A Relative of the Sunberry
These are blossoms of a South American parent, the Solanum jasminoides, sometimes called the potato plant. The blossoms of this plant closely resemble those of the sunberry, although the plants are very far from identical in other regards. The relationship between the two is not very close, but the similarity of blossom gives another illustration of the way in which a character may be transmitted and modified into different strains of plants from a different ancestor.
