BUDS AND BRANCHES 



z^7 



Axillary buds are 

 leaves. Buds regu- 

 larly arise in this 

 position; in fact, the 

 presence of buds in 

 their axils is one of 

 the ways in which 

 leaves are recognized. 

 Compound leaves are 

 leaves which are sub- 

 divided into leaflets; 

 these leaflets often 

 have the appearance 

 of true leaves, but 

 - their real character 

 is revealed by the 

 absence of buds at 

 their axils. (See 

 Figure 65.) Axillary 

 buds may become 

 terminal buds. Thus 

 in the lilac the buds 

 in the axils of the first 

 pair of leaves below 

 the apex develop 

 more vigorously than 

 the terminal bud ; 

 in fact, the terminal 

 bud may not develop 

 at all. The result is 

 that with each new 

 season a forking oc- 



those which appear at the axils of 



Fig. 65. — Twig o{ the ash, one compound leaf 

 showing. Note the buds in the axils of the leaves 

 and the lack of them in the axils of the leaflets. 

 The enlarged bit of stem at the right shows lenti- 

 cels, and also the scars left by the leaves of the 

 preceding season. Note the alternating arrange- 

 ment of the attachment of the leaves.
