2f. 6 — 10. — This species is found sparingly in every locality, and 
in each is almost always associated with A. septentrionale, with which 
it agrees in the involucre, and of which it may only be a variety ; 
from states of the next with a less compound frond and longer 
pinnules than usual, it is best known by the involucre.

bipinnate especially below, pinnules cuneate-obovate (sometimes 
cuneato-lanceolate) lobed or toothed at the apex, sori linear
