Abstract
THE importance of the study of natural hybridization is obvious in view of the large part it plays in the process of evolution. There have been considerable differences of opinion, first as to the possibility of recognizing natural hybrids and, secondly, as to the status of the parents once the possibility of hybridization has been established. We are not concerned here with the second controversy, for it must be recognized, now, that the existence of hybrids both within and between species is well substantiated. Although hybrids are one of the banes of the taxonomist, their frequent occurrence in Nature makes it important that they should be recognizable without doubt. Further, when such recognition is possible they cease to be a bane.
