Cyperus papyrus is a reed native to North Africa, belonging to the family Cyperaceae[?] of the order Cyperales. Ancient Egyptians used the plant for many purposes, most famously for making papyrus paper. Cyperus papyrus is now used mainly for decoration, as it is nearly extinct in its native habitat.
