Abstract

The rather uniform till plain topography of Indiana would seem, naturally, to imply a homogeneity and uniformity in the plant cover; such, however, is not the case. Friesner has indicated that the state is in a critical location in reference to the distribution and geographical limitations of numerous and varied plant species.

These vegetational differences are especially marked when forest types within the deciduous forests are involved. Potzger has found that microclimatic features are of sufficient importance to vary expression in oak-hickory or beech-maple type by the mere difference of south- or north-facing ridge exposures.
