Ivory Nut. The seed of a low growing palm native to South America. The seeds grow in clusters, from four to nine together. Each seed is about as large as a hen's egg. When dried, the grain is very hard, resembling the finest ivory in texture and color; it is hence called vegetable ivory, and is often wrought into ornamental work and buttons. [See Buttons]
