Eleocharis acicularis
Also called Needle spike-rush, Dwarf Hair Grass, Least Spikerush, Wonsan Spikerush, Needle Spikesedge
Needle spikerush is a small, grass-like sedge that forms dense, low mats in shallow water and wet soil. It is best grown submerged or in constantly moist substrate, with bright light and stable water.
Eleocharis acicularis is a species of spikesedge known by the common names needle spikerush and least spikerush. It is widespread across Europe, central and southeastern Asia, North America and northeastern South America as far south as Ecuador. It is also found in Australia, where it is probably an introduced species.
Eleocharis acicularis is an annual or perennial spikesedge with long, grasslike stems to about 15 centimeters (6 inches) 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.
