Abstract
IN a chromatographic analysis of twenty-one putative hybrids of Baptisia viridis × B. leucantha each of the hybrid types contained in the leaves 4 distinctive substances which were absent from the leaves of more than 25 specimens of each of the pure parental species examined. The 4 hybrid-specific components were distributed in a novel pattern and reacted characteristically in ammonia vapour when observed in ultra-violet light. Accordingly, they were considered to be bona fide hybrid-specific substances1. Since there has been considerable interest in the appearance of new components in hybrids, and attendant theoretical implications touch on aspects of plant biochemistry and evolutionary mechanisms, it is important to establish conclusively that such substances actually are hybrid-specific and, if possible, their identity.
