THE LEAF.

and describe as many leaves as you should, you will 
have abundant use for every one of the terms here 
given. 
For the present, put aside your lobed leaves. 
The first eighteen diagrams are divided into three 
groups : 
(a.) Figures of leaves that are broadest in the 
middle. 
(5.) Figures of leaves that are broadest at the base. 
(c.) Figures of leaves broadest at the apex. 
You will know at once which of these groups to 
compare a leaf with. 
Do not expect to find your specimens exactly like 
the figures. Give them the names of the forms they 
most resemble. 
When a leaf seems to be about equally like any 
two figures, join together the names of these two 
forms in describing it, as seen in Fig. 42. 
(a.) LEAVES THAT ARE BROADEST IN THE 
MIDDLE.
