On Genus Amorphophallus Blume ex Decne (Araceae) in Cuba

Abstract

Context: The presence in several Cuban cities of Amorphophallus Blume ex Decne (Araceae), which has been poorly and unelaborately published in the scientific literature, encouraged researchers to conduct a systematic, phytogeographic, and ethnobotanical study of this plant. Aim: To unveil the nomenclature, taxonomy, phenotypical characterization, differences from akin taxons, distribution, and usefulness of specimens of Amorphophallus Blume ex Decne, currently cultivated in Cuba outside scientific collections. Methods: Specimens kept in gardens of the city of Camagüey were studied using methods such as collection work, descriptor and key comparisons, and scientific description and illustration. Results: The presence in Cuba of genus Amorphophallus Blume ex Decne was confirmed, proving that it is related to other three species: A. paeoniifolius (Dennst.) Nicolson, A. konjac K. Koch, and A. titanum (Becc.) Becc. ex Arcang. The determination of the nomenclature was determined more accurately; the genus and other two species were described. Besides, the analytical key was adjusted to contrast the different Araceae genuses present in the country; another key was presented to contrast the two species described. Aspects related to their usefulness (corroborated or potential) were discussed from different perspectives: food and medicinal properties, and as a nutritional enhacer of soil.
