Dense Cord-rush is a perennial, rush-like herb with separate male and female plants. Its flowering stems are up to 1.5 m tall, and are narrow and circular in cross section. Flowering spikelets are produced on slender stalks towards the tops of these stems in summer.


Dense Cord-rush has been recorded from the Kanangra-Boyd area to the Southern Tablelands but all populations are small. Populations have been recorded in Blue Mountains National Park, Kanangra-Boyd National Park, Penrose State Forest (in Hanging Rock Swamp), Morton National Park (The Vines), the Clyde Mountain area and Ballalaba (south of Braidwood).

Habitat and ecology

  • Commonly found in swamps or depressions in sandy alluvium, sometimes growing with sphagnum moss.
  • Also occurs in swails within tall forest, and in Black Gum (Eucalyptus aggregata) Woodland.
  • Produces new shoots from underground stems (rhizomes), but little is known about its biology.
