PI. 294. 
AVOCADO TREES IN THE CHOTA VALLEY, NORTHERN ECUADOR. 
(Persea americana Mill., S. P. I. Nos. 54270 to 54273.) 
This small, arid valley, which lies at an elevation of about 5,000 feet near the northern boundary 
of Ecuador, contains some of the best avocados in tropical America. Most of them are of 
the Mexican race, a few are West Indian, and a few may be hybrids. A set of the most 
promising ones has been introduced for trial in the United States. The trees in the center 
of the photograph are avocado trees. (Photographed by Wilson Popenoe [telephoto lens],
