TREES OMITTED FROM THE PRESENT List WuicH Have BEEN RE- 
PORTED AS NATIVE TO THE STATE. 
It should be borne in mind that the forests of Indiana have under- 
gone many changes since the first list of Indiana plants was pub- 
lished in 1819. Many birds and mammals have vanished from our 
area, and it is not unreasonable to believe that many of the plant 
forms also have disappeared after the advent of the ax and plow. 
In the preparation of the present list of trees of the State, a criti- 
cal examination has been made of the records of all the trees that 
have been reported as being native to th- State. This seemed 
advisable in order that the present work might not be burdened 
with the discussion of unnecessary species and to correct errors if 
any existed. 
Pinus rigida Miller. Prrcu Ping. This species was given by 
Baird and Taylor as occurring in Clark County in a flora of the 
county published in the manual of the schools of Clark County, 
Indiana, 1878-1879. The range of Pinus rigida is east of our areca, 
and since the authors did not include in their list Pinus virginiana 
(Scrub Pine), which is frequent on the knobs, it is believed the 
reference to Pinus rigida should be referred to Pinus virginiana. 
It is to be noted that Prof. Stanley Coulter, who knew the authors 
of this flora and who is well acquainted with the trees of that 
vicinity, ignored the reference in his catalogue of the plants of 
Indiana. 
Chamecyparis thyoides (Linnzus) Britton, Sterns and Poggen- 
berg. WuitTs Crepar. This tree was given a place in our flora 
upon the authority of Dr. C. R. Dryer of Ft. Wayne, who reported 
it from Allen County. All efforts to verify this record have failed. 
Dr. Drake in his picture of Cincinnati, published 1815, page 83, 
says,—‘‘The White Cedar and Cypress are found on the banks of 
the Wabash.” Since the range of this species is given by Sargent 
as along the Atlantic coast from Maine to Florida, it is improbable 
that it occurs within our area. 
Populus balsamifera Linnzus. Batsam Popiar. This species 
is reported by Bradner from Steuben County, where it may occur. 
The writer has a leaf specimen collected near Gage Lake in Steuben 
County, which if taken from a mature tree is unquestionably from 
balsamifera; if from a young tree, it may be grandidentata. In a 
reply to a letter addressed to Mr. Bradner asking if he had speci- 
mens from the tree on which his record was made, or if he knew 
where the tree was to be found, or if the record he made was from 
a cultivated or an escaped tree, he says he had no specimens and
