Ephebe lanata - cited from Boone Co. by Berry (1936, 1937); the 1937 report is the basis for the literature report in Gier & Kendrick (1972). This taxon was also mapped from the SE1/3 Mo. by Hale (1969, 1979). No confirming specimens have been located. Given the tenuous nature of these reports, the species is provisionally excluded from the flora.
