Caustis pentandra, known as the thick twist rush is a widely distributed grass like plant found in many parts of Australia. It may grow to 2 metres tall, often seen in dry open forest, or moist heathland. [1] Stems are a shiny pale green. The specific epithet pentandra is derived from the ancient Greek language, referring to five stamens.
