Remarks, This is one of the commonest and most variable of the Coal 

 Measure plants, and numerous specific names have been applied to the 

 different forms of it, but from Filicites lonchiticus, as figured by Schlotheim, 

 to Alethopteris gracillima, Boulay, a chain of gradations connects the two 

 extremes.
