A Tropical Solanum
This is a cousin of the tomato and potato, and it came to Mr. Burbank's garden from Brazil; at least its ancestors did. The variety here shown has been greatly improved through selection, and has been made to give up the major part of the annoying spines that its progenitors wore. The plant bears a tomato-like fruit, and Mr. Burbank contemplates attempting to hybridize it with the tomato. The result should have great interest.
