Goeppertia allouia (syn. Calathea allouia), known as lerén or lairén in Spanish, and also known in English as Guinea arrowroot, and sweet corn root, is a plant in the arrowroot family, native to northern South America and the Caribbean. The name "allouia" is derived from the Carib name for the plant. Lerén is a minor food crop in the American tropics, but was one of the earliest plants domesticated by pre-historic Amerindians in South America.
Distribution
Goeppertia allouia is native to Cuba, Hispaniola, Puerto Rico, the Lesser Antilles, Trinidad and Tobago, Venezuela, Colombia, Ecuador, Peru and Brazil. It is reportedly naturalized in Jamaica.
Lerén has been introduced as a minor root crop in tropical regions around the world.
Description
Lerén (Goeppertia allouia)
Lerén is a perennial plant, approximately 1 metre (39 in) in height. It produces egg-shaped tuberous roots 2 centimetres (0.79 in) to 8 centimetres (3.1 in) long at the end of fibrous roots. The leaves are large, up to 60 centimetres (24 in) long and 20 centimetres (7.9 in) wide. Indigenous people of the Americas have used the durable leaves to make traditional medicines and as baby clothing. Lerén usually reproduces itself through rhizomes which produce shoots and new plants.
