Has. New Holland. Introduced in 1828 by Mr. 4. Cunningham. 
Oss. The very great differenee in habit of this and another 
species (from New Zealand) from the other species of Dictyopteris 
of Presl., has induced me to separate them; the three known 
species which I retain under Dictyopteris differ from Dictymia in 
having large compound bipinnate or tripinnatifid fronds, with 
the sori numerous and irregularly torent and although I have 
not had the opportunity of examining their rhizoma, yet, judging 
from analogy and the structure of the stipes, I have every reason 
to believe that the vernation of the fronds is not articulated with 
the rhizoma as in Dictymia.
