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.
1 Few papyri that were made outside Egypt survived. 2  The climate of Egypt and certain parts of Mesopotamia preserved papyri in the ruins of ancient towns and cemeteries. 3  Egyptians used papyrus for 4000 years until other plants and trees were used to make paper for economical reasons.
