The species name acaule is Latin, meaning, "stem less", which refers to the plant's leafless flowering stem.
Pink Lady's Slipper is highly dependent on a fungus in the soil from the Rhizoctonia genus. It requires this fungus to germinate and to symbiotically exchange nutrients, so it is ill-advised to ever attempt to transplant a specimen.
According to a USDA Forest Service webpage (2014),
"The root of lady's slipper was used as a remedy for nervousness, tooth pain, and muscle spasms. In the 1800s and 1900s it, and other orchids, were widely used as a substitute for the European plant valerian for sedative properties."
