is perhaps not meri sree from A. ebeneum, which it replaces i in Fike dryer regions of 
the Mets and Mexico, It is a smaller and more rigid plant, with the pinne more entire, and more

Asplenium septentrionale, Hoffmann. 
Plant low, growing in dense tufts; rootstocks matted together, hidden 
by the blackened remains of old stalks; fronds crowded, 2—4 inches high, 
the slender naked stalk bearing an irregularly forking frond, consisting of 
from two to five narrowly linear rather rigid acute segments or branches, 
which are entire or more frequently cleft at the end into a few long narrow 
teeth; sori much elongated, placed near the margin, usually facing each 
other in pairs, commonly only two or three to each segment—*“ Deutsch.
