À very slight comparison of this plant with the /Zoodsia Perinniana (Tas. 68.) of this work, will 
suffice to show how closely the two Ferns are allied. In regard to genus, the involucre has pre- 
cisely the same structure in both: but in their fronds we find a difference, particularly in the pri- 
mary pinne, which in JZ'. Perinniana are almost deltoid, while here they are linear-oblong; and in 
the pinnules, which in the former are pinnatifid, in the latter only toothed at the margin. -
