Hab. United States, Michaux : rich woods W. NeAv England to Michigan; 

 Kentucky, along the mountains, Asa Gray. Canada, Cleghorn. — A species very 

 easily recognized by its dimorphous fronds (the fertile pinnae smaller than the 

 sterile ones), the copious and regularly placed sori, and the tumid involucres, 

 quite athyrioid, of a firm texture.

 — Our figure and character are taken from fine specimens gathered by Moritz, 

 and are the same as Mettenius's plant, 1. c. I have already alluded to its close 

 affinity vrith the A. Feci. Kunze speaks of its proximity to A. fair, Desv. 

 and A. auriculatum, Sw., which are here united under tlie latter name. 

 Moore refers it to A. falx, and 1 must confess that my sjiecimens from 

 linden seem to form a connecting link: nevertlieless, the absence of the 

 peculiar auricle may justify its being kept distinct. The distinguishing 

 marks are given in our two figures. Tab. CLXXl. and CLXXII. — I think 

 Mettenius has done riglit in uniting my A. fragrans (so called, l)ecause Dr.
