Large seed capsule and seeds of Brazil nut (Bertholletia excelsa), a giant tree of the Amazon rain forest of Brazil. It belongs to the lecythis family (Lecythidaceae) and is closely related to a group of South American nut trees known as monkey pots. The woody, thick-walled, indehiscent seed capsules are about the size of a large grapefruit and weigh up to five pounds, posing a serious threat to unsuspecting persons walking beneath these trees at certain times of the year.
The Brazil nut tree (Bertholletia excelsa) is an enormous tree of the Amazon rain forest of Brazil. The trees tower 200 feet, and their spreading branches and flowers provide habitat and food for numerous forest creatures. The woody, indehiscent seed capsules are gnawed open by the agouti, a rodent roughly the size of a large guinea pig. The agouti's chisel-like incisors penetrate the Brazil nut capsule. Some seeds are eaten, but others are carried away and buried for future meals. If forgotten, these seeds can remain dormant in the soil for several years and then germinate. Although it consumes some seeds, the agouti is responsible for reseeding the forest with Brazil nuts and ensuring the next generation of trees. Inquisitive primates apparently get their hands stuck inside the woody pods when they reach inside fruits that have been partially gnawed open. This is the derivation of the common name "monkey pot."
For centuries, scientists were puzzled because Brazil nut trees tree do not produce nuts in cultivation or in recently cleared rain forest. This is one of the few economically important plants that are exclusively harvested in their natural rain forest habitat. It turns out that Brazil nut flowers require a certain species of bee for pollination. The bees in turn require a certain species of orchid to survive. Male bees must acquire the fragrance of this particular orchid in order to attract female bees. If the forest is damaged by clearcutting, the orchids disappear, along with the bees and the Brazil nuts.
In Brazil , the nuts are called :Castanha do Pará

The Brazil nut is native to the Amazon region & is called castanha-do-pará (Pará nut) in Brazil. Brazil nut pods are gathered only after they fall to the ground because each weighs about 5 pounds a piece. Gatherers run around gathering them while bearing shields over their heads.

Brazil nut trees (Bertholletia excelsa) produce popular commercial nuts which are a valuable non-timber forest product. Harvested from natural stands in tropical rainforests, their market facilitates forest conservation as well as creating revenue for local peoples.
The Brazil Nut is a South American tree Bertholletia excelsa in the family Lecythidaceae. It is the only species in the genus Bertholletia. It is native to Guiana, Venezuela, Brazil, eastern Colombia, eastern Peru and eastern Bolivia.
Despite their name, the most significant exporter of Brazil nuts is not Brazil but Bolivia, where they are called almendras. In Brazil these nuts are called castanhas-do-Pará, literally "chestnuts from Pará", but Acreans call them castanhas-do-Acre instead.

Other way around. Brazil nuts come from the Brazil tree and we've been eating them for thousands of years.. When the Portuguese arrived in South America, they found them growing there. It's only by chance that the country didn't get called Dandelion.
