[8] Baird & Taylor's reference to this species is regarded as a cultivated tree or as an error: Manual Public Schools of Clark County, Ind. 1878-9, page 62. [9] Hamilton County by Wilson, no doubt from a cultivated tree. [10] Contributed by C. R. Ball, Bureau Plant Industry, Washington, D.C., except the genus Populus. [11] Coulter's record for Gibson County by Schneck is regarded as an error because Schneck himself does not report it, and there was no specimen in the Schneck herbarium. [12] Deam's record in Rept. Ind. St. Board Forestry 1911:124:1912 was a manuscript error. [13] Ind. Geol. Rept. 17:263:1892. [14] Sargent in Bot. Gaz. Vol. 64: 58:1918. [15] Heimlich in Proc. Ind. Acad. Sci. 1917:437:439:1918 credits most of my records jointly with Prof. G. N. Hoffer. This is an error. On my invitation Prof. Hoffer accompanied me nine days in the field doing mycological work. While he gave me valuable assistance in collecting during these days, his assistance and responsibility stopped there and he never asked or expected to be considered joint author. Again on our trip we collected only in Daviess, Gibson, Fountain, Knox, Lawrence, Martin, Pike and Sullivan Counties. [16] Sargent 1.c. [17] André Michaux's Travels 1793-1796.
