the sori various in position, generally on the back of united veinlets ; 
fronds simple, pinnatifid or pinnate, articulate with the caudex. 
In the Synopsis Filicum Phymatodes is the name adopted for this 
genus (or subgenus only in that work) ; this name, however, is of 
much later date than Pleopeltis, having been instituted by Presl. 
in 1836, Pleopeltis by Humboldt and Bonpland in 1810. Some 
authors split the genus up into many genera.
