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.[1] 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.[1][2] 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.[3] The Juncus Continuus, like it’s many cousins, is a flowering plant, sporting clusters of small brown flowers on the ends of leaf-like stems.[4]
