LECT. IX.] HYBERNACULA. 449 



is objectionable only in expressing an opinion, as 

 to the early state of the bud, that may be dis- 

 puted*. Some hybernacula remain attached to 

 the parent ; others detach themselves after a cer- 

 tain period, but both kinds are to be regarded as 

 the lateral progeny of the plant ; for even that 

 which remains attached possesses, in a certain de- 

 gree, a separate or distinct vitality, by which it is 

 enabled to exist when forcibly detached from the 

 parent. Thus a bud taken from a tree, and pro- 

 perly planted in the ground, covered with a glass 

 to prevent too great an exhalation of its natural 

 moisture, will grow and become a tree resembling, 

 in every respect, that from which it was taken. 

 But still the plant, whether raised from a bud 

 thus forcibly detached, or from one which na- 

 turally detaches itself, is an extension only of the 

 parent, displaying all its individual peculiarities 

 the effects of soil or culture, and inheriting all its 

 diseases; whereas a plant raised from a seed is 

 a new individual, displaying the generic and 

 specific characters only of the parent. From 

 the same cause, also, plants which are natives of 

 a warm climate, when taken to a colder, and pro-

 mirable simplicity which characterizes all Linnaeus 's defini- 

 tions is here conspicuous ; but the definition is objectionable in 

 being equally applicable to the seed as to the hybernaculum.
