Blechnum novae-zelandiae (Kiokio)
Scientific name: Blechnum novae-zelandiae
Common name: Kio kio, Kiokio Blechnum Capense,
Kiokio (Blechnum novae-zelandiae) it can be found growing abundantly on clay banks along roadsides and rivers. The long cascading fronds (up to 2m long and 50cm wide) are a bright pink colour when new, and turn light green and then darker green as they mature.Blechnum novae-zelandiae on the bank of the upper Te Henui walkway
When young, many fronds (both sterile and fertile) are rich in unmasked red pigments (anthocyanins). As they mature, green chlorophyll predominates.
Sterile and fertile fronds - Leaflets (pinnae) on sterile fronds are 5-10 mm broad while those of the blackish fertile frond are 2-5 mm across. Both the sterile fronds and the fertile fronds are elliptic in shape and seldom exceed 250 cm in length.

Underside of a fertile leaflet - The leaflet is only wide enough to bear sporangia in one continuous row on each side of the midrib. Prior to spore release the covering (indusium, attached on the side nearest the frond margin) pulls back from the midrib to expose the sporangia. Large scales are attached to the midrib.
