This paper serves to indicate the ease with which hybrids may be produced between individuals of homoploid species under controlled conditions. An annotated list of suspected hybrid combinations observed in the wild is presented.

This paper is one of a series based on a cooperative effort to solve the problems involved in the horticultural development and taxonomic interpretation of the North American blueberries, cranberries, and related groups.

This is a description of three new varieties of blueberry - the Atlantic, the Pemberton, and the Burlington. Information as to how these varieties came about is provided.
