Abstract
The hemlock, Tsuga canadensis, exhibits a very disjunct distribution in Ohio, Indiana, Illinois, Michigan, Wisconsin and other parts of the western and southern limits of its range. In Indiana and parts of its range farther northwest it is usually limited to steep slopes, canyon walls and deep ravines, though in some stations in Indiana, such as at Turkey Run, in Parke county, and Pine Hills, in Montgomery county, it occurs on plateau tops and stream terraces.
