The cellules of the leaf are minutely papillose, and when viewed 

 from above each marginal cellule usually shows two salient papillae : 

 it is this which gives the edge of the leaf the appearance of being 

 granulated. Is it caused by the pressure of the grains of chloro- 

 phyll on the delicate walls of the cellules ?
