This beautiful and seemingly widespread species lias been confused with 

 /). soUda and h. divaricata. It differs from the former in being larger, thinner, 

 liner cut, with beaked indusiuni and teeth flanking most sori; from the latter 

 in the narrow, marginal sori. it superficially resembles I>. elegant, but has long 

 sori and no false veins.

Itciuafkable for the naked rhizome, small lowest pinnae, and often marginal 

 sori. While the aspect suggests Dennstaedtia, the structure of the sorus, and 

 the receptaeulum in particular, make me believe that it is most fitly placed in 

 Microlepia.

This fern is lunch larger and more complex than />. smith it ( Hk.) Moore usually 

 is. has less difference in color between the two surfaces, and differs conspicuously 

 in its broad, instead of almost linear, primary pinnules. This or a similar
