=Nyssa aquática= Linnæus. Tupelo Gum. Several early authors erroneously reported _Nyssa sylvatica_ as this species. This species inhabits deep swamps. Dr. Schneck and Robert Ridgway, recognized authorities and best acquainted with the swamp area of the southwestern counties, at first thought it was a member of our flora, but later decided that it should be excluded. Michael Catt, 83 years old, who lived nearly 75 years about three miles west of Decker on the border of the cypress swamp in the south part of Knox County, told me that he is positive that the tupelo gum was an occasional tree in the cypress swamp west of Decker. =Fraxinus caroliniàna= Miller. Water Ash. This species was included in Coulter's Catalogue of Indiana Plants upon the authority of Dr. Schneck. It is asserted that specimens were sent to Missouri Botanical Gardens for verification. The writer has carefully examined all the specimens of _Fraxinus_ in the Missouri Botanical Gardens, and all of Schneck's specimens in the herbarium are now correctly named _Fraxinus profunda_. Since this species is not in our range it should be dropped from our flora.
