Cyperus difformis is also known by people in Indonesia as puzzle grass, which is a type of aquatic plant that is usually easily found in various freshwater habitats throughout the world. This plant is characterized by slender leaves and tiny flowers with white mixed with green leaves, and when the Cyperus difformis flowers are old they will change to maroon and brown. Where we live Cyperus difformis often becomes a serious problem in the rice fields because the Cyperus difformis plant really interferes with the growth of the cultivated rice plants, therefore the Cyperus difformis plant considered a weed that destroys crops.
