hybernacula, or winter habitations, and in their 

 expanded state. 



The pyramidal bodies which I have just no- 

 ticed are well known by the name of buds; and 

 the appellation is so universally applied in this 

 country in reference to their appearance on trees 

 in early spring, that it would be pedantic to re- 

 ject it ;. besides, I have already used it in speaking 

 of the origin of branches. But as the term bud is 

 also employed to denote the separate flower before 

 it blows, and as the purposes of science are better 

 attained by using a word applicable to the object 

 only which it is intended to present to the mind, 

 I shall employ the term hybernaculum as syno- 

 nimous with bud, in treating of this part of our 

 subject. 



A HYBERNACULUM may be defined : an organic 

 body which sprouts from the surface of different 

 parts of a plant, enclosing the rudiments of the 

 new shoot ; and which is capable of evolving a new 

 individual perfectly similar to the parent. This is a 

 modification of the definition of Gsertner *, which 



* " An organic body generally sprouting from the surface 

 " of a plant, without previous fecundation ; in the beginning 

 " distinct from the peculiar and permanent membranes of the 

 " plant ; but which, in a certain time, either becomes a part 

 " of the parent, or separates from it, and by the increase of its 

 " own substance becomes a new plant, closely resembling the 

 " parent." Gartner de Fructibus Plant, p. 3.
