Ferns and fern allies of Macquarie Island

and other subantarctic islands

Macquarie Island is a treeless windswept island at approximately 55° south latitude, midway between New Zealand and Antarctica. Its pteridophyte flora is very depauperate and numbers only 5, sharing its species with Tasmania and southern Australia, New Zealand, southern South America and the other subantarctic islands that lie above 50° parallel.

These islands represent some of the harshest and most extreme cold environments in which ferns and their allies can be found.
