 extend along the veins in various lines. A large num- 

 ber of the species are coated on the under surface with 

 a white or yellow waxy powder, which has given the 

 names of Gold Perns or Silver Ferns. Two species occur 

 in the West, the "Golden-back" of California, and a 

 species less common from Arizona and other parts of 

 the Southwest. Over 80 species of wide distribution 

 have been included in the genus, which by many is di- 

 vided into a series of natural genera. The name Gym- 

 nogramma itself is probably not tenable.
