Etymology: Epiphyllum is a genus name coined in modern botanical Latin, built from Greek roots: "epi", meaning "upon", and "phyllon", meaning "leaf". The name describes how these plants behave: their flattened, leaf-like stems grow out of the surface of other plants, so the flower-bearing stems seem to sit on top of a leaf. Early botanists who named the genus were describing that growth habit rather than naming a plant that grows from leaves. Because the name was created for a scientific classification, it does not come from ancient Greek or Latin usage. It belongs to the vocabulary of systematic plant naming, where classical roots were combined to label newly described species. The English word "epiphyllum" is borrowed directly from this international scientific Latin, so it keeps the same spelling in many languages. "Epiphyllums" is simply the plural form, used when referring to more than one plant of this kind.
