A Brazilian Solanum
This is a relative of the potato and tomato that came originally from Brazil. The fruit somewhat resembles the tomato, although of a quite different species. This picture shows the fruit of the new Solanum in a transition stage, after Mr. Burbank had worked on it for a few generations, but when it was by no means perfected.
This image is from: Luther Burbank: his methods and discoveries and their practical application. Volume 2 Chapter 9
