<P> The fruit takes 14 months to mature after pollination of the flowers . The fruit itself is a large capsule 10--15 cm (3.9--5.9 in) in diameter, resembling a coconut endocarp in size and weighing up to 2 kg (4.4 lb). It has a hard, woody shell 8--12 mm (0.31--0.47 in) thick, which contains eight to 24 triangular seeds 4--5 cm (1.6--2.0 in) long (the "Brazil nuts") packed like the segments of an orange . </P> <P> The capsule contains a small hole at one end, which enables large rodents like the agouti to gnaw it open . They then eat some of the seeds inside while burying others for later use; some of these are able to germinate into new Brazil nut trees . Most of the seeds are "planted" by the agoutis in shady places, and the young saplings may have to wait years, in a state of dormancy, for a tree to fall and sunlight to reach it, when it starts growing again . Capuchin monkeys have been reported to open Brazil nuts using a stone as an anvil . </P> <P> Despite their name, the most significant exporter of Brazil nuts is not Brazil but Bolivia, where they are called castañas o nuez de Brasil . In Brazil, these nuts are called castanhas - do - pará (literally "chestnuts from Pará"), but Acreans call them castanhas - do - acre instead . Indigenous names include juvia in the Orinoco area . In Cuba, the nut is alternatively called coquito de Santiago, literally St. James coconut . </P> <P> Though it is commonly called the Brazil nut, in botanical terms it is the seed from the fruit of this tree . To a botanist, a nut is a hard - shelled indehiscent fruit . (An example of a botanical nut would be an acorn or a hazelnut .) </P>
