University of Wisconsin Field Station Annual Report 2009

A New Inventory Species, Carex buxbaumii, in Cedarburg Bog by Linda Curtis.

Carex buxbaumii. dark-scaled sedge, was discovered  June 22, 2009 growing along the plank walk approaching the river.  C. buxbaumii usually grows in calcareous marshes  and prairie swales and was also collected in the UW-Milwaukee Field Stations, Chiwaukee Prairie, a sand prairie, and Benedict Prairie, a clay prairie, both in Kenosha, County. The Cedarburg Bog specimen exhibited fasciation, an altered morphology with flattened thick culms and multiple spikes. The specimens were verified as C. buxbaumii by Dr. T. Cochrane of the UW-Madison Herbarium, also  Dr. Andrew Hipp , curator of the Morton Arboretum Herbarium, Lisle, Illinois, and Dr. Anthony Reznicek, curator of UM- Ann Arbor Herbarium. This brings the site inventory number of Carex in Cedarburg Bog to 50 species. Other Carex specimens collected from near the river area included C. comosa, C. interior, C. pseudocyperus and C. stricta. The plants were photographed, scanned, and parts micro-imaged for the author’s next book about Carex of bogs, fens, coniferous swamps, and wet prairies of the upper Midwest.
