Webster Dictionary(0.00 / 0 votes)Rate this definition: Epiphyllum(noun) a genus of cactaceous plants having flattened, jointed stems, and petals united in a tube. The flowers are very showy, and several species are in cultivation.
Epiphytes are commonly found in the temperate zone (like in temperate rainforests). A few examples of epiphytes are moss, and lichen. Epiphytes use photosynthesis to get energy, and take moisture from the air (rain, fog), roots grow mainly so that the epiphyte can attach to the other plant, usually a tree.
