Eleocharis acicularis is a species of spikesedge known by the common names needle spikerush and dwarf hairgrass. It has a circumboreal distribution and it can also be found throughout the rest of the Americas. It is also found in Australia, where it is probably an introduced species. This is an annual or perennial spikesedge with long, grasslike stems to about 15 centimeters in height, shorter in bog conditions, from a creeping rhizome. In shallow water it will form short spikes of tiny flowers amongst flat overlapping bracts. The tiny flowers are less than five millimeters in diameter and are borne at the tip of each stem in single, sharply pointed, lanceoloid spikelets up to about six millimeters long. This is a plant of marshes, vernal pools, and bogs, and it is also used as an aquarium plant. It thrives with plenty of light and a high concentration of carbon dioxide.
