The affinity of this species is with D. polylepis (Fr. et Sav. ) of China and 
Japan. It is characterized by its thick erect rhizome, its double villosity con- 
sisting of large blackish _ scales and grayish-yellow pubescence, its somewhat 
fleshy texture, and its very large brown persistent coriaceous indusia. It has 
the general appearance of a small member of the filix mas group, but its nerves 
are simple. An alpine form.
