Net-veined leaves are borne by plants which brought 
into the world more than one seed leaf; and with the 
net-veined leaf we can expect to find that 
stem which comes with more than one seed 
leaf, —a stem where the skin or bark, the 
woody rings, and the soft central pith, are 
clearly separated one from another. 
But a leaf such as that in Fig. 143 or that 
in Fig. 144, where the veins do 
o 
not branch off in a network, but 
run in unbroken lines side by iN 
side, —such leaves as these tell \\ | \ 
ae you that they are borne by plants V// : 
which started life with only one seed leaf, ) 
and which have such a stem as the corn- ap 
stalk, where you see no woody rings or Za 
central pith. WS 
These leaves are called “ parallel-veined.” & 
I fear that you find all this a little diff- Fic. 144 
cult to understand and to remember; but if you read it 
patiently, when you study the botany for older children, 
I think it will come back to you and make your lessons 
easier.
