RESTING BUDS 



. Buds of the 

 Hickory. 



Sometimes 



29. The most conspicuous buds are the scaly resting 

 buds of most trees and shrubs of temperate or cold 

 climates. When these are formed at the 

 end of a stem or branch, they are referred 

 to as terminal buds. In the angle, or axil, 



of nearly all the leaves 



others are found, termed 



axillary or lateral buds 



(Fig. IT). 



30. Accessory or su- 

 pernumerary buds. — 

 There are cases where 

 two, three, or more 

 buds spring from tlie 

 axil of a leaf, instead 

 of the single one which 

 is ordinarily found there, 

 they are placed one over the other, as 

 in the Aristolochia, or Pipevine ; and 

 in Pterocar3^a (Fig. 18), Avhere the 

 upper bud is a good way out of the 

 axil. In other cases three buds stand 

 side by side in the axil, as in the Red 

 i\Iaple. 



31. Formation of winter buds.— 

 Such plants as prepare for winter by 

 the production of winter buds form 

 them earl}^ in the foregoing summer. 

 In many woody plants the axillary 

 buds do not show themselves until 

 spring ; but if searched for, they may 

 be detected, though of small size, 

 hidden under the bark. Sometimes, 

 though early formed, they may be 

 concealed all summer long under the 

 base of the leaf stalk, Avhich is then

The accessory buds 

 of Pterocarya 

 RhoifoUa, some- 

 what above the 

 axil, and already 

 partially devel- 

 oped in the first 

 summer.
