Edward, Sarnia, Lambton Co, Ontario) could not be verified {\textendash} colllections were as easily assignable to either Q. velutina or Q. ellipsoidalis (DAO collection) or obviously Q. velutina, but apparently not from the original tree (Dodge and Tripp, 1959, MICH). Ball noted a 1957 collection by Tamalu from just W of Galt, first det by Tamsalu as Q. coccinea, then redet as Q. velutina (notes that Fox and Soper 1954 concluded "Q. coccinea" of Southern Ontario should all be refered to other species, primarily Q. palustris and Q. velutina). 1978 fieldwork uncovered similar trees throughout N. Dumfries Twp in Regional Municipality of Waterloo, and in Brant Co, northern part of S. Dumfries Twp. Hill{\textquoteright}s oak distinctness and identity Ball summarizes Jensen 1977 publications demonstrating that Q. rubra, Q. palustris, Q. shumardii, Q. nuttallii, Q. coccinea, Q. ellipsoidalis, and Q. velutina "are all reasonably distinct species." The first four spp were distinct from the Waterloo, Brant specimens, but the latter three "cannot be so readily distinguished." "Quercus ellipsoidalis has no unique characters, but it can be readily identified by a combination of characters, particularly the slender petiole; small, glabrous or sparsely pubescent terminal buds; and the small, turbinate, unfringed acorn cup." NOTE: Ontario Q. ellipsoidalis is reported as being sparsely pubescent all over on the inner face of hte acorn cap; Jensen says it is altogether glabrous. Ecology Almost all stations are in old fencerows or hedgerows, sometimes in forest edges, never in forest interior. Some close to ponds or small lakes. Soil almost always has high sand content {\textendash} trees often growing with prairie plants such as Andropogon gerardii, Schizachyrium scoparium, Sorghastrum nutans, Lespedeza capitata. at the time of settlement, Dumfries Twp was mostly dry grassland with open-grown oaks and frequent fire.},

	abstract = {Hills oak (Q. ellipsoidalis) is reported from several localities in southern Ontario near Galt and Brantford. This represents an eastward extension of the range of the species of > 200 km. In most localities in this area the trees occur in fence rows and hedgerows, and with the increasing urbanization and road widening that is occurring, many are in jeopardy. The distinction between Q. ellipsoidalis, Q. coccinea (scarlet oak) and Q. velutina (black oak) was made from leaf, bud and acorn characteristics.},
