Its range extends north to Trinidad and Tobago, through Venezuela, Guyana, and Suriname, and includes the Brazilian states of Acre, Amazonas, Pará, Rondônia, and Roraima. Its range continues south through the Bolivian departments of Beni, Pando, and Santa Cruz. This palm has multiple human uses. Its fruit is edible, and can be processed to make a type of juice. It is also used to create a symbolic ring called the tucum ring, which is most commonly used in Catholic churches as a symbol of commitment to social justice, peace building, and ecology. A fiber extracted from the plant's leaves is used to make hammocks and ropes that are resistant to salt water.
