Frequency of occurrence changes are cited for 154 rare and infrequent taxa of herbaceous vascular plants listed by Edwin L. Moseley in 1928. Of these taxa, approximately 47% are less frequent now (1978) than 50 years ago. Twentysix percent exhibit the same frequency of occurrence and 27% arc more frequent than they were 50 years ago. Approximately 50% of these rare and infrequent taxa are widespread in distribution, 35% are northern, 7.5% are southern, 6% are western and 3% are originally from the Atlantic Coastal Plain. One hundred thirteen new taxa are cited that were not reported by Moseley 50 years ago.
