FIG. 336. Cacao tree (Theobroma Cacao), growing in Rio Hondo. Costa Rica. In 

 the illustration is shown the peculiar habit of this tree in producing large, ovoid, fleshy 

 fruits on the main axis or trunk, as well as on the older branches. When Cortez conquered 

 Mexico he found the Aztecs using Cacao seeds to make a beverage; this was later introduced 

 into Europe, previous to either coffee or tea. Reproduced by permission of The Phila- 

 delphia Commercial Museum.
