Two forest stands in the forest-prairie region of central Missouri were analyzed. The stands, considered examples of undisturbed forest, were situated on north and northwest-facing slopes, underlain by deep, porous soils of loessial origin. The random pairs method cited previously was employed in obtaining field data. Percentage frequency, density, and basal area were calculated for each species. The summation of these values was used to express species importance in the stand. Calculations showed that the leading dominants common to both stands were collectively Acer saccharum and A. nigrum, and Tilia americana. Ulmus rubra and Quercus rubra were other prominent species, in one stand or the other. The most prominent species of the understory in both stands was Ostrya virginiana. Tentative climax adaptation values were applied to data in determining a continuum index for each stand. The indices ranged from 2531 to 2542 out of a possible total of 3000. Additional stands are needed for further investigation. Comparison of lesser vegetation with that of Wisconsin and Minnesota stands referred to previously indicated that certain species common to the Missouri forests drop out in northern portions of the prairie peninsula. These included Asimina triloba, Cornus florida, Sassafras albidum, and Fraxinus quadrangulata. Studies of sugar maple-basswood stands in central Missouri on the southern edge of the prairie peninsula indicated similarity to those in more northern sections of the forest-prairie region.
