This plant has in habit and the shape of the pinnae and seg- 

 ments, some resemblance to PellcEa Seeinanni, Hooker, and in 

 giving Mr. Brandegce the names of the ferns he collected in his

 gathered in January and a part of a frond gathered a few months 

 later, when the pinnoc were more fully expanded.
