Hab. In forests, on the Corcovado, near Rio Janeiro, and Organ 

 Mountains, Brazil. 



This bears a considerable resemblance to the M. sorbifolia, Swartz, 

 and M. fraxinea, Smith ; but is readily distinguished by its more 

 delicate texture, the deeper serrate margin of its pinnules, and by the 

 interrupted or vacant spaces in the lines of sporangia.

Hab. Tahiti, Society Islands. 



Distinct from M. cicutcefolia in the shorter and opposite pinnae, the 

 larger and more coriaceous, serrulate pinnules, with the line of spo- 

 rangiferous receptacles continuous, and seated about half a line from 

 the margin.

Hab. Ovolau, Feejee Islands. 



From the preceding species this may be recognised by its attenuated 

 pinnse, its narrower and more numerous, coriaceous, deeply serrated 

 pinnules, of a pale green colour on the under surface; the line of 

 sporangia more distant from the margin, and the sporangia them- 

 selves shorter.
