A kind of reedmace (bulrush), Typha orientalis (family Typhaceae), formerly used by Maori as a building material, for thatch, etc. Frequently attributive. Also in elliptical use (now historical): a hut built of, or thatched with, this plant.
Formerly regarded as representing an endemic Australasian species, Typha muelleri, but now considered conspecific with T. orientalis of China and Japan.
Early 19th century. From Maori raupō.
