LEAF VEINS 
OME time ago you learned that 
from the stem of a plant you 
could guess the number of seed leaves 
which it brought into the world, and 
that in the same way from the seed 
leaves you could guess what kind of a 
stem it would build up. 
From the way in which a leaf is 
- veined you can guess both of these 
things. You can guess what sort of a 
stem belongs to the plant, and with how 
many seed leaves it began life. 
When the little veins run in and out, ae Vel 
form- ing a sort of network, we say /\\\~ Py ai 
that i \ the leaf is ‘‘net-veined.” eee?
