Dicksonia duhia of many authors. Davallia duhia of gardens and some 

 New Zealand herbaria. Barren fronds of a fern referred to this have often 

 been obtained in Canterbury and Otago, but I have not been able to obtain 

 any native specimens in fruit, and perhaps the plant may turn out to be 

 Microlepia forsteri. Many other ferns are said to grow in New Zealand, but 

 their occurrence requires authentication.
