The Leaf of Colliquaya odorifera, Molin. 
is very lax and is composed of ordinary and secretory cells in 
approximately equal numbers. The secretory elements here are 
of two kinds, ordinary cells which have assumed the secretory 
function, and idioblasts with denser darker-coloured contents. In 
association with these long series of cells sometimes occur (Fig. 
23). 
Glandular Structures .—'These are found on the leaf-teeth and 
form the most prominent and characteristic feature of the leaf.
