PLATE i 
Tobacco plant of flue-cared type affected with sand drown. Note that the plant as 
a whole and the individual leaves have attained normal size and shape and the leaf 
surface is relatively smooth. The disease begins in the lower leaves and at the tips 
of the leaves. The veins retain their green color long after the leaf lamina becomes 
bleached. The leaf lamina usually does not die in local areas or spots as in potash 
hunger.
