Eleocharis torticulmis is a rare species of flowering plant in the sedge family known by the common names twisted spikerush and twist-stem spikerush. It is endemic to Plumas County, California, where it is known from two locations within a kilometer of each other in the Butterfly Valley Botanical Area.[1][2] It grows in open wet habitat such as fens and meadows. It was separated from Eleocharis suksdorfiana and described to science as a new species in 2001.[3]
This perennial spikerush grows from a tiny rhizome and a small, hard caudex. It produces a tuft of erect stems 20 to 40 centimeters tall. Each stem is spirally twisted and contracted near the tip, becoming somewhat flattened. The spikelet is under a centimeter long and contains up to 10 tiny flowers.
