Acknowledgments The preparation of this Checklist has been aided by the many persons who have supported and assisted in the building of the Herbarium of the University of Florida, the major repository of information upon which this list is based. I have drawn freely upon the published work and upon personal cor- respondence with botanists who have dealt with the South- eastern flora. The late Professor Erdman West and Dr. Robert K. Godfrey, in particular, have contributed to my understand- ing of many genera.
