Obs. This plant is doubtless an JEchinocactus, and 

 to prevent confusion (as above-mentioned) ought to 

 occupy the name of nobilis, althougli by some modern 

 authors it has been changed. Such worse than useless 

 alterations ever breed confusion. They blur the 

 beauty of our flowery science, and clog its progress 

 to perfection, in a needless way. No name how- 

 ever great, no authority however bold, nor any argu- 

 ment however ingenious, ought at this enlightened 

 period to be encouraged, by adopting such wilful, 

 useless, and unnecessary change.
