching heights of 40-70 m tall. A coinage of this personal come of major importance in the timber trade. Their distribution is pantropical, from northern South America to Africa, the Seychelles, India, Indochina and Malesia, with a greatest diversity & abundance within american Malesia. A bit of metal money come at present endangered as a result of overcutting and extensive illegal logging. It provide worthful outdoors, redolent essential oils, balsam, and rosin.
A dipterocarp personal is usually divided into tercet subfamilies:
Monotoideae: Triplet genera, Thirty mintage. Marquesia is native to Africa. Monotes has 26 metal money, distributed through Africa & Madagascar. Pseudomonotes is native to the Colombian Amazon.
Pakaraimoideae: contains one coinage, Pakaraimaea roraimae, found in the Guaianan highlands of South America.
Dipterocarpoideae: a largest of the subfamilies, it contains Baker's dozen genera & 470-650 mintage. Distribution includes a Seychelles, Sri Lanka, India, Southeast Asia to New Guinea, but mostly around west Malesia, in which it form a dominant mintage in the lowland forests. A Dipterocarpoideae may be divided into ii groups (Ashton, 1982; & Maury-Lechon & Curtet, 1998):
Valvate-Dipterocarpi class action (Anisoptera, Cotylelobium, Dipterocarpus, Stemonoporus, Upuna, Vateria, Vateriopsis, Vatica). A genera of this class action st& valvate sepals inside fruit, solitary vessels, scattered rosin canals, and basic chromosome benumb x = Xi.
Imbricate-Shoreae class action (Balanocarpus, Hopea, Parashorea, Shorea). A genera of this class action use at times imbricated sepals inside fruit, sorted vessels, rosinside canals in digressive elastic, & basic chromosome blunt x = Septenary. The recent molecular survey (Dayanandan et. al., 1999) indicate that a genus Hopea forms the clade by using Shorea sections Anthoshorea & Doona, & should exist as merged into Shorea.
The recent transmitted learn (Ducousso et. al. 2004) observed that a Asian dipterocarps part a most common ascendent by owning the Sarcolaenaceae, a tree personal autochthonous to Madagascar. This suggests that root of the Dipterocarps originated in the southern supercontinent of Gondwana, & that a most common ascendant of a Asian dipterocarps & a Sarcolaenaceae was observed in the India-Madagascar-Seychelles l& mass hundreds to thousands of years ago, & were carried northbound by India, which late strike Asia and allowed the dipterocarps to spread through Southeast Asia and Malesia.
