BUDS 
Position of Buds. — Buds are either terminal, located at the 
tip of the stem: or lateral, occupying positions on the side of the 
stem. (Fig. 185.) The plumule is the first ter- 
minal bud of the seedling. The terminal bud is 
usually larger and stronger than the lateral ones, 
and its shoot usually makes more growth than the 
shoots of lateral buds. 
Lateral buds usually occur in the 
leaf axils and when so located are 
called axillary buds. In many plants 
extra buds called accessory buds oc- 
cur, which may stand just above the 
axillary bud, as in the Butternut, or 
on either side of it, as in the Box-elder. 
(Fig. 186.)

Buds, called adventitious buds, often 
spring from stems, from roots, or

an important part in the formation 
of roots, and sometimes in the for- 
mation of stems. Thus in the propa- 
gation of Sweet Potatoes, adventitious 
buds are depended upon to develop 
the new plants. In Figure 187 is 
shown the sprouts springing from the 
adventitious buds on the stump of 
the Basket Willow. In this case the 
sprouts are harvested after they be- 
come large enough to be woven into 
baskets, and a new lot of sprouts is 
then produced from other adventitious 
buds. In this way one can secure 
many crops of stems from one stump. 
On the other hand, adventitious buds are often a source of 
trouble, as in the clearing of ground where the sprouts develop- 
ing from the adventitious buds on the stumps and roots tend to
