PLATE S3 
A plant of the Pima variety of American Egyptian cotton, strain 5-3, photographed 
in August when the lowest bolls were nearing maturity. This plant represents the 
ideal which is sought in the breeding work with this variety, being free from vegetative 
branches or “limbs” and having fruiting branches well furnished with bolls at every 
node from near the base to the top of the stem.
