1. Study of the river-facing bluffs of the Missouri River was undertaken to gain a more accurate concept of the differences that appear to exist between the opposing bluffs. 2. In order to provide a basis for discussion, a brief description of the order of succession on these river bluffs and their plant associations is given. 3. The order of succession was found to be the same on opposite sides of the river. 4. The rate of succession is faster on east-facing bluffs. 5. East-facing bluffs excel both in number of individuals and in variety of species. 6. Corresponding associations are found higher on east-facing than on west-facing bluffs. 7. A greater area is occupied by the linden-ironwood climax on east-facing bluffs than on west-facing bluffs. 8. These differences, as well as the treelessness of west-facing bluffs, appear to result from the high rate of evaporation caused by prevailing winds during the growing season. 9. It is hoped to study in detail the environmental factors in the various plant formations and associations on the Missouri River bluffs.
