Cypripedium montanum has previously been known from the northwestern states of the U.S. and from southern Alberta and British Columbia. A recent discovery of white-flowered lady's slipper orchids has extended the range of plants into the Black Hills of South Dakota. To verify the identification of the plants, living specimens of related C. parviflorum in the Black Hills were measured, as were specimens of C. montanum from the Big Horn Mountains. Cluster analysis and principal component analysis grouped the white-lipped plants from the Black Hills with C. montanum from the Big Horn Mountains. This is the first report of C. montanum in South Dakota and the easternmost report of the species in North America. [ABSTRACT FROM AUTHOR] |
