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 wasan 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 shauld be transferred to that species. 
The published records are as follows: Gibson, Knox and Posey 
(Schneck); Knox (Thomas); Miami (Gorby). 
Planéra aquatica (Walter) J. F. Gmelin. PLANER-TREE. WATER 
Eim. 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 Treesof North America’”’, Vol. 9, U. S. Census 
Report, 1880, page 124. Dr. Schneck spent a lifetime along tke 
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. 
Tlex 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 Linnzeus. Moosswoop. 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 Jndiana 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.
