Eleocharis obtusa, also known as blunt spikerush, is a widespread plant found in wet areas throughout Canada and the United States. It can be found in riverbanks, moist forest floors, and is also considered a weed in rice paddies. This annual plant can grow up to half a meter tall and has green, cylindrical stems that are weak and spongy. It may also have thin, straw-colored leaves near the base. At the top of each stem, there is a rounded or oblong spikelet containing at least ten flowers, each covered by a brown oval-shaped bract.
