Ram's Head Lady's Slipper, Cypripedium arietinum, is a rare orchid found in dry to moist mostly coniferous forests in the Northeast from Nova Scotia to New York, west to Minnesota, north Manitoba. It was named in the 1813 edition of Hortus Kewensis. Overall this species continues to decline and is classified as Near Threatened by the IUCN Red List. It is reported in James William Herrick's 1977 iconic ethnobotanical dissertation Iroquois Medical Botany that the whole plant was used in decoction and as a poultice for intestinal problems with pain. The Iroquois name for this, our smallest, Cypripedium, translates to hummingbird house.
