Eleocharis acicularis is a species of
spikesedge known by the common names needle spikerush
[2] and least spikerush . It is widespread across
Europe , central and southeastern
Asia ,
North America and northeastern
South America as far south as
Ecuador .
[3] It is also found in
Australia , where it is probably an
introduced species .
[4]
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.
[4]
Eleocharis acicularis is sold commercially as an
aquascape plant suitable for inclusion in artificial aquatic environments. It thrives with plenty of light and a high concentration of
carbon dioxide .
[5]
[6]
The
specific epithet , acicularis , is derived from
Latin and means "needle-shaped".
[7]

[3]
Eleocharis acicularis var. acicularis – most of species range
