WINTER CONDITION OF SHOOTS AND BUDS

Butternut 



PcacH 



that as they develop into shoots the branching system of a limb 

 presents a flattened outline, which is more marked when the 

 leaves are present, since shoots and leaves lie in nearly the same 

 plane. On either side of the leaf 

 scar is a minute scar, the stipule 

 scar, which marks the' location of 

 small delicate outgrowths (the 

 stipules) at the base of the leaf 

 stalk, which fall away soon after the 

 opening of the leaves in the spring. 

 The larger bud at the end of the 

 stem is situated in the axil of a leaf 

 scar. It is, therefore, an axillary 

 terminal bud. Close to it and on 

 the opposite side from its leaf scar 

 is a small scar, which marks the 

 point where the true terminal bud 

 was seated and which has fallen 

 away. The shoot of the elm has 

 therefore indefinite growth. In the 

 spring, when the new shoots de- 

 velop, the axillary terminal bud 

 and the bud next below but on the 

 opposite side of the shoot, develop 

 with nearly equal vigor, and thus 

 diverge, producing a fork. The 

 result of this is the diffuse or deli- 

 quescent stem of the elm (see types 

 of stems, paragraph 71). 



115. Shoots of the butternut. 

 The terminal young shoots of 

 the butternut are of a dull brownish 

 green color, while the older shoots are a darker brown. The 

 surface is dotted with minute gray or whitish points, the lenticels 

 (paragraph 191). The terminal shoot can be determined by the 

 prominent apical bud, which is long, conical and slightly curved.
