This we consider a very distinct Nephrodium, somewhat 
indeed allied to NV. unitum, Schott., but having nothing of the 
harshness and rigidity of that species, and with pinne much 
less deeply lobed, rather serrated than lobed’; and the lower 
pinnz, unusually small and cordate or rotundate, are extended 
down to the base of the stipes; these lesser pinne are always 
barren.
