The Dago Haya, the Best Tropical Yam, from the Island of 

 Guam, Growing at Miami, Fla. (Dioscorea alata L., S. P. I. 

 No. 39705.) 



The true yams constitute an important group of starchy tuberous-rooted food plants 

 and should not be confused with certain varieties of sweet potatoes that are called 

 yams in our Southern States. They should be grown and used largely in those 

 warm regions of the world where they will thrive and into which people demanding 

 white potatoes have to import them from cooler regions. In the island of Trinidad 

 the production of the yam, cassava, taro, and other starchy root crops has been so 

 increased during the war that the necessary demands on the wheat supply of the 

 world and on transportation for carrying flour and potatoes to that island have been 

 materially reduced. (Photographed by Edward Simmonds, October 20, 1916;
