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