[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.
[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.
[49]Morus alba LinnÆus. White Mulberry. A small crooked tree; leaves ovate, sometimes lobed, blades 6-13 cm. long, cordate at the base, acute at apex, at maturity glabrous above and glabrous beneath or with some hairs on the veins and in the axils of the veins; fruit subglobose or oblong, 1-2 cm. long, white to pinkish. This is an introduced tree and has been reported as an escape in many parts of the State, especially by the older botanists. Morus alba variety tatarica Loudon, the Russian mulberry, has been reported as an escape. The writer has seen single specimens as an escape in woods in Cass and Marshall Counties. It can be distinguished by practically all of the leaves being more or less lobed and the reddish fruit. This form was introduced into the United States in great numbers about fifty years ago by the Mennonites. It was especially recommended by nurserymen for fence posts and it has been planted to some extent in Indiana, but it cannot be recommended. It grows too slowly and is too crooked to compensate for any lasting qualities the wood may have. Morus nigra has been reported from Indiana by Phinney, Brown and McCaslin as a forest tree. Since this is an introduced tree, and is not supposed to be hardy in our area, their reports should be transferred to some other species.

He says: "Fifty trees were measured at three feet above the ground with an average diameter of 2 ft. and 9 inches. An equal number of Æsculus octandra were measured at the same height from the ground with an average diameter of 2 ft. and 9 inches."

[83] 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.
