87. Where Buds Are. — Buds are borne in the axils 

 of the leaves, — in the acute angle that the leaf makes with 

 1^ the stem. When the leaf is grow- 

 ing in the summer, a bud is form- 

 ing above it. When the leaf falls, 

 the bud remains, and a scar marks 

 the place of the leaf. Fig. 57 

 shows the large leaf-scars of ailan- 

 thus. Observe those on the horse- 

 chestnut, maple, apple, pear, bass- 

 wood, hickory, or any tree or bush. 

 88. Sometimes two or more buds 

 are borne in one axil: the extra 

 ones are accessory or supernumerary s 8 . Termi- 

 buds. Observe them in the Tar- between 

 tarian honeysuckle (common in b W u°d° th — 

 yards), walnut, butternut, red Cum " lt ' 

 maple, honey locust, and sometimes in the apricot and 

 peach. 



89. Shoots of many plants bear a bud at the tip: this 

 is a terminal bud. It continues the growth of the axis in 

 a direct line. Very often three or more buds are clustered

at the tip (Fig. 58); 

 and in this case there 

 may be more buds than 

 leaf-scars. Only one of 

 them, however, isstrictly 

 terminal. 



90. Bulbs and cabbage 

 heads may be likened 

 to buds: that is, they 

 are condensed stems, 

 with scales or modified 

 leaves densely overlapping and forming a rounded body. 

 (Fig. 59.) They differ from true buds, however, in the fact
