Trees Omitted from the Present List Which 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 Hst 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 the 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. Pitch Pine. This species was given by 

 Baird and Taylor as occurring in Clark County in a flora of the 

 county pubhshed in the manual of the schools of Clark County, 

 Indiana, 1878-1879. The range of Pinus rigida is east of our area, 

 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. 



Chamsecyparis {thyoides (Linnaeus) Britton, Sterns] and Poggen- 

 berg. White Cedar. 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 Linnaeus. [Balsam Poplar. 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
