 An unnatural aggregate of plants of very dissimilar

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

 a whiti Mf y. Il.n\ wa.'iy powder, which has given the

 in the We<r, the "i Jolden-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.
