86. WHERE BUDS ARE. Buds are borne in the axils 

 of the leaves, in the acute angle which the leaf makes 

 with the stem. When the leaf is 

 growing in the summer, a bud is 

 forming above it. When the leaf 

 falls, the bud remains, and a scar 

 marks the place of the leaf. Fig. 

 53 shows the large leaf -scars of 

 ailanthus. Observe those on the 

 horse-chestnut, maple, apple, pear, 

 basswood, or any tree or bush. 



87. Sometimes two or more 

 buds are borne in one axil : the 

 extra ones are accessory 

 supernumerary buds, 

 them in the Tartarian honeysuckle 

 (common in yards), walnut, but- 

 ternut, red maple, honey locust, and sometimes in 

 apricot and peach. 



88. 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. 54); and in this 

 case there may be more 

 buds than leaf - scars. 

 Only one of them, how- 

 ever, is strictly terminal. 



89. Bulbs and cabbage 

 heads may be likened to 

 buds : that is, they are 

 condensed stems, with 



scales or modified leaves 55 - A ^ ailtic bud.-cai>bage.
