Blechnum discolor. Piupiu. Petipeti. Crown fern.
Lomaria discolor (in Best).
Kiore, native rat, wrapped in leaves of petipeti for cooking in hangi ( Best 1902)
Common in drier and more open forest. The bent-over fronds have been used as track-markers - their pale undersides are visible even at night. (Crowe 1994)
In the south, it is said that the kakapo will bite the fern off at the base and hold the frond over its head to shield itself from observation (Beattie 1920).
