Inca wheat or quihuicha Amaranthus caudatus, a species of the large group of amaranth plants and one of the most notable of those which have been used to provide grain food. It was food for the Inca in ancient times, lapsed into oblivion after the Spanish Conquest, and is now experiencing a revival.
Inca wheat and its relations are not true cereals, a term which applies only to the cultivated grasses of the family Graminaceae; but, like other plants whose fruits and seeds can be ground into flour with uses like those of the cereals, they are accorded the status of ‘para-cereal’.
