There are two species of gymnosperms and 18 monocots that are near the southern edge of their geographic range in Cedarburg Bog (Reinartz and Reinartz 1981). Six of these may actually reach their range boundary in the bog. Nine species of the Cyperaceae and seven Orchidaceae comprise the bulk of the monocot species that are near their southern limits. The purpose of this paper is to provide an annotated listing of dicot species which have geographically marginal populations in Cedarburg Bog.

In a previous article, Reinartz and Reinartz (1981) described the monocot and gymnosperm plants that reach their range limits at the Cedarburg Bog. The bog forest consists primarily of·white cedar (Thuja canadensis) and tamarack (Larix laricina) and includes a string bog plant community, all typical of wetlands further north. The summer fauna also possesses an ecologically northern relict flavor. This is especially true of the most conspicuous vertebrates, the birds. Many bird species found in the bog are more closely associated with the transitional and boreal forests of Canada and northern Wisconsin than with the deciduous forests and fields that …

Marginal populations are those located at the extreme or periphery of a species' range. In the context of this paper, marginal populations refer to a geographical periphery rather than to possible ecological margins. A wide ranging species may be composed of several different varieties or ecotypes. Marginal populations of plants are of special interest to plant taxonomists, ecologists, ecological geneticists and biogeographers because they may exhibit different characteristics than more centrally located populations. This is likely because plants at the boundaries of their species' range may experience extreme ecological conditions beyond which they cannot survive.
