The following, with white-pubescent but scabrous leaves and more

 variety and the next; Utah: St. George, 1877, Palmer 238 (G); 



36 According to Nelson's description the lower leaves are opposite, but I 

 have been unable to find evidence of this in the material at hand, and opposite 

 leaves are unknown elsewhere in the genus.
