 perennial variety which is again separated into vari- 

 eties named C. candidissima, 0. cleinentei, and C. gym- 

 nocarpa. These possess no important distinguishing 

 differences which are of interest here.

 rusty and greenish-white flowers — it is the anthers 

 which are rust-color ; the rest of the rather unin-

 of small, dull-yellowish flowers which slightly remind 

 one of the white golden-rod. In Italy, among the
