This is evidently congeneric with H. intcgrifolium of Mexico, on 

 which Cassini founded his genus Diigaldia; it was also the type of 

 the later genus Oxylepis, of Bentham. The generic characters dis- 

 tinguishing it from Helenitim are given in the Synoptical Flora, 

 where Dr. Gray recognizes it as a subgenus, and less completely in 

 Coulter's Manual as the first section of Helenium. I have seen no 

 specimens of Diigaldia Hoopesii from Montana ; but it is reported 

 from there, according to Dr. Gray. It grows in adjacent Wyoming.

H. montatitim, which represents the eastern H. autumnale in the 

 Rocky Mountain region, differs from that species in the narrowly 

 lanceolate, not oblong-ovate or ovate-lanceolate leaves, which are 

 less sharply dentate, smaller heads in a contracted corymbose panicle, 

 and in the whole plant being densely scabrous-hirsutulous. It grows 

 in river valleys and on prairies, its range extending from Mississippi 

 to Nebraska, Saskatchewan, Montana, Nevada and Texas.
