Pacific ferns: taxonomy and relationships

Te Papa researchers: Leon Perrie, Patrick Brownsey and Lara Shepherd

Over half of Aotearoa’s ferns and lycophytes are also indigenous elsewhere in the south-west Pacific region. Improving the understanding of the floras adjacent to New Zealand therefore provides better context for our work on its own ferns and lycophytes. Our investigations involve the delimitation, naming, distributions, and relationships of species.

With its shared Zealandian heritage, New Caledonia is a special focus, but we’ve also published on Australian, Solomon Islands, Fijian, and Tongan ferns.
