During the summer of 1939 while the writer was collecting plants in preparation of a flora of McCreary County, Kentucky, an unusual mint was collected near the Alum Creek Ford of South Fork River in that country. The plants were quite abundant in that locality and several specimens were taken during the late summer and fall. All attempts at identification proved fruitless and a specimen was submitted to Dr. Carl Epling, an authority on the family. He replied that he did not know the plant but, was sending it to Dr. F. R. Fosberg at the National Herbarium. A few weeks later Dr. Epling wrote that it had been identified as Mosla lanceolata Max., an old world species and that this collection was the first report from the Western Hemisphere.
