The number of foliage-leaves present upon a developed shoot 

 is often indicated in the bud, but in some plants, especially those

Ex. 21. — Cut longitudinal sections through a Brussels sprout and the ' heart ' 

 of a cabbage. Note the stem, leaves, and axillary buds within. 



Ex. 22. — Examine with a lens longitudinal sections of the buds of sycamore, 

 horse-chestnut, oak, beech, and other trees.

5. The vegetative shoots of plants usually end in 

 terminal buds, and an examination of almost any kind of 

 plant shows that not only are buds present at the tips of the 

 stems, but on their sides as well. These lateral buds arise 

 ordinarily in the upper angles formed where the leaf-bases and 

 stem join each other. The angles are termed the axils of the 

 leaves, and the buds are designated axillary buds. Most fre-
