Abstract
"The purpose of this study is to clarify and enlarge upon a previous research which defined the fossil flora of the Lower Coal Measures of Missouri. The former study was based almost entirely on materials that had been collected by individuals in Henry County, Missouri, who had forwarded the floral elements to Washington, D. C. for Identification. Since such collections usually are made up of better preserved materials rather than of all the taxa that may be present, it was felt that the previous collections may have contained a bias and hence the report did not give a complete picture of the flora. Recent information on the Rowe coal reveals an extensive area in which the stratum is exposed. It is questionable whether the previous study, based on a very limited area, gave a true representation of the fossil flora found stratigraphically between the Rowe coal and the Dry-wood coal. It is also questionable whether the strata were accurately defined if the specimens were mail order. Therefore, the major goals of this study were to collect plant macrofossils over a larger area to obtain a larger sample and to carefully define the strata from which these fossils were taken. Secondarily, the flora was also to be more carefully identified in light of the numerous studies made on the Pennsylvanian floras since the original work by White (1899). The flora will be compared with floras from other areas in order to determine similarities and to more clearly define the stratigraphic problems involved."--Introduction.
