Abstract Macrothelypteris torresiana
(Thelypteridaceae) is recorded for the first time from mainland New Zealand,
from the Surville Cliffs, near North Cape, in the North Island. Prior to this
discovery,
M. torresiana was only known within the New Zealand botanical
region from Raoul (Rangitahua) Island, Kermadec Islands. The presence of this
tropical fern at North Cape provides an additional example of a vagrant element
within the flora of mainland New Zealand.
Keywords Thelypteridaceae; Macrothelypteris
