balsa (n.)

1852 as the name of a tropical South American tree noted for its soft, light-weight wood, apparently from Spanish balsa "float," originally the name of rafts used on the Pacific coast of Latin America (attested in English in this sense from 1777, also balza), perhaps from a native word of Peru. Related: Balsa-wood (1913).
