Lomandra insularis

Lomandra, commonly known as mat rushes, is a genus of perennial, herbaceous monocots in the family Asparagaceae, subfamily Lomandroideae. The genus was first described in 1805 by Jacques Labillardière. There are 51 species, all of which are native to Australia; two of them also extend into New Guinea and New Caledonia. They are generally tufted dioecious perennials with long narrow blade-like leaves that arise from a central stemless base and have thick woody rhizomes and fibrous roots.
