region in 1875 he does not include this tree. An examination of his 

 herbarium material showed no specimens of this tree either from Indiana 

 or Illinois. It is fair to presume if he had been acquainted with the 

 tree he would have had it represented in his herbarium. Since the white 

 elm is frequently called water elm, as well as the planer-tree, it is 

 easy to understand how confusion might arise in separating these trees 

 by non-professional people. 



Morus nigra Linnaeus. BLACK MULBERRY. This species is reported 

 by Phinney 1 as one of the "more important and common forest trees 

 observed in Delaware County." He also enumerates Morus rubra. A 

 splendid example of careless work. This species is reported by Brown 2 

 for Fountain County, and by McCaslin 3 for Jay County. These authors 

 reported this species as a native forest tree. Since this species is 

 not a native of the United States the citations no doubt should be re- 

 ferred to our native mulberry, Morus rubra (red mulberry). 



Ilex opaca Alton. HOLLY. This species was included in Coulter's 

 Catalogue of the Plants of Indiana on the authority of Robert Ridge- 

 way. I find no reference to this species in the writings of Ridgway. 



In Shawnee Park on the west side of Louisville, Kentucky is a large 

 tree of this species. I was told that it was a native. A timber buyer of 

 Tell City told me that there was a native tree on his grandfather's farm 

 in the southern part of Perry County. Since this species has been re- 

 ported for Grayson County, Kentucky, which is less than forty miles 

 to the south, it is quite probable that a Jew trees were found as far north 

 as Indiana. 



Acer pennsylvanicum Linnaeus. MOOSBWOOD. The only record 

 of this species occuring in Indiana is in a report of the Trees occuring 

 along the Wabash River by Prince Maximilian. Since the report does 

 not definitely state where the species was observed or how frequently 

 it occured and since the greater part of Maximilian's time was spent 

 on the Illinois side of the Wabash, it is more than likely that he observed 

 it on the Illinois side of the Wabash. While Indiana is within the 

 possible range of the species, it has not been discovered since. If not 

 extinct in our area it is most likely to be found among the hills of the 

 southern counties or in the vicinity of Lake Michigan. Robert Ridg- 

 way says that he and Dr. Schneck saw it growing in a wooded cove 

 near a cavern called Flory's Cave in Johnson County, Illinois. 



Nyssa aquatica Linnaeus. TUPELO GUM. Several early authors 

 erroneusly reported Nyssa sylvatica as this species. This species in- 

 habits deep swamps. Dr. Schneck and Robert Ridgway, recognized
