Nyssa aquatica Linneus. Turreto Gum. This species is in- 
cluded in Coulter’s catalogue of Indiana plants and has been 
reported from many widely separated counties. But few speci- 
mens were preserved upon which county records were made. Two 
of these have been examined which showed that they were variable 
leaf specimens of Nyssa sylvatica (Sour Gum), no doubt taken 
from a vigorous branch or a thrifty young tree. It is believed that 
all the locations of this species occurring in the State should be 
referred to Nyssa sylvatica. This species has been a puzzle to the 
systemist who is not acquainted with both species, and so far as 
is known no one of those who reported aquatica for the State was 
acquainted with it at the time the report was made. The-tree is . 
said to grow in cypress swamps from southern Virginia west to 
Missouri and up the Mississippi Valley to southern Illinois. If it 
occurs in our area it would be found in the cypress swamps along 
the lower Wabash. Dr. Schneck reported it for this region in the 
early years of his botanical work, but on May 20, 1902, on a speci- 
men of Nyssa he makes the following note: ‘I now believe all the 
forms of Nyssa are sylvatica.’”’ This note is made to cover the 
forms of the Wabash Valley. Robert Ridgway also reported it 
for Knox County in his earlier publications, but in a letter from 
him dated November 11, 1911, he says, ‘‘You will observe that Nyssa 
aquatica is not given in my two catalogues, and I think the Sheu 
may safely be omitted.” 
The published records of its distribution are as follows: Dear- 
born (Collins); Delaware, Jay, Randolph and Wayne (Phinney); 
Franklin (Haymond) and (Meyncke); Gibson (Schneck); Hamilton 
(Wilson); Jefferson (Coulter); Knox (Ridgway); Kosciusko (Coul- 
ter); Lake (Barnes); Marion (Wilson); Monroe (Blatchley); Noble 
(Van Gorder); Posey (Schneck); Putnam (MacDougal); V go 
(Blatchley). 
Halésia diptera Ellis. SNowpropr Trer. (Halesia carolina Lin- 
nus). This tree has been admitted to our flora upon the authority 
of Robert Ridgway who reported it as occurring near Evansville. 
Mr. Ridgway says he quoted from some standard authority but 
can not recall where he saw it. Since the range of the species is 
much to the south of our area it is not included in this list. 
Fraxinus caroliniana Miller. Water Asu. This species was in- 
cluded in Coulter’s catalogue of Indiana plants upon the authority 
of Dr. Schneck. It is asserted that specimens were verified at the 
Shaw Botanic Gardens, but an examination of the material there 
showed that no specimens from Indiana were deposited there.
