Vernation* 
Vernation is the way m which leaves are folded, 
rolled, or arranged in the bud. 
Fresh buds are constantly appearing throughout 
the growing season at the tips of steins and in the 
axils of leaves. Observe the way in which the parts 
of these buds are packed together. Observe them 
when they are just opening. If you are watchful, 
you will be sure to find them at a moment when the 
growing leaves have not yet lost the shapes they had 
while packed in the bud. 
The chief ways in which leaves are rolled and 
folded in buds are shown in the following illustrations.
