three to six Inches long, succulent and easily broken off, and 

 covered with tubercles in a spiral arrangement. The spicules 

 are white and are formed in tufts, while the spines, seven

 Arizona and Northern Mexico.

 established. They are not Injured by temperatures of 

 twenty or twenty-five degrees below freezing, and grow in-
