I. On the Propagation of Plants — continued. 



B. Propagation by Buds. 



The bud is the most important part of the plant; for it is only 

 by it, and the various forms which it assumes, that the increase, 

 or propagation, of plants is effected. It appears first as a normal 

 perfect bud. Out of this, through various changes, comes the 

 fruit. Secondly, it appears in the f'onn of a btid, which does 

 not, however, become developed in the usual way. The meta- 

 morphoses of the latter have a more decided and marked indi- 

 viduality; and consist of the hidb, tuber-bulb (Knollenzwiebel), 

 bulb-bud (Zwiebelknospe), the need, and of a bud which by 

 cultivation and casualty is capable of becoming also a perfect 

 individual bud. I do not by any means intend to assert that 

 these germs can assume at will any one of these various forms, 

 for the changes which the bud undergoes in various respects 

 have their origin in its earliest existence. It is in order to 

 direct the attention to the analogy frequently existing between 

 them, and to examine more closely into the principles before 

 laid down, that the first part of this chapter is dedicated, while 

 the second part will consist of the practical propagation of plants 

 by cuttings, buds, leaves, &Cc, in connexion with these principles. 



1. Buds and their Metamorphoses. 



The normal perfect bud, which Frederic Wolff termed a 

 perfect plant, displays in its functions a certain individuality; so 

 that, under certain conditions, it may be considered the germ of 

 an entirely individual plant. Monch represented it as the part 

 from which the plant, without previous fructifying, is increased ; 

 and C. G. Nees von Esenbeck calls it the undeveloped nucleus
