80 ELEMENTS OF BOTANY. 
himself are not large enough to show in the most obvious 
way the relation of the parts and their real nature. 
Fortunately, it is easy to 
obtain a gigantic bud which 
illustrates perfectly the struc- 
ture and arrangement of buds 
in general. 
Examine and sketch a cabbage 
which has been split lengthwise 
through the centre! and note

(b) The crowded leaves which arise 
from the stem, the lower and outer 
ones largest and most mature, the 
upper and innermost ones the smallest 
of the series. 
Compare the section of the cabbage 
with Fig. 60. 
Most of the buds so far con- 
sidered are leaf-luds, that is, 
their inner parts will develop 
into leaves, and their central 
axes into stems; but some were 
mixed buds, that is, they con-

in other cases, as in the culti- 
vated cherry, the difference in form is but slight. 
1 Half of a cabbage will be enough for the entire division.
