92 Eleventh Annual Report 



New York, south to Florida and west to Texas, and north to south 

 ern Kentucky. If it occurs within our area it no doubt would have 

 been found by Dr. Schneck, who was an enthusiastic student of the 

 oaks. He reported it as occurring in the lower Wabash in his early 

 writings, but his herbarium contained no specimens. The writer 

 while in search for this species in Posey County met three men in 

 widely separated parts of the county who were acquainted with the 

 species in the South and they said they had never seen it in Indiana. 

 One of the men was an old man who had spent his boyhood in 

 Arkansas and was well acquainted with the willow oak before he 

 came to Indiana. It is believed what has been reported for Phellos 

 has been narrow-leaved forms of imbricaria (Shingle Oak), and that 

 the records should be transferred to that species. 



The published records are as follows: Gibson, Knox and Posey 

 (Schneck); Knox (Thomas); Miami (Gorby). 



Planera aquatica (Walter) J. F. Gmelin. Planer-tree. Water 

 Elm. This tree was included in Coulter's catalogue upon the 

 authority of Sargent, who includes Indiana in the range of the 

 species in his "Forest Trees of North America", Vol. 9, U. S. Census 

 Report, 1880, page 124. Dr. Schneck spent a lifetime along the 

 lower Wabash bottoms and very carefully preserved specimens of 

 all the flora of the region where this species is reported to occur. 

 In his report of the flora of this 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 fre- 

 quently 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. 



Ilex opaca Aiton. Holly. This tree was included in Coulter's cat- 

 alogue on the authority of Robert Ridgway, who said it "had been 

 listed for southern Indiana." It has not been possible to establish 

 a reliable State record for the species, so it is dropped from the 

 present list. 



Acer pennsylvanica Linnaeus. Moosewood. The only record of 

 this tree occurring in Indiana is in a report of the trees occurring 

 along the Wabash River by Prince Maximilian. 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 along 

 the hills of the southern counties. Robert Ridgway says that he 

 and Dr. Schneck saw it growing in a wooded cove near a cavern 

 called Flory's Cave in Johnson County, Illinois.
