Eleocharis pachycarpa is a species of spikesedge known by the common name black sand spikerush. This plant is native to southern South America (Chile , Argentina , Paraguay, Uruguay) but it grows in other parts of the world as an introduced species, such as Australia and the US states of California and Nevada.[1][2][3][4]
Eleocharis pachycarpa is a resident of moist areas, such as riverbanks, vernal pools, salt marshes, and wet meadows. This is a rhizomatous perennial generally not exceeding 40 centimeters in height. It forms clumps of very thin stringlike stems of smooth bright green which are four-sided or cylindrical. The stems are somewhat erect but they bend easily to become stolons; if the tip touches the substrate it may root there and produce a new plant. The spikelet is a flat oval shape up to a centimeter long and holds ten or more flowers, each covered in a dark purple-brown or black bract. The fruit is a tiny light-colored achene about a millimeter long.
