Papyrus is made from a plant that grows on the banks of the Nile River in Egypt. The aquatic plant, Cyperus papyrus, grows up to 15 feet (4.5 meters) high. Its green, triangular stem has long, sharp leaves and flower clusters 10 to 20 inches (25 to 50 cms) long. These flowers bloom at the tip.
Paper History. The word paper comes from the ancient Egyptian writing material called papyrus, which was woven from papyrus plants. Papyrus was produced as early as 3000 BCE in Egypt, and in ancient Greece and Rome. Further north, parchment or vellum, made of processed sheepskin or calfskin, replaced papyrus, as the papyrus plant requires subtropical conditions to grow.
