had no recollection of the location of the tree. Since the record 
could not be verified it is thought best to drop it for the present. 
J. M. Coulter reports it from Jefferson County, and A. H. Young, 
who also reported on the flora of Jefferson County, fails to mention 
it. The preceding record may have been made from a cultivated 
tree, or it may have been mistaken for Populus grandidentata, which 
is not reported and is within range of the county. Baird and Tay- 
lor also reported it from Clark County in a flora of Clark County 
but failed to report Populus grandidentata, which is locally frequent. 
Hicoria aquatica (Michaux) Britton. Water Hickory. (Carya 
aquatica (Michaux) Nuttall.) This is listed as one of the principal 
trees occurring along the Wabash in the Coblenz edition of Prince 
Maximilian’s travels in North America. It is recorded as ‘‘Water 
Bitternut (Juglans aquatica). If it occurs in our area it most 
likely would be found in the extreme southwestern counties. It 
has been reported from Gallatin County, Illinois, bordering Posey 
County on the west. 
There are two other records of its occurrence in the State, which 
are doubtful. Ryland T. Brown reported it in a list of the prin- 
cipal trees of Fountain County in a report of the geology of Foun-’ 
tain County. AHicoria laciniosa, which is sometimes called swamp 
hickory and which is more or less frequent in the county, he failed 
to report. It is believed this reference to Hicoria aquatica should 
be referred to laciniosa. B.C. Hobbs also reported it as common 
in Parke County in a short list of the principal trees. He named 
only four of the five or more species of hickory that occur in the 
county, and it is believed, since he was no botanist, that he confused 
the names. Elliott in his Trees of Indiana gives ‘‘Carya aquatica” 
as common, but no doubt this reference should be transferred to 
some other species. 
Hicoria myristiceformis (Michaux) Britton. Nurvec Hicxkory. 
This tree also was reported by Prince Maximilian as occurring 
along the Wabash River. The known range of the species is from 
North Carolina to Arkansas, and for this reason the species is not 
included in this list. 
Castanea pumila (Linneus) Miller. Curnauarin. This species 
was given a place in our flora in Coulter’s catalogue upon the author- 
ity of Sargent, Ridgway and Schneck. Ridgway, in giving an 
additional list of the trees of the lower Wabash Valley (Proc. U. S. 
Nat. Mus. 17:415), says: ‘‘There is some doubt as to No. 16, Cas- 
tanea pumila, which is given on Prof. Sargent’s authority; but 
there is a possibility of an error having been made from the cir-
