52 BUDS AND STIPULES 



hollow of the bud ; while the final arrangement of the 

 leaf in the bud is shown in figs. 17 and 18. 



In the axillary buds, as a rule, the outer covering 

 consists of two stipules, the rest of the leaf not being 

 developed (fig. 83). Sometimes, however, at the base 

 a small projection may be seen (fig. 84), which is a

rudiment of a petiole. Sometimes this is rather more 

 developed (fig. 85), and sometimes a rudimentary blade 

 also appears (fig. 86). 



The reversal of the leaf in the bud, owing to the 

 length and early development of the petiole, is* very 

 unusual. In Amicia Zygomeris the leaf is bent, but 

 only forms a right angle with the petiole. 



Rose 



The leaf of the Rose (see ante, fig. 58, p. 46) is more 

 complicated. It commences as a small knob at the 

 side of, and immediately below, the growing-point. 

 When this knob has reached a certain length it pre- 

 sents two lobes (fig. 87), which arise almost simul- 

 taneously. 1 The upper of these becomes one of the 



1 According to Schacht, however, the stipule appears first.
