Eq'uitant. —When opposite conduplicate leaves 
overlap each other at the base. 
Leaves are always arranged in one or other of the 
two ways called valvate and imbricate. 
The Vai 'vate arrangement is seen when the edges 
of corresponding leaves barely touch each other. 
The Imbricate arrangement is seen when the 
edges of the leaves overlap each other. Fig. 92 
shows an imbricate arrangement.
