112 THE GRAPE CULTURIST. 



is termed the shoulder. Fig. 36 shows a bunch of 

 grapes, as produced from a divided productive tendril. 

 This form of bunch might be appropriately called the 

 natural form, and certainly it seems to carry with it 

 more of the general idea of a bunch of grapes than many 

 of the other forms which are occasionally seen. 



Sometimes a bunch is divided into several small 

 clusters, which partly or entirely surround the main 

 body ; when this occurs they are called clustered bunches 

 instead of shouldered. But as the bunches of fruit are 

 more or less variable in the same kind of grape, it is not 

 expected, in describing a variety, that more than their 

 general character can be given. 



Buds. Buds are embryo plants, for they contain 

 all the elements necessary to insure or secure, when 

 removed from the parent, a distinctive, individual exist- 

 ence. They contain the rudiments of leaves and stem 

 in a miniature form, and growth is but the development 

 of these individual parts. 



The principal buds of the vine are situated at the 

 axils of the leaves only, and are never found upon any 

 other part of the stem. They are naturally single that 

 is, produce but one shoot ; but vines, when under culti- 

 vation, often show a disposition to produce a number of 

 shoots from a bud ; or, in other words, the buds divide 

 indefinitely, and each division is capable of producing a 

 distinct cane. Fig. 35 e and c show a double bud; 

 such examples are often seen upon trained vines, and 

 nearly every bud, upon vines that have been checked 

 during growth, will show the double bud, both of which 

 will often produce a shoot, but seldom of uniform 

 strength. If a shoot that has started from a bud is 

 broken off, others will immediately start from near its 

 base. These are said to grow from accessory buds. 

 They are sometimes incorrectly called adventitious ; but 

 adventitious buds do not exist upon the stem of the 

 vine, as they do upon most other woody plants.
