Juncus continuus

Juncus continuus is a perennial plant found in many parts of Australia; namely the regions of Queensland and New South Wales. Juncus continuus has also been introduced in Great Britain and New Zealand, and invasive in Texas. Often growing on sandy, moist soils, near fresh water. The specific epithet refers to the continuous pith within the stems. Basal leaves are reduced to sheaths, colored yellow/brown and split at the base. While the Juncus continuus is a fairly new discovery, its plant family has been documented for many years. First beginning in a journal published by Johann Friedrich Gmelin titled, "Systema Naturae" between 1788 and 1793. The Juncus Continuus, like its many cousins, is a flowering plant, sporting clusters of small brown flowers on the ends of leaf-like stems.
