Yellow Lady's-slipper Cypripedium parviflorum (Cypripedium calceolus) The classification of our native yellow lady's-slippers has not been settled. Formerly, they were considered to be the same species as Eurasian yellow lady's-slippers -- Cypripedium calceolus. The modern trend is to separate the American plants from the Eurasian, but the number of American species is under debate. Some botanists recognize two species in northeastern U.S. -- Cypripedium parviflorum and Cypripedium pubescens, but these species are defined differently by different authorities. On this site, we are following the Flora of North America, which classifies all yellow lady's-slippers of northeastern U.S. as Cypripedium parviflorum. Yellow lady's-slipper is rare in Connecticut; it is classified as a species of special concern in the state.
Family: Orchid (Orchidaceae)
