"Xanthosoma" is a term that refers to a genus of flowering plants in the family Araceae, commonly known as "aroid" or "cocoyam" plants. These herbaceous perennials are native to tropical regions of the Americas and are grown for their edible corn-like corms and leaves. The name "Xanthosoma" is derived from Greek words "xanthos," meaning yellow, and "soma," meaning body, which refers to the yellowish sap present in some species.
