Also known as  grasstrees, the form of the plant resembles a tree, with very long and bunched, grass-like, leaves that emerge from a central base. It is found throughout Southwest Australia and is of high economic importance to the Noongar people, who named it balga, using the gum it contains and the spike for fish spears. Its essential oil is ethereal in nature, slightly floral and mineral, very light and delicate. It is nevertheless very scarce due to the lack of visibility in the global market and because its extraction requires specific measures to protect from the dust the process creates.
