	Ethnobotanical Leaflets
		Hevea brasiliensis was first found in the Amazon basin.
		Hevea brasiliensis is a member of the Euphorbiaceae family (spurge family).
		The plants of the Euphorbiaceae family are mostly monoecious herbs, shrubs, and trees, sometimes succulent and cactus-like, and comprise one of the largest families of plants with about 300 genera and 7,500 species that are further characterized by the frequent occurrence of milky sap.

	Condomerie - Discovering the Rubber tree
		Hevea brasiliensis was later discovered further south in the Brazilian state of Pará.
		Opinion had gradually crystallised into the view that Hevea brasiliensis, source of Pará rubber, was the best because this species not only produced the precious sap freely, but the wounds caused by tapping healed without difficulty.
		To the Director's delight, it turned out to be 70,000 seeds of Hevea brasiliensis, gathered on the banks of the River Tapajós, a side-river of the Amazon between Manaus and Belem in the state of Pará, Brazil.

		In the cultivation of Hevea, the natural contours of the land are followed,and the trees are protected from wind.
		Hevea grows only within a well-defined area of the tropics and subtropics where frost is never encountered.
		Cultivation of Hevea in Brazil, its native habitat, was virtually destroyed by blight early in the 20th century.

	EH.Net Encyclopedia: The International Natural Rubber Market, 1870-1930
		The best source of latex, the milky fluid from which natural rubber products were made, was hevea brasiliensis, which grew predominantly in the Brazilian Amazon (but also in the Amazonian regions of Bolivia and Peru).
		The Hevea brasiliensis, the most important type of rubber tree, was an Amazonian species.
		Brazil tried to prevent Hevea brasiliensis seeds from being exported, as the Brazilian government knew that by being the main producers of rubber, profits from rubber trading were insured.

	Appendix B: Description of Wood Species Emission of chemical compounds from products made of exotic wood
		Brasiliensis has been grown to extract natural rubber (latex).
		The species has to a large extent been planted in other tropical regions including West Africa and Southeast Asia, as the latex production is unprofitable in the Amazon due to a plant disease, which makes it impossible to grow rubber tree — except for scattered growths.
		Brasiliensis have been felled and converted into other crops, and thus a lot of rubber tree has been placed on the market.

	RUBBER (Site not responding. Last check: 2007-10-14)
		Commercially, natural rubber is obtained almost exclusively from Hevea brasiliensis, a tree indigenous to South America, where it grows wild to a height of 34 meters(120 feet).
		In the cultivation of Hevea, the natural contours of the land are followed, and the trees are protected from wind.
		Dried sheets are packed into 110-kilogram (250-pound) bales for shipping.About 10 percent of all natural rubber is shipped as latex, concentrated by centrifugation to a rubber content of approximately 60 percent and used for making dipped goods such as surgical gloves, prophylactics, and toys.

	FROM THE AMAZON TO THE INDIANAPOLIS 500
		Of course, the hevea rubber plant is now grown on plantations in other wet tropical regions, but until the 1900s Brazil had a monopoly on this plant product.
		Au contraire, in the New World Hevea brasiliensis has been seriously hurt by a fungal disease call leaf blight (Microcyclus), so that the plant has essentially disappeared from its native home, and crude rubber must now come from Old World plantations.
		During the 19th century, nearly all crude rubber came out of the jungles of Brazil from native plants of Hevea brasiliensis, although natural rubbers from guayule (Parthenium argentatum) and Castilla plus a few other plants were also used.

		Polyisoprene synthesis in laticiferous cells of Hevea brasiliensis, stimulated by ethylene, requires an exogenous supply of sugar.
		In Hevea, rubber synthesis is confined to the cytosol of the highly differentiated laticifer cells.
		The present study of laticifer protoplasts from Hevea brasiliensis, cells which are specialized for stress response, has revealed through a switch-clamp method, an outward rectifying current displaying rapid inactivation.

		In Hevea, the branch growth phase effect persisted into the multiplication phase when shoots developed in vitro were used as the source of secondary nodal explants.
		In Hevea, the position of secondary nodal explants obtained from the primary shoot was seen to vary in effect depending on growth regulator applications during primary culture.
		These results are analyzed in terms of variations in the balance between endogenous growth promoters/inhibitors in the buds, depending on morphogenic stages and the bud position on the branch.
