Snow-on-the-Mountain 
This odd plant is shown here to illustrate the necessity 
of studying not merely the form of a plant but the forces 
within it. Jt receives its name because when il blooms its leaves 
begin to turn while. The purpose of this, Mr. Burbank says, is to 
help guide the insects to the blossom in order to insure reproduction. 
It will be noted that the leaves which do not lead to blossoms remain 
green, while those which surround the blossoms form brilliantly 
illumined pathways for the insects. Few plants give outward evi- 
dences of their processes so clearly as this—but the forces 
of heredity and environment are there—none the less 
—and it is these forces which we must study 
if we are to help plants to improvement,
