Corozo Nut, the Spanish name for the seed of the vegetable ivory (Phytelephas macrocarpa), a tree allied to the palms, native to the northern parts of S. America. The albumen becomes as hard as ivory, and is turned into buttons, doorknobs, etc.; but the supply is declining. When young it is edible.
