Botanical Name:       Cyperus ustulatus

Maori Name:            Toe toe, Upoko-tangata

Common Name:        Coastal cutty grass


Coastal cutty grass is widespread on Tiritiri Matangi.  It’s clumps provide shelter for lizards and ground nesting birds.  It’s harsh leaves have a sharp cutting edge, derived from a high silica content.  The flower stems are triangular in shape and the specific name ustulatus (scorched) describes the dark brown sooty colour of the flower heads.


Cyperus is a large, world wide genus and one member, Cyperus papyrus, which has a similar general form to our cutty grass, was used in ancient Egypt to produce the writing material papyrus.


Cyperus is Greek for sedge or marsh plant.  An alternative common name, giant umbrella sedge, is also used.


Maori used the leaves as an outer thatching material for their dwellings.
