My specimens were determined by E. B. Williamson who for many years 
has cultivated many species of Iris, and who has made a special study of 
the genus. Live specimens from the localities mentioned were sent to him 
and have been cultivated by him in his garden ever since. Among the many 
species of Iris he has under cultivation are Iris foliosa, Iris versicolor and 
Iris hexagona. When the three species are grown side by side it is easy 
to see that all are quite distinct. It is believed that all references to Iris 
hexagona in Indiana should be referred to Iris foliosa.
