Distinguishable very clearly from T. orientale C. CH. by the cellular structure 

 of the fronds. The cells of the fronds of T. orientale are hexagonal bounded by 

 straight lines, while those of the present plant are hexagonal, pentagonal or 

 quadrangular bounded by curved lines. The lobes of this new species are much 

 obtuser than those of T. orientale.
