Abstract

The following article is the result of more than twelve months spent in botanical field work in the Black Hills during the summers of 1924 to 1930 inclusive, and of a review of the literature dealing with the exploration, geology, paleontology and botany of the region. In order to form a suitable background for a proper understanding of the environment of the modern flora and tot approach the subject from a historical standpoint sections on geography, geology, soils, climate and fossil plants have been included. As each section is more or less a unit, certain ones, such as those on geography, geology and climate may be omitted by the reader already familiar with such features. A fairly complete bibliography is appended, which should be of value to any reader desiring furhter details.
