90 Eleventh Annual Repokt 



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 ako 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 

 MaximiHan'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, IlHnois, 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 hst of the prin- 

 cipal trees of Fountain County in a report of the geology of Foun- 

 tain County. Hicoria 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 myristicseformis (Michaux) Britton. Nutmeg Hickory. 

 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 (Linnaeus) Miller. Chinquapin. 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-
