VARIETIES. 



In plants of the same species, there are fre-

 chiefly in their magnitude, time of flowering, scent, 

 taste, duration, pubescence, form of their leaves, 

 colour of their flowers, and the production of 

 monstrous flowers. 



Plants may differ from each other in any of 

 these respects, and yet be of the same species ; 

 and then they are termed Varieties, 



None of the characters above enumerated are

 respects, may not produce other plants possessing

 And again, with respect to flowers, a plant which
