BUDS

gem. The same fact is apparent in the buds of the Cherry, 

 Peach, Lilac, and perhaps all other plants. 



The buds of grasses and grains are Fi s- 153. 



distinguished by an outer single scale, 

 between the stem and the bud, while 

 plants of other classes, or tribes, have 

 two scales on opposite sides of their 

 buds, either distinct or united. 



The cuts, Fig. 153, represent this ar- 

 rangement, a, a, being grass buds covered 

 with their scales ; b, showing the naked 

 buds, the scales being removed. 



The buds which enclose both leaves 



and flowers are also distinguished by their forms, but the 

 difference is not so considerable as those which contain only 

 the one, or the other, this shape being a medium between 

 the others. 



In conformity to their different contents, buds have been 

 arranged into three species, namely, 



1. Gemma folifera, or leaf gems. 



2. Gemma florifera, or flower gems. 



3. Gemma mixta, or mixed gems. 



Buds, though connected with the parent stalk, and produced 

 by the vital action of the plant of which they are the progeny, 

 are still, in themselves, complete individuals. 



We have seen above that the pith of the new bud is not a 

 continuation of the old, but a new production. That there is 

 no necessary connection between the tree and bud after the 

 latter is formed, is proved from the fact that if a bud be cut 

 from one tree and inserted into another, it will grow into a 

 perfect branch, and bear fruit in the same manner that it 

 would have done on the parent tree. How far with respect 

 to classes and orders this may be carried into practice, we 

 know not. It is certain however that in some instances 

 plants of very different characters will grow on each other, 

 as in the well-known instance of the Quince on the Thorn 

 bush. Plants of the same natural orders we believe may be 

 budded successfully to almost any extent. Thus the Potato 



What peculiarity is there in the buds of the grasses'! How have buda 

 been arranged into species ? Are buds complete individuals, or parts o., 

 the parent ?
