Sci. 1917:404:1918 for Cowles. I regard this as an error. See discus- 

 sion under Abies canadensis on page 290. Since the range of the species 

 is to the north of Indiana, it is here proposed to drop it from our flora. 

 It should be looked for on the "divide" in Steuben County and about 

 Lake Michigan. 



Populus candicans Aiton. BALM OF GILEAD. This species has 

 been included in a few local floras, but it is believed that it has not yet 

 escaped from cultivation. Phinney 1 gives it as "an important timber 

 tree of Delaware County," which is an error. 



Populus nigra var. italica Du Roi. LOMBARDY POPLAR. Reference 

 is made to this tree by Blatchley 2 , Meyncke 3 and Nieuwland 4 but 

 it is scarcely more than an accidental escape. 



Carya aquatica Nuttall. WATER HICKORY. This species is listed 

 as one of the principal trees occuring along the Wabash in the Coblenz 

 edition of Prince Maximilan'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 5 reported it in a list of 

 the principal trees of Fountain County in a report of the geology of 

 Fountain County. Carya 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 Carya 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. 



Carya myristicaeformis Nuttall. 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. 



Betula lenta Linnseus. BLACK BIRCH. This species has been re- 

 ported for Indiana as occurring in Fulton, Gibson, Miami, Noble, 

 Posey, St. Joseph and Steuben Counties. Sargent 6 says: "This species

5 It is said that this list and that of Hobb's list of trees of Parke county were prepared by 

 obtaining from farmers a list of the common names of the trees to which they attached 

 botanical names.
