Eleocharis macrostachya is a species of spikesedge known by the common name pale spikerush.

It is widely distributed in North America and occurs in parts of South America.^[1]^[2] It is a plant of varied moist habitats, including freshwater lakes and brackish marshes and ponds, ditches, vernal pools, and wet meadows.

Description[]

Eleocharis macrostachya is a rhizomatous perennial generally reaching heights between one half and one meter. It has bright green erect stems and straw-colored basal leaves. The top of each stem is occupied by a narrow, lance-shaped or cylindrical inflorescence. The spikelet is one or two centimeters long and has at least ten flowers, each covered with a purplish-brown bract. The fruit is a yellow or yellow-brown achene with a whitish cone-shaped tubercle on one end, measuring one or two millimeters long.^[3]

Use in phytoremediation efforts[]

E. macrostachya has been studied as part of wetland restoration, as well as the removal of arsenic in groundwater via rhizofiltration as part of phytoremediation.^[4]^[5] Wetlands have the capacity to remove many conventional contaminants from wastewater, even in highly saline water.^[6] Olmos-Marquez (2012) identified E. macrostachya as having the greatest arsenic retention in an experimental wetland, suggesting that it acts as a rhizofiltrator.^[7]^[8]
