Mangabeira rubber is collected to a limited extent, and piassava fibre is an article of export.
The most important palm of the country perhaps is the Raphia vinifera, which produces the piassava fibre of commerce.
The exports also include hides, mangabeira rubber, piassava fibre, diamonds, cabinet woods and rum.
The fibre of the piassava (Leopoldinia piassava, or Attalea funifera) is widely used for cordage, brushes and brooms. There are many other palms whose fruit, fibre and wood enter largely into the domestic economy of the natives, but the list given shows how important a service these trees rendered to the aboriginal inhabitants of tropical America, and likewise how useful they still are to the people of tropical Brazil.
