Dioclea megacarpa) is a species of flowering plant in the family Fabaceae, native to Central America, Colombia, Peru, Bolivia, northern Brazil, Trinidad and Tobago, and the Windward Islands.^[1] A climber, it is typically found in wet tropical rainforests.^[1][2] Its seeds contain large amounts of the non-proteinogenic amino acid L-canavanine,^[2] which replaces the essential arginine producing abnormal proteins and enzymes and resulting in severe malnutrition to insect pests and other herbivores.^[3]
