The original forest, however, was doubtless made up chiefly of oaks, hickories, maple, beech, basswood and elm, with the trees mentioned above as secondary species. Since the soil was of fine agricultural quality, the forest has almost entirely given way to farms. One is urged to visit Rondeau Park if he wishes to see a magnificent remnant of the forest type that originally covered the area.

The southern relationship of the flora is also strikingly shown by the herbaceous forms. Probably fifty species or more, many of them ranging as far south as Florida, are found in Canada only in the region described above. Among these may be mentioned: Rue anemone (Ranunculus thalictroides)

corydalis (Corydalis flavula) ; mouse-ear cress (Sisymbrium thalianum) ; swamp saxifrage (Saxifraga pennsylvanica) ; Indian physic (Gillenia trifoliata) ; wild indigo (Baptisia tinctoria) ; wild lupine (Lupinus perennis) ; hoary pea (Tephrosia virginiana) ; tick trefoil (Desmodium pauciflorum)

bush clover (Lespedeza virginica) ; Carolina vetch (Vicia caroliniana) ; flax (Linum virginianum) ; milkwort (Polygala sangitiuea) ; flowering spurge (Euphorbia corollata) ; swamp rose mallow (Hibiscus moscheutos) ; great pinweed (Lechea villosa)

loose-strife (Lythrum alatum) ; harbinger of spring
