Identification:
Wheki ponga is one of the most easily recognised species of tree fern in New Zealand. It is very distinctive with its thick, sturdy trunk covered with densely matted, fibrous roots, and the prominent skirt of dead fronds that gird its trunk just below the crown. The trunk is 30-60 cm in diameter in its lower part. The individual fronds are from 1.2-2.4 m long by 40-60 cm wide. They are quite harsh to the touch. The upper surfaces are green to dark green.

Informations générales:
Maori used to use the trunks of Wheki ponga for the construction of food store houses, because the thick, fibrous trunks made them almost impenetrable to rats.
