Austroderia is a genus of five species of tall grasses native to New Zealand, commonly known as toetoe (from Māori).

[6] Two closely related South American species are Cortaderia jubata and C. selloana (Pampas Grass), which have been introduced to New Zealand and are often mistaken for toetoe.

Among the differences between Pampas, Toetoe has a drooping flower head, a cream coloured plume, and the leaves do not break when tugged firmly.

[3] The Māori used the toetoe leaves to make baskets, kites, mats, wall linings and roof thatching.

Cutty grass is also used in New Zealand to refer to Gahnia setifola (mapere), Cyperus ustulatus (upoko tangata) and Carex geminata.
