Piupiu

 
 

A generic name for a small group of vaguely palm-like ferns: Blechnum procerum, Blechnum discolor, Blechnum novaezelandiae (Blechnaceae), & Pneumanopteris pennigera (Thelypteridaceae).

NOTE - THIS PROTO-PAGE IS STILL IN THE EARLY STAGES OF CONSTRUCTION!

In many parts of the Pacific, a reflex of the original Proto Malayo Polynesian root word *biRu denotes one or more species of fan palm. The Mäori reflex, a reduplicated form of the Proto-Polynesian root *piu (which elsewhere in Polynesia generally denotes the fan palm Pritchardia pacifica), is a term applied to four species of fern, three of which (Blechnum procerum, B. discolor, and Pneumanopteris pennigera) develop short trunks (up to a metre high in the case of P. pennigera), and the fourth (Blechnum novaezelandiae) has a profusion of broad fronds which can reach up to 3 metres in length in ideal situations.

While they share the designation of a single name inherited from earlier stages of the Polynesian language, each of these ferns is also known by other, locally developed names. The Blechnum species are endemic to New Zealand; the Pneumanopteris is also found natively in Australia. Blechnum novaezelandiae has the largest number of alternative names (perhaps reflecting its variability and tendency to hybridize with some other Blechnum species): horokio, kiokio, korokio, koropiu (this incorporates the inherited root word), koropio, mokimoki, tupari and rautao; B. discolor is also known as petipeti, täniwhaniwha and turukio; B, procerum as kiokio (note the shared element, kio, in these sets of names); and Pneumanopteris pennigera as päkau and päkauroharoha.

Photographs and further information:

There is basic information about all these ferns (along with more photographs) on the NZ Plant Conservation Networks web site: Blechnum discolor, B. novaezelandiae (including the Department of Conservation photograph reproduced above), B. procerum and Pneumanopteris pennigera. The photograph of P. pennigera is by Larry Jensen, on the University of Auckland Biological Sciences site, which also has some information about the medicinal uses of this fern. The photo of Blechnum procerum is from the Driftwood Eco-tours (Marlborough) web site.
