THE FIRST BOOK OF BOTANY. 
The lobe at the apex of a leaf, which is called the 
terminal lobe, and those at the base, called the basal 
lobes, have to be first noticed. Are they alike in the 
same leaf? Are they like the other lobes of the 
leaf? 
Fig. 31. Fig. 32. 
Observe whether the lobes are round like Fig. 31, 
or sharp like Fig. 32. 
Add the question Lobes ? to your schedule, and 
when you answer it in regard to a leaf, say how many 
lobes it has, and whether they are round or sharp. 
If the terminal or the basal lobes are larger, smaller, 
or different in shape from the others, you can put 
down the fact in answer to the questions Base ? and 
Apex ? When feather-veined leaves are lobed, they 
are said to be pinnately lobed (from pinna^ a feather), 
and palmate-veined leaves, Fig. 32, are said to be pal- 
mately lobed. 
Look your specimens over once more, to see 
whether the spaces between the lobes are alike in all 
of them. The space between two lobes is called a 
sFnus. Look at the names given to the different 
sinuses in the following figures.
